When you publish your app on the App Store or Google Play, you anticipate attracting a large number of downloads.
However, are you certain that your system can handle this load and operate smoothly and efficiently?
Don’t take unnecessary risks – ensure your app can handle high loads by testing its performance before release. Conduct tests under controlled conditions to identify and address performance issues in advance.

Ensure your app can handle high download loads by testing its performance before release
Stats don’t lie
Poor mobile application performance can result in negative user experiences, leading to low user engagement, increased uninstalls, and negative reviews.
This, in turn, can lead to reputational losses, decreased brand trust, and potentially lost revenue.
This, in turn, can lead to reputational losses, decreased brand trust, and potentially lost revenue.
Studies have shown that a one-second delay in mobile app load time can result in a 7% reduction in conversions and an 11% decrease in page views, which directly impacts a company’s revenue.
Additionally, nearly half of all users expect mobile apps to load within two seconds or less, with many abandoning apps that do not meet this expectation.
When you might need it
At PFLB, we offer a wide range of mobile testing services, including:
Software validation
We offer performance testing services to ensure that your mobile application can handle the load when it goes live in the store.
Continuous performance testing
It’s important to establish a testing process for each new release of your application, even if it has been tested before release.
This ensures that any performance issues are detected and fixed before they affect the user experience.
This ensures that any performance issues are detected and fixed before they affect the user experience.
Preparation for peak loads
We can help you prepare for peak loads that occur on sales days such as Black Friday, holidays, and advertising campaigns, to ensure that your application can handle the increased traffic without any issues.
What we could offer you
We provide comprehensive mobile app testing for both back-end and front-end aspects. Ensure your app runs smoothly across devices and under heavy loads.
Investigate back-end performance for load testing and address front-end issues for optimal user experience.
We generate a load with a specific number of users to test the performance of your app’s back-end.
We offer mobile app profiling with a focus on hardware resources consumption and other performance metrics including time to first byte. Our approach encompasses both manual and automated processes, such as headless browser testing.
Want to know how your system compares to competitors? Let’s run comparison tests and improve your product.
If you’re not sure where to look, we’ll check both the back-end and front-end for bottlenecks and eliminate them.

Sample report
You will receive a comprehensive report that summarizes all the issues we uncover, contains visualized metrics and recommendations on performance optimization.
Each case of resource overconsumption by the application will be detailed in terms of its business value, the responsible component, and the specific section of the system involved.
This way, you can identify which operation is using the most resources and pinpoint the component and code section responsible for the issue.
