No matter how ambitious your goals are when you first think of creating a custom software solution, strict budget and deadline constraints can easily dash them. So, what should you do in this case?

Specifically, before your tech team starts implementing a healthtech solution, you can choose two different paths for them: native and cross-platform mobile app development. In the vast majority of cases, in this area, the second option can cover all the needs and requirements for the project without harming its critical aspects, such as usability, performance, reliability, etc. At the same time, you will be able to launch your product on the market faster and save your financial resources. 

However, such a development process is somewhat different from the one that precedes the launch of several native applications. Below, we'll cover how these differences can impact critical aspects of your project and share insights that help you fix them.

Best Practices for Cross-Platform Development in Healthcare

Since cross-platform app development involves adapting a healthcare solution to multiple platforms at once, it is important for the team to adhere to the following best practices to ensure the proper quality of the resulting solution.

Compliance and Security

The first thing you should probably start the development process for the healthcare industry is to ensure compliance with generally accepted standards and policies. The most common among them are HIPAA (Health Insurance Portability and Accountability Act) and GDPR (EU regulation aimed at giving citizens control over their personal data). Along with that, software engineers must use standard security mechanisms such as encryption, integration of secure connection certificates, etc. Ultimately, it is better to check the requirements for medical software development according to the legislation in force in a particular region – this way, you will not face any fines and bans.

User Experience (UX) Design

Now, let's talk about user experience in health apps – it should be smooth regardless of the platform they are running on. Since many healthcare mobile applications are positioned as an alternative to offline services from legally operating medical institutions, they must comply with accessibility rules that are described in detail in WCAG 2.0. These guidelines allow developers to implement seamless interaction with medtech solutions for people with all kinds of disabilities. Depending on the type of medical tasks assigned, you will need to ensure that your healthcare app UI/UX design meets WCAG 2.0 requirements to the appropriate level.

Performance Optimization

Nowadays, high performance is considered one of the key aspects ensuring the app’s survival in the market; however, in the healthcare sector, this parameter is much more critical since someone's life may depend on it. Indeed, if your digital solution involves an urgent call to a doctor, lags in its functioning may end tragically for some of the users. At the same time, it is believed that native applications work faster than those created in the process of cross-platform or hybrid app development. This is not true – such modern development tools as React Native, Flutter, Ionic, and many others allow teams to build software with complex business logic without reducing its speed. Of course, these frameworks will not handle resource-intensive gaming applications, but, most likely, this is not the original task. Whatever approach and technology stack you choose, your team involved in software development for healthcare will need to spend some time testing the application before launching and ensuring that it works equally effectively on all platforms.

Testing and Quality Assurance

Yes, we have already outlined the importance of this process above, but we will repeat it once again: no application can be launched for public access before it has passed a series of tests, both with the participation of the team itself and involving focus groups assembled from representatives of the target audience of your software. The most common types of testing are modular, integration, functional, acceptance, system, smoke, and so on. Each of these types takes place at a certain stage of development (and has to be performed on each platform separately), but the amount of code covered by test cases and the number of iterations will directly depend on the established deadlines. 

Integration

Finally, it is worth saying a few words about integrating your app with existing third-party products and services that your organization already uses. This is usually necessary to expand the functionality of the former and, in particular, to ensure seamless data transfer between applications. However, while the vast majority of modern custom healthcare solutions integrate via API, it is quite predictable that your team will face some issues if you use legacy software. For this, an additional middleware will have to be developed – it will take responsibility for converting data to the required format and back.

Conclusion

In general, as you may know, cross-platform development is cheaper than native development, because most of the code is reused between platforms, and you do not need to hire two separate teams to create native software for each of them (in particular iOS and Android). Moreover, with the right approach, frameworks such as Ionic allow you to build both mobile cross-platform and web applications, reusing most of the code, which, in turn, speeds up and reduces the cost of development for mobile and web platforms, respectively.

So, now, knowing the specifics of developing solutions using cross-platform app development tools, you will be better informed about how to ensure their proper quality and control each stage of their creation. However, if you would like to outsource this complex task without unnecessary doubts so as not to spend too much time on supervising, feel free to contact us.

In the design and operation of digital products, it is essential to detect errors and ensure that these products fully comply with specifications (both generally accepted and defined by their owners). For example, in the field of healthcare, using such solutions directly impacts the health and life of patients and the level of efficiency of medical services. So, let’s delve into this topic. 

Objective of Quality Assurance in Healthcare App Development

So, let’s find out why QA is important. In general, it is one of the integral parts of software development, especially in the medical field. After all, in the field of medical services, the fate of the patient's life and health is decided every day. Digital solution that looks and operates as intended (of course, thanks to the quality assurance benefits) provides the ability to prevent all potential errors as efficiently as possible and ensures that applications meet modern medical standards. 

Regarding the importance of quality assurance in healthcare applications, the following points can be distinguished:

• Safety of patients: At the heart of QA in healthcare software development is patient safety. The timely testing of healthcare applications that could impact a patient's health is a critical aspect. This includes verifying medicine dosage, ensuring the accuracy of diagnostic algorithms, and the functionality of the patient monitoring system. Any malfunction, even for a brief period, can lead to serious errors, underscoring the importance of reliability assurance.
• Data privacy: The guarantee of absolute protection of patients' personal data from unauthorized access. Due to their specificity, medical applications regularly process a huge amount of information, so the introduction of modern encryption methods is critical.
• Compliance with regulatory requirements: A number of modern healthtech standards like HIPAA and GDPR are created for a reason. Therefore, absolutely all software should be developed to meet these requirements. Civilized countries actively implement official app development rules. If these laws are ignored, it is undoubtedly a direct path to legal accountability, with all the attendant consequences. The implementation of reliable digital solutions reduces the chances of getting a fine or a lawsuit until the loss of a license.
• Optimization of regular processes: The higher the efficiency of the application, the better the performance and accuracy of work within the medical professional team. In this way, medical staff can access the necessary information, thus minimizing the time spent on data processing. This guarantees both speed and high accuracy of decision-making regarding the further treatment of patients.

Risks Associated with Poor Software Quality in Healthcare

No one will argue that some medical institutions ignore the risks of using legacy software that doesn’t meet the modern healthtech regulations. However, this is a very serious and critical topic that can significantly impact patients' safety and lives and the effectiveness of daily processes.

