Mobile App Testing Services
Ensure flawless performance with our mobile app testing that goes beyond standard checks. Using real devices and advanced automation, we ensure your app meets requirements, performs smoothly, and delivers a seamless user experience.
Why You Need Mobile Applications Testing Services
Missed bugs and defects
Without a structured QA process, critical bugs may slip into production, leading to poor user experience, instability, and negative feedback.
Compatibility limitations
Apps not tested across multiple devices and OS versions may not work properly for all users, reducing accessibility and limiting market reach.
Increased time and costs
Fixing issues after release is costly and time-consuming. Early QA helps avoid delays, budget overruns, and repeated development cycles.
Low ratings and reviews
Bugs, crashes, or poor usability often lead to negative user reviews, harming your app’s reputation and reducing visibility in app stores.
Our Mobile Application Testing Services
We combine advanced technologies with hands-on testing to assess every critical aspect of your mobile app. Each testing method targets a specific area to keep your app competitive, reliable, and high-performing. Our mobile testing services include:
Functional testing
Functional testing is a core part of mobile app testing services. QA engineers interact with the app just like real users, testing everything from basic actions like tapping buttons to complex, app-specific scenarios. This process ensures all features work as intended and helps identify issues that need to be resolved before release.
Performance testing
During performance testing, the Requestum team evaluates how your app behaves under various conditions. We assess the responsiveness, speed, and reliability of the app across different loads, network environments, and device types. The goal is to ensure your app remains fast, reliable, and consistent no matter the environment or demand.
Compatibility testing
Mobile compatibility testing ensures your app functions smoothly across a wide range of devices, operating systems, screen sizes, browsers, and versions. Our QA engineers test core features, responsiveness, and visual consistency to ensure your app delivers a seamless experience on any platform and device your users choose.
Usability testing
Our experts conduct thorough usability testing to uncover issues that may hinder user satisfaction. By analyzing user flows, interactions, and design elements, we identify areas for improvement and provide actionable recommendations. The goal is to help you create an intuitive and engaging mobile app for your end users.
Accessibility testing
Accessibility testing evaluates whether your application meets established accessibility standards and guidelines, ensuring it can be used by individuals with various impairments. Our team checks key elements to identify and fix barriers. This helps create an inclusive user experience that prioritizes equal access for all users.
Security testing
We perform security testing to protect your mobile application from unauthorized data access, cyberattacks, and potential information leaks. Our QA engineers simulate real-world threat scenarios to identify vulnerabilities. The result is a more secure and resilient mobile solution that keeps user data safe and your reputation protected.

Our Approach to Mobile App Testing Services
Our mobile application testing service is built to ensure every critical aspect of your app is thoroughly examined. Once we understand your goals and the specific features of your product, our QA specialists create a tailored, step-by-step testing plan. Typically, the process includes five key phases. Let's look at them in detail.
-
1Planning
During the planning phase, our QA team dives deep into your product’s functionality, technical specifics, and requirements. As a reliable mobile testing company, we define the test scope, outline the roadmap, and build a tailored strategy to guide the entire QA workflow, ensuring alignment with your expectations from day one.
-
2Designing tests
Our specialists prepare detailed test cases, checklists, and test data to cover real user scenarios. As a seasoned mobile app testing company, we also set up a testing environment that mirrors actual usage conditions - different devices, screen sizes, and OS versions to make sure the results reflect real-world behavior.
-
3Running tests
Our QA engineers simulate real user interactions, evaluating performance, usability, functionality, and security. This is where the testing of mobile applications reveals bugs, inconsistencies, and friction points that could impact the user experience. By catching these issues early, we help ensure your app works well.
-
4Stabilization
While developers implement code fixes, our QA engineers continue to perform a series of validation checks. These tests ensure that all previously reported issues are resolved and no new bugs have been introduced during recent updates. The goal of our mobile testing outsourcing services is to confirm that the app is stable and polished.
-
5Delivery
After all tests are passed and fixes are confirmed, your app is ready to launch. But the work of our mobile testing outsourcing company doesn’t stop there. We continue to monitor feedback, review tickets, and support ongoing updates if needed. We help you track quality, resolve any post-release issues, and prepare for future iterations.

James Hodson
CEO, MySyla
Requestum works more efficiently during a war than most other teams work in peacetime. The quality of development work is excellent on all fronts. Despite setbacks with the team needing to move around the country to stay safe, air raid sirens, and Internet outages, the team has never missed a deadline or gone a day without finding a way to communicate. Requestum genuinely cared about making sure the final product was exactly what was needed. The team improved the features in ways that we could never have come up with ourselves. They obviously enjoy working together, and have created an excellent team spirit and work ethos.

Requestum was always accessible and ready to discuss new ideas. Every suggestion that i have made during the project was carefully considered, and went through feasibility pipeline which worked perfectly for my platform.
