With the proliferation of mobile devices and operating systems, it is becoming more and more difficult to ensure the smooth work, high performance, utter security, and usability of mobile applications across all smartphones, tablets, and platforms. This makes mobile app testing compulsory since it evaluates the operation of apps from various angles – functionality, compatibility, user experience, security, etc. – to guarantee their reliability and effectiveness. Since 2010, DeviQA has served companies across diverse domains such as Healthcare, FinTech, Real Estate, Cybersecurity, Retail, AdTech, and others. This extensive expertise enables us to deliver top-notch mobile testing services that not only ensure excellent app quality but also streamline development processes.

Our Solutions For Your Mobile Application Testing Challenges

We understand the complexities of mobile application testing and offer tailored solutions to address your specific challenges. With our expertise and comprehensive approach, you can ensure the success of your mobile app in today's competitive landscape.

Device Fragmentation


Navigating the vast landscape of mobile devices and operating systems can be overwhelming. With users accessing applications on various smartphones, tablets, and across multiple platforms, ensuring seamless compatibility is a significant challenge.


Our mobile application testing services comprehensively tackle device fragmentation. We employ a robust testing matrix that covers a wide array of devices, operating systems, and screen sizes. This ensures your application functions seamlessly across diverse platforms so that every user can enjoy their experience with your app.

Rigorous Performance Testing


Performance glitches can be detrimental to user satisfaction. Slow loading times, crashes, or unresponsive features can lead to negative reviews and diminished user trust.


Our testing approach includes rigorous performance testing under real-world conditions. We simulate various scenarios to ensure your application withstands peak loads and works optimally even in unexpected circumstances. This enhances overall app performance and guarantees a great user experience.

Security Concerns


With the rising number of cyber threats, ensuring data security within your mobile application is paramount. The identification of vulnerabilities before app deployment is a critical aspect of the QA process.


Our mobile application testing services are based on cutting-edge security testing methodologies. We conduct thorough assessments to identify and address potential security loopholes. This ensures that your application is protected against potential threats, safeguards user data, and maintains trust in your brand.

Our Mobile Application Testing Services

Our team of expert mobile testers executes a wide range of testing types to guarantee the sky-high quality of your mobile applications. Here are the types of tests that our mobile application testing services cover:

Functional Testing

We meticulously assess all features of your mobile app to make sure they work as expected. From basic actions to complex workflows, we verify that all functionalities work flawlessly across various devices and operating systems.

Usability Testing

A great user experience is paramount. We conduct usability testing to gauge how intuitive and user-friendly your app is. By simulating real-world scenarios, we identify any usability issues and provide actionable insights to improve user satisfaction.

Compatibility Testing

With the multitude of devices and operating systems available, compatibility is a crucial aspect of mobile apps. Our compatibility testing ensures your app operates consistently across different devices, screen sizes, resolutions, and OS versions, delivering a seamless experience to all users.

Performance Testing

Speed matters. We rigorously evaluate the performance of your app under various conditions, including different network strengths and load capacities. By identifying and addressing performance bottlenecks, we optimize your app for faster response times and superior user experiences.

Security Testing

Secure protection of user data is non-negotiable. Our security testing scrutinizes your app for vulnerabilities and potential breaches. From encryption protocols to data storage practices, we check all security aspects to ensure the remarkable resilience of your app to security threats, safeguarding sensitive information.

Installation Testing

First impressions count. We ensure smooth installation and uninstallation processes across different devices and platforms. By verifying app installation procedures, we guarantee a seamless onboarding experience for users, minimizing installation-related issues.

Localization Testing

Your app should speak the user's language, literally and figuratively. We conduct localization testing to ensure your app's content, language, and cultural nuances resonate with diverse global audiences, enhancing user engagement and market penetration.

Regression Testing

As your app evolves, so do the risks of introducing new bugs. We systematically execute regression testing to detect any unintended defects introduced by updates or modifications, maintaining the overall integrity and functionality of your app.

Manual Testing

Our experienced testers meticulously explore your app's functionality, interface, and user experience, simulating real-world usage scenarios. Through manual testing, we uncover nuanced issues that automated tests may overlook, ensuring your app meets the highest standards of quality and usability.

Automation Testing

We harness the power of automation to optimize the QA procedure, expedite delivery schedules, and guarantee reliable testing results throughout various testing iterations.