Numerous errors, incorrect diagnoses, and, as a result, incorrectly prescribed treatment all directly threaten the patient's life and health. Also, do not exclude the occurrence of legal and reputational problems (fines or a prominent indicator of loss of confidence on the part of the public, both patients and employees of a particular medical institution). Unreliable digital solutions automatically complicates the interaction between employees. It leads to a decrease in the productivity of daily medical practice because it complicates the possibility of uninterrupted access to all necessary data and the exchange of information between departments and specialists.

Types of Testing in Healthcare Applications Development

There are different types of healthcare application testing, but the most common and popular among them are the following types:

• Performance testing: It includes analyzing the application's speed of action and navigation, taking into account different levels of load.‍
• Regression testing: It defines how much each of the module functions meets the requirements.‍
• Security testing: It implies checking the protection of each patient's data from illegal access by unauthorized users.‍
• Usability testing: This example of quality assurance in healthcare is designed to evaluate how user-friendly the application is, ensuring it is convenient for both healthcare industry employees and patients of all ages.

Healthcare app testing features are primarily critical, including the need for strict compliance with regulatory requirements and safety regulations.

The Future of Quality Assurance in Healthcare

Now, knowing the answer to the question: “What is quality assurance in healthcare?”, let’s talk about its future. Specifically, today, we can define three the most sustainable trends:

• Implementation of AI and ML-based solutions aimed at automating the testing process, independently identifying bugs, and preventing them in advance;
• Combination of DevOps and Agile, which ensures closer interaction between development and testing teams, ultimately reducing the number of bugs and speeding up their fixing;
• Using cloud-based testing platforms that provide scalability of QA healthcare scenarios without compromising the budget.

However, in the coming years we can expect something more revolutionary than the actualization of the above-mentioned directions since the healthtech sector is actively invested in by both governments and private institutions.

Conclusion

Now, you know the answer to the question: “What is quality assurance?” and can understand the role of QA in software testing – generally speaking, it is crucial regarding ensuring patient safety and the performance of the healthcare delivery process. Minimizing risks during the medical quality assurance process and creating reliable medical applications are possible only through the use of modern technologies and compliance with all official standards provided by a qualified service provider.

Most likely, you would like to make your digital product highly competitive, get guarantees on its relevance, and avoid its costly rework even if its life cycle exceeds the unspoken five-year limit, right? Then, in today's changing tech environment, endowing it with long-distance growth prospects will be not just another strategy you may follow or not – it will be a necessity. 

What Is Future-Proofing?

No one would dispute that guaranteeing long-term stability adds confidence to the development process. Based on this, you may have a question: “What is the future-proofing?”. Now, we will explain the future-proofing meaning.

In short, it is the creation of several applications, websites, and services that retain their functionality even after a long time. For example, in the context of mobile application development, it predicts the occurrence of potential changes in the operating systems of gadgets so that these applications remain practical and relevant. By considering possible technological advancements, likely competitors, and requests from the target audience, the need for large-scale updating is minimized.

This process consists of analyzing a number of technological trends, considering potential risks, and integrating adaptive solutions to market trends. But do not close your eyes to some problems and challenges of future-proofing. There may not be a specific update date, and the implementation of flexible solutions may require both additional time and additional money. You should be sure that the tools and methods you use guarantee high quality and a high level of reliability of the product so that the process of its development is productive and relatively simple.

In addition, an equally important aspect of the above-mentioned approach is the study of potential changes that may occur in the needs and behaviors of the target audience of your product. This will make you ready to overcome obstacles. Let’s take a concrete example, if you integrate software with cloud services (using self-testing and scaling architecture).

The Benefits of Future-Proofing Software

It is worth considering the most striking advantages of this software to make sure it is appropriate:

• Flexibility in a dynamic technology environment: This helps to adapt existing products to new requirements.
• The real prospects for the future: The more long-term prospects are taken into account during the future-proof development of the digital solution, the longer it is guaranteed to be stable.
• Optimization of financial costs: If the potential upgrade of the review is done immediately at the development stage, it minimizes the possibility of costly disposal of the product itself.
• Superiority over competitors: Service providers that offer better protection of their decisions, respectively, are much more efficient and faster to respond to constant changes in the market and the needs of their target audience.

Future-Proofing Methods

You should also pay attention to the most popular ways to improve your digital products in the long term:

• Quality Assurance: Stable support of high-quality standards is a direct path to product reliability.
• Modularity: Modular architecture simplifies processes such as updating and modifying specific required components, minimizing any impact on the entire system.
• Documentation: Detailed documentation that is regularly updated to facilitate further support and streamlining.
• Implementation of modern standards: Strict adherence to the latest quality standards increases the adaptability of your products to innovative technologies several times.

7 Ways to Future-Proof Software

Let's dwell on the seven most essential methods for reliably protecting your software from upcoming challenges and guaranteeing its stable operation for many years.

Implementation of automated tests

Automated tests allow you to quickly detect and correct errors that occur when making changes to the code. This dramatically reduces the risk that new features or updates will break existing functionality. In addition, automated testing increases development efficiency, reducing the time for manual QA procedures.

Using containerization

Containers provide software flexibility and portability, making it easier to deploy across platforms. They isolate the application and all its dependencies, which avoids problems with environment compatibility. Containers also simplify application management in several environments at once.

Expanding of architecture

Planning the architecture for possible load increases makes it easy to scale the system. Using a microservice architecture, a design pattern that structures an application as a collection of small, loosely coupled services, for example, enables the scale of individual components independently, increasing the system's overall performance and reliability.

Integration with cloud services

Cloud solutions provide flexibility and the ability to adapt to new requirements quickly. They allow you to store and process data on remote servers, reducing infrastructure costs and achieving higher availability and service reliability.

Regular updates and patches

Constant software update allows you to maintain its relevance and reliability. Regularly fixing vulnerabilities and adding new features helps to avoid obsolescence and ensures it meets modern security standards.

Using open standards and APIs

Open standards are publicly available specifications that facilitate interoperability. APIs are sets of rules and protocols that allow different software applications to communicate with each other, be compatible with other systems, and simplify integration. These make it easy to connect new services and expand the existing functionality without significant changes in its architecture.

Investing in team training

Investing in team training and focusing on long-term planning is crucial to preparing to embrace new technologies and methodologies. This ongoing evolution of skills and knowledge not only enhances employees' current abilities but also prepares them to adapt to fluctuations in the tech market.

Conclusion

Future-proofing your software, through robust security measures such as encryption and regular vulnerability assessments provides you with long-term stability and high competitiveness. At the same time, you get a significant reduction in the cost of service and increased flexibility and speed of adaptation to a number of new requirements and conditions, which in the complex creates the conditions for the adaptability of the entire team. In this way, your software will always be efficient and reliable despite the changing technology environment.

