Fitness trackers and sports applications are in great demand at the moment. During the global quarantine, a lot of software for sports at home was created. Respectively, the functionality and interface of these sites and applications should be as convenient, understandable, and correct as possible. These components will determine whether users will continue to use this type of product or will look for similar applications from other developers. In order to make sure that these components are present, you should test your product.

Benefits of testing an app

  • Raising the rating among users

At present, requirements for mobile software usability are very high. Modern mobile applications must be very user-friendly and convenient. Otherwise, they will not be popular among users or may not be accepted to mobile software stores. Usability defects found during mobile testing get high priority. In this case usability testing is required.

  • Correct functioning of the product

For example, a timer is often used in fitness applications, pedometers, and physical activity tracks. It can be implemented in different ways – as a pop-up reminder, as an alarm clock, etc. Its incorrect work can mislead the user. Functional testing can solve this problem, because it aims to verify that the application works correctly according to the requirements. There is a need to make an evaluation of all the app functionality including fields validation, navigation, sharing feature, payment transactions, error messages, sound and video effects, etc.

  • Proper working of an app on different devices 

Ensuring software is compatible with various environments is very important. Given the constant development of the software market, it is impossible to create new applications with only one particular mobile/platform/browser/OS in mind. Millions of users use different devices and browsers to interact with software. To avoid system issues under different conditions, there is a need to perform compatibility testing.

  • No crashes during heavy loads

The capacity to respond quickly, to handle a large number of simultaneous users, and to remain stable under different loads defines the level of product performance. Performance testing facilitates the awareness that an application or any other product should meet all end-user requirements. The satisfaction of the users’ needs is precisely the key to the success of the developed software. Memory usage, battery consumption, CPU usage, loading time, app behavior in a multitasking environment, and in low-resource settings must be checked.

  • Correct processing of payments

The inability of the user to make a payment correctly affects the receipt of profit from the application and significantly affects the desire of users to continue using the application. The system capacity requires flawless integration with third-party software. Consisting of several integrated modules, every software needs checking with integration testing.

Real cases when testing has helped

Application for Weight Correction


It is an application that helps people lose weight by monitoring and tracking water balance and calorie intake. The application has the following features: calorie counter, daily activity tracker, pedometer and individual meal plan. 


Being cross-platform, the application required to be checked for compatibility capacity, but the customer didn’t have the necessary technologies and tools.

  • QATestLab checked the system operation and evaluated its compatibility to different environments due to available required equipment and devices. 
  • We verify trackers comparing the counted number of steps and calories. 
  • By testing, we ensured that the newly implemented features and functions did not affect the existing functionality. 
  • By testing the application and its usability, we made sure that the application was easy-to-use and people would face no difficulties during the use.

Application for Tracking Daily Activity


It is a mobile application created for tracking daily activity, sleep and number of steps made per day. The application can be used separately without any additional software and devices. However, the system supports the integration with third-party software including different wearable trackers and pedometers. 


After the application had been released to the market, end-users detected several issues that affected their application.

  • To check the system compatibility to different environments, we tested the system on several devices with different OS platforms. 
  • In order to check the synchronization of the system with the database and third-party trackers, we performed integration testing. 
  • All detected bugs were opened and processed in bug-tracking systems. 
  • We verified the operation of the system algorithms to count a number of calories and steps.

Application for Meditation


It is a customizable application for different types of meditation, which include breathing exercises, stories, courses, sound and music for relaxation and sleep. Customers can choose the type of meditation that matches their personal goals.


After the product had been released to the market, the customers started having problems with purchases in the application.

  • We analyzed the problem and performed complete testing of the payment process in the app. 
  • The project team made sure that no critical errors remained in the release version.
  • Additionally, we checked the application’s performance in order to check operation speed, scalability, and stability.  
  • Our team performed complete testing of the product functionality.


It is essential to consider that the users’ requirements may constantly change during software development and testing. Therefore, we should monitor and analyze these changes. In the future, this will only positively impact product promotion. Test your product at different stages of development. If you need help, QATestLab will be happy to help you with this. We deliver services on time and on budget.
