Mobile Application Testing Services

We test on the same mobile devices as your users!

Start a Project

Mobile testing will ensure that native, mobile-web, or hybrid apps meet any requirements. These services contain a huge number of checks on multiple devices, screen resolutions, operating systems, internet connections, and more.

Usually, getting an app live on Google Play takes a few hours. For the App Store, it’s a few weeks. We can’t really say how long the errors will influence current and new users while the apps are in the review process.

Testing mobile applications has saved more than one app from terrible reviews and audience loss.

The key to making your brilliant idea successful is to use a high-quality mobile testing service. That is why you need the help of an experienced mobile testing company, one that knows all the specifics and bottlenecks of the process.

Testing of mobile applications has a high priority because the mobile application market is growing every year. Our company has hundreds of case studies for testing mobile applications in various industries. Testing of Android applications, iOS applications, progressive web applications - we can cover all this with our automation and manual testing teams.

Instant access to a huge number of real mobile devices

No pain managing your own device set

The stable and structural testing process

Highly experienced mobile testing engineers who knows the specifics

Avoiding violent backlash caused by defects

Improving the usability of your app

Mobile Application Testing Services We Provide


Automation testing

Mobile Automation Testing increases the efficiency of testing and reduces time to market of the application.


Manual testing

Need for coverage all specific test cases which can't be covered by automated tests.


Mobile Application testing

From the analysis of requirements through test planning and execution — to reporting issues and maintaining solutions.


Functional testing

During functional testing of mobile application, we ensure that the application meets the requirements using a deep understanding of its logic to vastly improve product quality.


Usability testing

It is essential to ensure that the application is as comfortable as possible for the end user.


Compatibility and Cross-device testing

Device fragmentation testing is performed on various platforms, form factors, screen resolutions, sizes, etc.


Performance testing

Mobile application performance testing define an optimal response time from the server; detect memory usage and bandwidth issues.


Localization testing

In the process of localization testing, special attention is paid to the languages supported by the application, accuracy of translation of various interface elements and correctness of date/time settings, etc.


Web testing

Testing of your application on real mobile devices to make sure your application works well on various browsers and screen sizes.


Connection quality

The app should also be stable and shouldn’t depend on connection speed or state (Edge, 3G, LTE, Wi-Fi, poor signal, bad connection, network interruption, etc.)



Ensure that incoming calls, low signals, battery charging or dead, rotation, Bluetooth on/off, voice commands, etc. can’t affect the application working as well.



Testing is not limited to searching for errors. We also provide recommendations for UX and UI improvements and more. We clearly understand what will be convenient and powerful for an end-user — and what has to be improved.

Popular Questions

What tools/services would be useful when performing mobile application testing?

Because of the variety of devices, cross-platform testing is essential. Even if you do not have enough real mobile devices, you can use cloud services for cross-platform testing, such as BrowserStack, SauceLab, AWS Device Farm.

Android Studio and Xcode are the best choices when it comes to emulators and recording device logs.

Why is it important to test Mobile Application updates?

Developers can forget about migrating data from older versions to the updated one, causing critical errors, deletion of user purchase data, or affecting the parts of the application that worked by fixing other bugs. Without proper testing, you risk making your users think about whether they should use the app, or leave poor reviews.

Should I use real devices or emulators?

Using physical devices lets you get a feeling for the app, how it performs on real hardware, and all the factors that may contribute to it working or crashing. App emulators don't allow for a true user experience. Using a full-sized keyboard with mouse is a completely different experience than physically navigating the mobile application via touch and gestures.

The biggest reasons why testing on real devices usually leads to better results:


User experience and usability

You cannot emulate how the app is used in real life. How does it look when you are under the sun? Does the interface fit with swipes?



Emulators can’t show how an app reacts during phone calls, receiving messages, etc.


Memory Related Issues

Real devices multitask unlike emulators, so a lot of processes and applications are performing simultaneously. They don't represent the real state of the app performance.


Display related issues

Separate from resolution, there are issues with the quality of display in general. There might be mismatching between the designed UI and how it looks on a real device.


Battery related issues

Emulators can’t test the power efficiency of your app. What if it kills your device in a couple of hours?


Customization and Platforms

You need to ensure that your app isn't influenced by any other pieces of software on the device

Which checks should be performed for the security of mobile applications?

Security testing is necessary to guarantee the security of information and customers. The following checks must be performed:


Ensure the requirement of a strong password


The security system must not allow access to other users credentials


You must be sure that financial information is reliably protected


Ensure that access to private user content cannot be obtained to bypass authentication


Make sure that SQL/CSS injections can't harm the application, destroy the user data, or make it public


Check that issue with buffer overflow can't lead to a loss of the user information

How is the testing of a mobile application organized?

Mobile application testing is different from testing desktop or web apps. Before starting, you should determine the type of mobile app (mobile-web, native or hybrid) which helps you to choose a strategy. Also, you should choose the devices type (real, emulators or simulators, as well as cloud testing services). Each of the types has its advantages and disadvantages, but competent specialists will always help you in choosing the right one. Then you should understand when to choose manual and when to use automated testing.

Testing mobile apps starts with the documentation phase, which is the foundation for future work. Some testing types usually included on initial stages are functional and UI/UX. As soon as the QA engineer is convinced that the GUI completely coincides with the layouts on different devices, with different screen diagonals, an important stage begins - testing for compatibility. When the application is perfectly compatible, we can safely move on to testing the performance and security.

The latest stage is Certificate Testing. There are certain rules for organizing an installation file (.apk) and rules for applications design for each application store. Certification testing verifies that the app meets the requirements of the most popular stores like Google Play and App Store.

What trends should be tracked to improve the testing process?

These are strict rules from Apple and Google describing the process of publishing in app stores. It will be useful practice to track them despite in general, but they are quite trivial.

Also, Google and Apple provide design guidelines. Following them is necessary. Keep track of the direction each platform is moving. This will give you a better understanding of users’ expectations and the opportunity to increase the quality of UI and UX testing.