It's crucial to note that the strategic approach to software protection and development is not just about the technology but also the people behind it. This approach stimulates the development team's performance, ensuring efficiency and effectiveness through process standardization and the introduction of the latest technologies. By empowering your team to implement new features and optimizations, this approach makes them feel valued and integral to the process, thereby increasing performance.

Hey, are you here to find a solution for a consolidated and easy-to-access “home” for your business information, which is usually transferred from different places, often unrelated to each other? Then, you probably need to think about creating a digital space where it will be integrated, cleaned, structured, and stored accordingly, for further use in your regular business operations. But what is this space? Let’s find it out right now.

What Is Data Warehousing?

In a nutshell, it is a repository where your business data comes from disparate sources, where it is brought to the proper quality, and where it is stored, providing individuals with the appropriate rights with easy and fast access to it. Typically, such repositories serve as one of the central components in automated analytical solutions, but, as practice shows, the range of their application can be much wider.

Key Components of a Data Warehouse

In general, its main components are considered to be the following:

• Sources, from which structured and unstructured information comes – these can be third-party databases, tables, systems, applications, etc.;
• Data Extraction, Transformation, and Loading (ETL) tools, which define scenarios for extracting, transforming, and loading the information;
• Data warehouse database, which is the main repository (usually in the form of a database management system, DBMS) with already prepared, i.e., cleaned and structured data, that can be used for analytics, reporting, and other business tasks without additional manipulation;
• Metadata repository, which includes the permissible data types and the rules according to which this data will be used;
• Query and reporting tools, which define algorithms for fast and unified access to data, as well as its analysis;
• Data mart, a subset of the data warehouse that is used for individual business tasks (this can imply, for example, marketing data warehouse design) which formation occurs either directly through the collection from disparate sources or pre-preparing within a consolidated space.

Core Principles of Data Warehouse Design

Now, let's talk about the main data warehouse design principles:

• A clear definition of business requirements and goals, as well as metrics that allow you to objectively assess the degree of their achievement;
• Understanding how information is integrated from multiple sources and what should be the unified format after its transformation;
• Choosing the right type of data modeling – these can be star schemas, snowflake schemas, fact tables, and so on;
• Choosing the right methods and data warehouse software to ensure the quality and consistency of information, in particular, the methods of cleansing, validation, and supplementing of data;
• Planning, scaling, and managing the performance through various methods of indexing, partitioning, compression, etc.;
• Choosing the right tools for metadata management to simplify and improve access to the information;
• Ensuring security and access based on policies and rules (usually, this is achieved through the implementation of advanced encryption algorithms, the introduction of access policies for different user groups, as well as providing reliable authentication and authorization methods);
• Implementing end-to-end monitoring for ensuring data quality and security, performance of processes occurring within the data warehouse, and so on.

Steps in Data Warehouse Design

In this section, we invite you to consider the key steps leading to a successful and agile data warehouse design.

Requirement Gathering

According to the principles to design a data warehouse we defined above, the key to effective data warehouse design is to gather business requirements and clear business goals that it should fulfill. It is also important to identify the requirements for security, scalability, and performance of the repository.

Data Modeling

This is not yet a practical stage, but it still requires the participation of specialists – in particular, it implies the identification of entities, their attributes, as well as possible relationships between them. After this, the most suitable type of DBMS implementation needs to be selected – for example, in the form of tables, columns, indexing, etc. After this, you have to make sure that the selected type performs all the tasks assigned to it according to the predetermined requirements.

ETL Process Design

We have already explained above what the ETL process means, and this stage actually involves choosing the right tools and scenarios for their use.

In particular, you will need to define methods for extracting information from disparate sources (these can be database queries, API calls, file transfers, etc.), methods for bringing data to a single format and ensuring its proper quality (since you will most likely have to deal with big data, there may be many inconsistencies), methods for aggregating data to create complex information structures, automation methods for bulk loading of data (this can be full or incremental loading, and so on) with the usage of temporary storage areas, methods for detecting and eliminating data errors, as well as methods for checking data for completeness and accuracy.

Database Schema Design

There are several well-known data warehouse design patterns, such as:

• Star, which has a fact table at its center and dimension tables associated with it around it;
• Snowflake, which is a more complex Star and also implies additional dimension tables that surround each base dimension table;
• Galaxy, which contains two fact tables and the dimension tables between them.

Data Integration

Now, you can start integrating the data using the previously defined ETL tools and technologies. At this step, you need to make sure that everything works as intended, and the data is transformed into the required unified format.

Data Storage Solutions

At this stage, you need to choose specific data storage solutions according to your requirements for the expected data volume, performance, scalability, and cost. Usually, the choice is made between relational databases, columnar databases, data lakes, and cloud data warehouse solutions.

Data Presentation Layer

Finally, to design data warehouse, you will need to understand what your data presentation layer will be – the layer at which end users will be able to seamlessly access the data and use it to solve specific business problems. This includes developing interfaces, dashboards, reports, and various data visualization tools.

Conclusion

Now that you have a clear guide to data warehouse design, you can begin implementing it with a full understanding of the principles and stages on which it is based. If you would like to delegate this comprehensive task to seasoned data warehouse development specialists, just contact us.

If you are working on a digital solution, one of its integral stages will be UX/UI design. While trivial projects usually have “beaten” paths for creating navigation and visuals, any deviation from the standard can lead to dissatisfaction among end users and increase the entry threshold for them. In this regard, no matter how sophisticated the logic of your project is, it is important to understand the usability principles maintained by human psychology to ensure its excellent user experience.

Theories of Perception in UX/UI Design

Generally speaking, there are several popular theories of perception in UX/UI design:

• Gestalt psychology aimed at gaining an understanding of how people associate individual objects with things that are meaningful to them. The main gestalt principles include figure-ground (according to which some objects, depending on their visual appeal, are perceived as key navigation elements, while others serve as background), similarity (according to which elements with identical visual characteristics are perceived as interconnected), proximity (according to which closely placed objects are also perceived as related to each other), and closure (which states that incomplete objects, if sufficiently detailed, can be perceived by users as complete).
• Affordance theory, claiming that to ensure intuitiveness, users should receive some cues from the interface from the very beginning on how to deal with a particular element – one way to do this is to use skeuomorphism;
• Hick's Law, which states that the time it takes a particular user to make a decision is logarithmic to the number of available options (which means that to maximize intuitiveness, the user's choice should always be limited);
• Fitts' Law, stating that the time it takes a user to reach a desired part of the interface depends on its size and distance (which means that to ensure a great user experience, you need to place interactive elements closer to the user's starting point);
• Signal Detection Theory, claiming that users can subconsciously distinguish between meaningful cues (calls to action) and background noise, meaning that they should be visually separated.

Cognitive Load: Its Effects on UI Design

Now let's move from theory to practice and consider individual insights extracted from the above theories of psychology in UX. 

In particular, the first insight is the minimization of cognitive load, that is, the efforts of the human brain that must be applied to perform a specific target action. Thus, the importance of reducing the amount of information or tasks provided to the user becomes clear – otherwise, there is a high probability that the user will begin to act erroneously. 

In practice, such brevity can be achieved by correctly grouping interrelated elements and removing elements whose functionality duplicates each other.

Emotional Response & UX Design

Another valuable insight from UX design and psychology is to establish an emotional connection with the end user through your interface. This is a global task that begins with user behavior analysis and identifying their desires, pain points, and intentions and ends with transforming the obtained information into design elements that resonate with them. 

Ultimately, you will have to walk in the shoes of the average consumer of your software solution to ensure the proper level of empathy with your emotional design. In terms of practical implementation of the emotional response, such user empathy can be achieved through the integration of “user experience stories” that can be presented by a service provider to users as they get acquainted with the digital solution, as well as the use of the right color palette, forms, audio, pop-ups, and text.

The Role of Memory in User Interaction

Since, according to cognitive psychology in design, the average person can concentrate on one object for up to 20-30 minutes, it is important to take this aspect into account if your software solution involves long-term interaction with it. 

Specifically, you can reduce the load on your users' memory by implementing elements and scenarios that work and occur in a way that is familiar to them. Otherwise, if something does not function as expected, it can lead to users’ confusion and erroneous actions. 

Understanding User Behavior Through Heuristics

Heuristics are specific UI design principles that can predict user psychology. Here are some of them:

• Visibility of system status, which implies the importance of informing end users about what is happening with your software solution at the moment through progress bars, loading animations, or status messages;
• Match between the system and the real world, which emphasizes the importance of correspondence between the system's behavior and the knowledge and experience that users received before they became familiar with your software solution;
• User control and freedom, which implies the need to provide end users with the ability to freely navigate your software solution and manage negative scenarios;
• Consistency and standards, which determine the significance of logical connections between elements, terminology, and layouts;
• Error prevention, which consists of preventing erroneous actions by end users by providing them with unambiguous and understandable instructions;
• Recognition over recall, which states that to ensure better intuitiveness, users should “recognize” familiar patterns from the real world in elements and scenarios of your interface.

Thus, you have to perform a heuristic evaluation to check whether your solution is good in terms of usability. Also, note that in reality, there are many more psychology UI design heuristics, but the above list will be sufficient for a basic understanding of what is meant by the term excellent user experience.

The Impact of Attention on User Experience

Many designers, in order to encourage the user to perform a particular action, abuse pop-up notifications and other features to attract attention, thereby increasing the cognitive load, the inadmissibility of which we have already discussed earlier. 

Instead, you can use such approaches as the correct building of a visual hierarchy, optimization of the color palette, breaking down complex processes into several simple ones, etc. And, of course, do not forget to appeal to the memory of users, which already contains some experience of interaction with other digital solutions and can automate some processes of dealing with them due to the familiarity of the mental models implemented.

User Motivation & Reward Systems in UX/UI Design

Finally, from the point of view of UX psychology, many UX/UI designs benefit from gamification, which motivates users to move toward the target action. In general, gamification is aimed at boosting user engagement and creating an exciting user experience that they don’t want to interrupt. Its main elements are rewards and recognition.

At the same time, it is crucial to note that some reward systems are too confusing for the average user and, thus, create unnecessary cognitive load instead of motivation. Moreover, gamification is not considered a universal approach that could be used in any project. Therefore, you have to always start with the appropriateness and the affordance of implementing this concept clearly and simply for the consumer.

Conclusion

We hope that with the help of this article, you were able to understand the importance of UX design psychology and how it is implemented in UI/UX principles like heuristics, emotional response, lowering cognitive load, user motivation, and others.

As the practice shows, no idea, even the most brilliant one, when embodied in a digital product or service, will become successful without quality assurance. It, in turn, always includes two non-intersecting procedures that occur before software is launched: the first of them is aimed at obtaining a clear understanding of whether development is moving in the right direction, and the second of them clarifies whether the solution being created meets end user needs. So, how are they called and performed? Let’s find it out right now.

What Is Verification Testing?

In a nutshell, it is a procedure aimed at checking whether the solution being created meets its predefined specifications and generally accepted design and development standards. Software verification testing is performed throughout the entire creation process and involves the use of various automation testing tools and verification methods, such as modular, integrational, and system testing.

What Is Validation Testing?

Unlike the previous type of testing, this one involves planning real-world scenarios that allow the development team to make sure that the solution being created meets its audience’s needs (for this, you can apply, for example, the alpha- and beta-testing validation methods). After that, the solution has to be compared with its specifications. If any discrepancies are found, they need to be eliminated before this solution is released to the public. Actually, that’s why validation testing is repeated until the team achieves full compliance.

Purpose of Verification and Validation

The main goals of verification and validation testing are to fully satisfy the needs of the software solution owner and the audience as well. As soon as these procedures are successfully completed, the project can be launched.

Difference Between Verification vs Validation Testing

So, what about the verification and validation difference? Generally speaking, while verification is aimed at checking the compliance of a product or service with its list of requirements agreed upon between the development team and the owner, validation allows teams to make sure that this service or product will be positively accepted by its end users. 

In this regard, the first procedure starts from the very beginning of the development process and lasts until the final testing stage and the second – only after the product/service is completed. This also imposes certain differences on the test data used: during verification in software testing, QA engineers use sample data (in this regard, automation methods are often applied), and during the software validation – real data (usually, manual methods do a great job here).

How Are Verification and Validation Testing Performed?

Now, let's look at the four most popular approaches used for validation and verification in software testing:

• Peer reviews, which involve providing a software solution to focus group representatives for a certain period of time in order to obtain feedback on their experience of interacting with it;
• Assessments, which are left by focus group representatives after checking the solution for functionality and identifying errors and inconsistencies in it;
• Walkthrough, which implies a preliminary explanation to focus group representatives of how exactly to interact with the software solution, after which the latter leave their feedback on how well everything was clear and whether they think some areas need to be optimized;
• Desktop-checking, which includes reviewing the software code by specialists (in particular, software engineers).

Tips for Successful Verification and Validation

To ensure these two procedures go smoothly, follow these guidelines:

1. Define the tasks and goals you are pursuing through these procedures and what the results should be upon their completion;
2. Choose the specific tools and approaches you are going to use – they should cover all possible scenarios of user interaction with your software solution, as well as generally accepted software development standards;
3. Create a testing plan, where you will specify deadlines, available resources, and evaluation criteria (along with the acceptable minimum compliance);
4. Proceed directly to testing in order to identify bugs and inconsistencies that will need to be fixed before the project is released;
5. Involve representatives of the potential target audience and stakeholders in the testing procedure to get the most objective assessment of the quality of your team's work;
6. Don't forget to document and monitor the testing results from one bug fixing to another to understand the dynamics of improvements.

Popular Test Automation Tools For Verification and Validation

Although automated testing is considered a standard approach for verification testing only, sometimes, it also brings benefits when implementing validation testing. In this regard, we have compiled a small selection of popular tools that you can use for quality control in software:

• Selenium, an open-source web solution that supports a lot of programming languages, such as Java, Python, C#, and so on, as well as integrates with different frameworks;
• Appium, an open-source service for automated testing of mobile apps on iOS, Android, and Windows (both native, cross-platform, and hybrid ones);
• Robot Framework, an automation framework aiming at implementing acceptance testing and acceptance test-driven development;
• Jenkins, an automation server used for continuous integration and continuous delivery that streamlines the build, test, and deployment stages;
• TestNG, a popular testing framework that is actively used for testing Java-based software solutions;
• Cucumber, an environment for running automated acceptance tests written in Java, Ruby, etc.;
• JMeter, a perfect solution for performance testing of web apps.

Conclusion

We hope that we have helped you understand the difference between validation and verification testing, and now, you can also assess their importance in creating high-quality and competitive software solutions. You can also check out our blog to learn more about software development and design.

• Internet search: Look for companies with high ratings and many positive reviews directly through search engines (Google and so on). It is worth starting with the main search queries and gradually detailing them using filters or keywords. It is also recommended to browse companies' websites, articles, and blogs directly to be more guided in their expertise.‍
• Recommendations: One proven and reliable way to find real pros is to seek advice or recommendations from your colleagues, employees, or business partners. If your acquaintances already dared to outsource dedicated software development teams, you can directly ask people from your professional network who they can recommend and for what reasons.‍
• Implemented cases and portfolios: Carefully review the portfolios and cases of your potential partner. This will help you analyze the outcome of their previous projects and determine if their style and approach meet your individual requirements. It is also necessary to pay attention to those projects that are similar in structure and concept to yours.‍
• Social networks and professional communities: Social networks and professional communities (like LinkedIn) are great options for finding reputable, highly specialized outsourcing service providers and analyzing customer reviews. They are also an excellent way to get more information about your contractor and its professional connections.‍
• Freelance platforms: Upwork, Toptal, and Freelancer are useful platforms for finding and communicating with experienced specialized specialists. These platforms also provide access to a vast database of freelancer profiles, ratings, and portfolios, which will help you get a complete picture of their professional competence.‍
• Events and conferences on professional topics: By attending various specialized events, you can expand your network of social contacts. In addition, you can personally communicate with potential partners, ask them questions that interest you, and make more or less objective impressions of them.

What Should You Look for When Searching for an Outsourced Development Team?

Clear positioning

Each company excels in a specific area, focusing on a single or a few related directions, such as mobile and web development. This specialization ensures their expertise and quality in these particular fields. It's important to note that the best outsourcers refrain from attempting to offer design, coding, and a myriad of other services simultaneously.

The presence of the grads and their description

If an outsourcer sells the services of Junior, Middle, and Senior specialists, there should be clear descriptions of what they can do and at what level.

Consent to interview

Even if you plan to interview only some experts, asking the service provider representative if they are open to interviews is beneficial. This step lets you feel more involved in the selection process and ensures that the outsourcing company is transparent.

Cases

The cases may be so problematic that the outsourcer projects for other companies are under NDA, and details cannot be disclosed. Therefore, cases can be impersonal without specifying specific customers.

How Do You Evaluate an Outsourced Development Team?

It is worth paying attention to several main aspects to make an informed, balanced, and final decision regarding outsourcing software development to a dedicated team. Undoubtedly, the portfolio and successful cases should be reviewed first to evaluate their previous projects.

After that, assess the technical skills and ability to work with the tools and technologies necessary for your project. For practical analysis, conduct technical interviews or ask for a test assignment to verify their qualifications.

Pay attention to the level of communication. The remote development team should respond quickly to your requests, clearly formulate their thoughts, and be ready for regular reports.

Compare the cost of services, considering the value for money your future partners ask. No one will argue that when you hire software development team, the cheapest option is not always the best, so it is worth assessing the cost of services in the context of the overall quality of work and the results you will receive.

Clarify the guarantees and level of support after the project is completed when you try to find outsourcing companies. For example, reliable contractors usually offer a specific warranty period and post-project support to ensure the smooth operation of the product.

Finally, assess whether the outsourcer's culture and values match yours. This may not be the most pragmatic metric, but it is equally important during hiring remote outsource developer. Specifically, your contractor must share your values and be prepared to work according to your standards and requirements. This will ensure harmonious cooperation when you hire outsourcing team.

There are about 8.93 million mobile apps worldwide, with new ones popping up daily, but not each of them has a good mobile interface design. At the same time, those who have it, win the hearts of customers and earn millions of dollars. So, how can you achieve this goal? Let’s find it out right now.

What Is Mobile App Design?

Mobile app design is the visual identity of an app tailored to the user's behavior. It has two components: UI and UX. UI (user interface) is how the application looks, and what colors, fonts, icons, buttons, or other elements it contains. UX is how an app works, responds to user actions, and helps fulfill people’s needs.

Interface design for a mobile application calls for consideration of the specifics of mobile platforms, such as screen size, data input methods, battery level, and internet connection speed. You should bear in mind that design can have a big impact on the success and popularity of the product, its usability, and its attraction to users.

Key Principles of Mobile App Design

Creating the interface of mobile applications is a truly complex and multi-layered process. It can vary dramatically depending on what project the app is created for, who the target audience is, and what functionality its owner is looking for. However, there are a few fundamentals to keep in mind when designing.

Here are top basic mobile design principles:

1. Prioritize the user’s needs 
2. Focus on visual design
3. Make the app interface convenient
4. Make the content easy to read
5. Add some interaction
6. Optimize the interface for different mobile devices

User Interface (UI) Design Principles

Let’s define the most important user interface design principles.

Simplicity

An eye-catching and straightforward user interface is ideal. There shouldn't be too many interface elements that can confuse a user. Nobody wants to explore a new interface once an application is downloaded – instead, people just want to get what they need or have fun.  All they seek is simple products that “just work”, that’s why, you have to prioritize the main parts for design and remove the unnecessary ones.

There is a simple rule of thumb: one main action per screen. Each screen you design in your application should support a single, genuinely important action for the user. This makes it easier to learn and use. One hundred clear screens are better than a single cluttered one.

Consistency 

The interface has to be intuitive and easy to navigate. You can add a great feature or content, but if people can't find it, it doesn't matter. Mobile navigation should be consistent. To ensure navigation doesn’t require any explanation, you should use the right visual metaphors, and check that each navigation item leads to the appropriate place.

Feedback and Response Time

Feedback informs users whether they are doing the proper action or not. It can be audible (the ding of a new message notification), tactile (the vibrating signal for a new email or call while your phone is set to "silent"), or just visual. Feedback should be provided after each operation to show if it was successful. 

Feedback can be useful in responding to problems in four areas:

1. Locating: Where are you?
2. Current Situation: What's happening? Is it still going on?
3. Prospects: What comes next?
4. Effects: What did you get?

Quick, insightful, and observable feedback is essential to let people know their actions were noticed. The link between the activity and its effect should be clear so that users understand what happened, and what to expect next. Feedback is supposed to optimize and complement the user's experience rather than complicate it.

User Experience (UX) Design Principles

Now, we propose to list the key UX design principles.

Usability

Usability measures how easy and convenient it is for the user to interact with the interface of an application. It depends on the ease of navigation, structure, content quality, text layout, mobile app design, and a bunch of technical features. This aspect affects users' time on an app, conversion rates, and customer loyalty. 

Here are five components of usability:

1. Learnability: how easy is it for people to perform basic tasks the first time?
2. Productivity: how quickly can people complete tasks?
3. Memorability: when people come back to an application after a time out, how easily can they recover their skills?
4. Error recovery: how many errors do users make, how serious are they, and how easily can people fix them?
5. Enjoyment: How engaging is it to use the app? Does it help people accomplish their tasks? 

User-Centric Design

User-centered design is an approach that consistently identifies user needs and translates them into a product. The core value is to focus on what people are used to, on what is “easy” for them and meets their basic needs.

Figure out what users want from your mobile application. On a food delivery app, people want to see available propositions, and discounts, place an order, track a delivery, and that’s it. They don’t want to read the history of a local family restaurant and its owners - this information may be kept in subsections. 

Accessibility 

If you want people to use your app, make it easy to reach. First, make sure it’s available on all mobile platforms and devices. Secondly, remember about inclusivity while designing for mobile devices. Partially blind or colorblind people may also use your product. So, you should help them effortlessly use it by adding voice interaction, and alternative text for images and employing color-blind oriented templates. Additionally, let customers change the text size in the app to suit their visual requirements.

Best Practices in Mobile App Design

Creating an interface that is both attractive and user-friendly is a challenge and an art. To achieve a delicate balance between aesthetics and functionality, designers need to utilize best practices. 

User Interface and Navigation 

Navigation in a mobile application must be intuitive. Each button or link has to state its purpose clearly. All icons must be recognizable and standardized. 

Mobile UX design's best practice for icons is to tag them with text. Tagged icons ensure that the purpose is conveyed quickly and easily.  You can see this in the most popular apps like YouTube, Spotify, and TikTok. 

Content Organization and Data Entry

When directing user attention across the application interface, use visual hierarchy. Distinguish important elements from less significant ones by varying size and spacing. Features that stand out attract attention, and clustering related items makes them easier to understand. For better readability and differentiation between titles, subheadings, and body content, designers should use the proper font sizes and styles. 

As for good examples of great content organization, we’d like to pay attention to Airbnb, an illustration of minimalism and simplicity. People love it for its aesthetic graphic design, balanced font sizes and colors, and the absence of flashy elements or bright banners. Airbnb has also made booking real estate clear: users understand what they are paying for.

Input fields and forms are the basic parts of mobile apps and are also crucial in mobile design principles. Improving the total user experience requires making these elements efficient and usable. Make a user type as little as possible by utilizing default values and input masks. Give consumers immediate feedback on validation so they can fix mistakes quickly. To help users fill out forms correctly, provide them with informative error warnings and visual clues.

Usability and Accessibility 

If you choose the right color palette, you can greatly improve the user experience. Remember about color blindness and test how your app looks to users with different types of color perception. Use contrasting colors for text and background to make content easy to read for anyone and anywhere. Add some extra explanations if needed. 

For example, the choice of clothing color in an online store should have a text explanation to be understood by people with a violation of color perception. Also, consider how the interface will look on small screens.

Performance and Responsiveness 

Take into account a diverse range of screen sizes and resolutions. Your design should be adaptive to ensure perfect display on any device. To check adaptability, test your design on a tablet, smartphone, and computer: this way you can adjust the display of elements in the interface and understand what and where to improve. Make sure the elements are not overlapping and are scaled correctly.

Platform Conformance

Research iOS and Android operating system guidelines. A guideline is a set of rules that determine how mobile apps are designed within an operating system. The iOS and Android systems have recognizable elements that users expect to see, so the guidelines help to create optimal UX and UI. Also, it will speed up the development process and reduce bugs.

Tools for Designing for Mobile Devices

As for the most popular tools designers use to implement solutions for mobile devices, we can consider the next four.

Figma 

Figma is an application for all kinds of graphical works: from creating website layouts to developing mobile interfaces and prototyping. Its biggest advantage is an opportunity to work directly in a browser, allowing access to projects from any computer or platform. You don’t have to buy multiple licenses or install the software. Another plus of the application is the collaboration feature that allows simultaneous changes to the project design by several users without the need to upload files locally.

Adobe XD

XD is designed from scratch to meet the requirements of modern UX/UI design with many features not available in other graphic applications. It solves the main problem that competitors can't cope with: it provides interaction with non-static elements and allows you to implement thoughtful dynamics on the page. Adobe XD is ideal for vector UI design, wireframe modeling, implementing engagement with interactive elements, and prototyping.

Sketch

Sketch is a simple vector tool. Designers and front-end developers use it to create UX/UI components. Sketch is simple and easy to learn, has an intuitive interface, and offers cross-platform design tools. It has a preview feature to see how the project will look on different devices. It has many good plugins and resources, plus some useful functions for working in the cloud.

InVision

InVision is a versatile design tool that focuses on maximizing UX for apps. It can be used to create automatically customized interactive prototypes for different devices. InVision Studio has tools for working with vector drawing, interactive design, and built-in animation. The application can be installed on macOS and Windows.

Mobile Application Design Process

UI UX mobile app design is a complex process that requires a thorough approach to ensure it is visually appealing and compatible with various devices and operating systems. You also need to make sure it’s handy for both experienced users and newcomers and meets modern trends in app design. So, what are the stages of mobile design?

1. Gathering data and design requirements. Research is a crucial part of the design effort, guiding the development of a product concept that accurately defines the market niche, functionality, monetization, and usage scenarios. 
2. Planning the architecture and navigation of the application. UX specialists create architecture based on application usage scenarios, ensuring navigation and consistency. This design stage is crucial for the end-user, as it directly affects the app's navigation and overall user experience.
3. Development of prototypes. Mockups are created for prototyping a mobile application, allowing for easy modification and identification of best solutions. This process involves discussing the architecture with the team and client, and later involving a team of developers to evaluate the technical design.
4. Testing the prototype. Interactive prototypes allow testing the app design to ensure it is suitable for the target audience, allowing for detailed feedback and understanding of user behavior patterns. This stage of development helps identify non-obvious patterns and improves the product's overall functionality.‍
5. Final refinements and development. Next, the agreed prototype is handed over to designers to make the product more attractive, refine the styling, and improve small user interactions, taking into account the final UI of a product. The final design is passed to developers who do the technical part.

These days, Fintech is becoming one of the world's fastest-growing industries. Every year, the number of new Fintech startups increases. In 2024, more than 13,000 such enterprises were recorded in the Americas.

Financial technologies include online banking applications, lending platforms, trading platforms, and robo-advisor apps for investing and budget planning. All these innovations demand top-notch Fintech solutions to serve customers, so aspiring Fintech startups need to find a talented team that can build an advanced product.

Key considerations when hiring

Before hiring a FinTech development company, it’s crucial to ensure the specialists have all the essential hard and soft skills. This way, the Fintech application project will have more chances to succeed. So, to hire reliable developers for your project, you need to understand the essential compliance requirements, which you will need to check. 

What are the must-have competencies of web development companies for Fintech?

• Technical knowledge. The company's developers must be well-versed in all the necessary coding languages, frameworks, technologies, and security norms. 
• Background in your niche. Check if a company has a portfolio of projects related to the financial field. 
• Familiarity with applicable finance legislation. The company must know industry norms such as PCI DSS and GDPR.
• Social skills. Seek a team that is able to ensure transparent communication, flexibility, well-organized teamwork, and attention to detail.

Experience in FinTech

Familiarity with the industry is obligatory for financial services development because the specialists must comprehend the main finance principles. A deep understanding of monetary standards and risk management allows developers to craft solutions that meet the niche requirements. Look for a company that has worked on apps or websites for mobile banking, budget management, cryptocurrency wallets, or other products related to Fintech app development. 

Technical Expertise

First of all, make sure the tech specialists know the necessary programming languages. For instance, frontend development for Fintech may require knowledge of JavaScript, libraries and frameworks such as React.js, adaptive and cross-browser layouts, as well as principles of responsive web design and great user experience. At the same time, Python paired with Node.js may be useful for backend development for Fintech.

Secondly, developers must ensure the product's security. To achieve this, they must understand finance APIs and data encryption protocols. Similarly, implementing secure coding methods and following best practices are critical to providing data security. Additionally, expertise in cloud and blockchain technologies can be vital for the safe and reliable launch and scaling of Fintech products.

In many cases, especially for lending platforms, a key functionality is digital credit scoring — the ability to assess a user’s creditworthiness based on real-time data automatically. Implementing such systems requires backend development expertise and experience working with financial scoring models, third-party data providers, and data compliance protocols. A development partner with proven experience building custom scoring logic can help you avoid regulatory risks and launch a more competitive product.

Security and Compliance Knowledge 

Fintech solutions must meet the latest regulations and standards for user data security. Since Fintech startups and online banks carry sensitive customer data, they are often victims of cyber attacks. That’s why there are legal regulations aimed at the safety of clients and ensuring secure accounting transactions. So, to get secure Fintech development services, check if a company has relevant experience and understanding of the best practices in data protection along with industry norms such as PCI DSS and GDPR.

Communication and Collaboration

Effective communication is crucial for successful Fintech website development. A simple and streamlined interaction provides quick response, the ability to adjust tasks quickly, and full transparency of their implementation. Also, the tech team members must evolve their problem-solving skills, be adaptable, and demonstrate excellent collaborative skills. The last thing can be reached only by an experienced provider, so you should assess the management style in a company.

Research Potential Partners 

Before hiring a Fintech development company, conduct research on your own. A company must have a website providing all the information about its expertise, portfolio, and contact details. Besides, don’t forget to check customers’ testimonials to determine the quality of the services provided. Likewise, case studies of Fintech projects will best demonstrate a company’s expertise and outcomes achieved. 

Develop a Request for Proposal

When you already have a candidate for possible cooperation, the next step is to write a project proposal. Initially, you need to define the project's goals, target audience, desired functionality, and budget. This process will help your possible contractor fully understand your business demands and provide you with a personalized offer.

Conduct Interviews

While conducting a technical interview, ask detailed questions about the development process to check your possible contractor’s skills. Secondly, the organization's leadership style and structure should be analyzed. Inquire about any cross-functional initiatives the company has worked on.

It’s also important to find out who is on the team. In addition to the usual members of a tech team, such as a technical lead, developers, and QA testers, there should also be an expert who works on UI/UX design for Fintech. And, of course, don’t forget to ask about their previous experience in the niche and evaluate their grasp of your business needs and vision of the product.

Portfolio Review

When selecting a software development company, experience is a key consideration. And the easiest way to assess it is by checking the portfolio. Companies that have been on the market for a while usually have numerous projects. However, you need to pay the strongest attention to those connected to the Fintech industry. Check for mobile banking apps, home loan calculators, or trading tools technologies to make sure their design, usability, and the achieved results are close to your goals and needs. 

Conclusion

Developing a Fintech product is not an easy task. Besides the fact you need to retain customers by providing an outstanding service, you also have to worry about things like regulations and data security. That’s why it’s essential to learn how to recruit decent Fintech development specialists. By following the clues given above, you will be able to find suitable candidates.

Single-page applications (SPAs) have earned a strong position in demand long ago. Such apps have one page where most information remains unchanged, and only its parts are updated when a user interacts with them. 

Maybe, you don’t know precisely what they are. However, you probably use them daily. Most social media, Gmail, and other programs are single-page apps. They are quickly adopted thanks to their fast load times and user-friendliness. 

As for React, it is quite a favored instrument for SPA web development. Programmers can build SPA’s components with React to ensure their scalability, reuse them with few configurations, and refresh them instantly without manually reloading a page. Besides, React solutions are optimized for SEO while delivering high flexibility thanks to the Virtual DOM. 

What Are React Single Page Applications (SPAs)? 

SPAs consist of one HTML page. To access it, you make a one-time connection and then – load and modify data without refreshing an entire page. Only the blocks engaged in the interaction process are updated while other page elements remain unaffected.

A clear illustration of a one-page application is Google Docs. While reading a text, you scroll through sheets, but the top row with the menu and the left panel with captions stay put. Whatever changes you make, certain things stay untouched.

React is very common for SPAs because of its convenience — it speeds up the programming process significantly. Also, note that it is not a framework, it’s a library. The main thing in it is the components as they represent particular items on a page. Each one of them contains the entire set of data and methods needed for work.

React allows you to save the state of the elements. This makes them isolated and self-contained. This feature, in turn, provides developers with the ability to reuse the elements as needed. Specifically, the same element can be applied to another page or parts of the website as many times as you want. This way, a developer doesn't need to re-write a significant part of the code. Therefore, the absence of complex dependencies between elements simplifies troubleshooting.

Pros of React SPAs

Why do giant companies like Meta choose React SPAs? It becomes clear after looking at its main advantages: 

• Versatility. SPAs can be used from any device that has access to the Internet. 
• Accessibility. There are no problems with сompatibility, as well as memory limitations, capacity, or installation time.
• Enhanced usability. These apps are straightforward and enjoyable to operate.
• Better responsiveness. It can be ensured thanks to the high speed of data load.
• Ability to process large volumes of data. The device's memory does not limit the processing power of an app and the volumes of data it operates.
• Code reuse. React allows developers to reuse parts of code as often as needed in the same app. 

Let's look closely at the main merits of React SPA development. 

Enhanced User Experience (UX)

The primary advantage of a single web page application is immediate data update, resulting in a smooth sensation from using and improved responsiveness. Since SPA doesn't have to implement full-page reloads during use, the contents of a page refresh very quickly. The program only needs to connect to the server at the start, and then simply loads the necessary segments as a visitor needs them. In a single-page app, everything works quickly after the first load and doesn’t keep users waiting. 

Improved Developer Efficiency

Programmers who use React receive a lot of tools that simplify the assembling of the single-page application architecture. Moreover, React allows reusing code in software architecture to speed up the work. For instance, if you decide later to evolve a one-page app into a full-featured multi-page application, you’ll be able to reuse about 30% of the code instead of writing everything from scratch. Plus, it will help your startup save time and reduce costs.

Rich Interactivity

React is a freely accessible framework library that has a JSX (JavaScript XML) compiler with a focus on the users’ comfort as it provides prompt rendering. Thus, by utilizing React, you can create a UI-centric product which is common to SPAs that should have fluid interfaces, rapidly responding to the actions of users.

Cons of React SPAs

Surely, React SPA development has its drawbacks. Otherwise, every app would be written using this framework. 

The most important cons of these apps are:

• Lack of SEO optimization. The whole point is in the structure of such applications, which consist of just one page.
• Longer initial loading time. Since all user-side data of the application must be loaded during initialization, this can cause unpleasant delays for users.
• The client-side routing challenges. React may not be the best choice for creating applications with complex business logic and data routing.

So, let’s check each of them in more detail.

SEO Challenges

Single-page applications are quite problematic to index because not much text can be recognized by search robots. At the same time, you can’t put all the keywords on one page because it will look weird and lead to spam problems. What's more, the page will have only one URL.

You can eliminate this issue by resorting to server-side rendering. It's a way to render a one-page application on the server side. The app is still one-paged, but the main work is done on the server. The application receives a finished page with the required SEO elements from the server immediately after its initialization. However, due to the complex introduction of this technique, the cost of SPA development might be higher.

Complexity for Large Applications

Managing complex states and data traffic can be a problem in large SPAs. That’s why using React SPAs relates mostly to projects with rather limited functionality. At the same time, if applied skillfully, this library can still be useful when creating large projects – evidence of this is the digital giants that actively use it in the development of their services and applications. 

Initial Load Time

With React’s ability to load all content during initialization, people can wait a lot when opening a SPA first (in comparison to other websites). However, after initial loading, all other data will be pulled up automatically, and there will be no issues with delays in provisioning page content. 

Code splitting solves the problem of slow app loading by reducing the volume of data sent on the first session. Rather than uploading the entire code at once, users do it only with the parts that they need right now. This, in turn, facilitates the coding procedure.

React SPAs vs Traditional Multi-Page Applications (MPAs)

These kinds of apps are paralleled and characterized as competitors. However, multi-page applications (MPAs) are unlikely to lose the race because each alternative works for certain products and commercial pursuits. 

Let's look at the core strengths of each application type:

As you can see, each application type has its drawbacks and advantages. So, when choosing between them, come from the specifics and tasks of your company. 

What kind of companies should pay attention to one-page solutions?

• Products that run on a captivating platform with low data volumes. SPA is commonly applied to SaaS platforms, social media, and private communities. Some examples include Grammarly, Netflix, and Slack.
• Startups focused on usability. Single-page apps allow you to create an easy-to-use and intuitive interface that attracts the eye and encourages customers to explore the product. 
• Startups planning to go big. Later you can reuse some of the code of your single web page application. This helps reduce the time and expense involved in developing new, full-fledged digital solutions.
• Businesses for whom SEO is not a key metric. If your company doesn't require to be ranked high on Google from its first launch, to successfully implement your idea, SPA is right for you.
• Companies with their own APIs. You can build a one-page application based on a pre-built API.

Conclusion 

Today, we see that one-page applications gradually replace classic applications and begin to play an important role in the construction of large-scale web systems. Now, these apps are everywhere, and we use them every day without noticing it. Moreover, the big players in the app market already use SPAs.

What are the rewards of single-page applications? They are pretty speedy, don't keep visitors on hold, and generally improve their experience when dealing with the solution. in turn, overall consumer comfort has a direct impact on conversion rates and profits.

Still, SPAs are not ideal for all startups. But for those seeking a dynamic, high-speed, and lightweight digital solution, SPAs are an excellent choice.
