Mobile Apps Testing Services for Speed, Security, Scalability

Recent data reveals that over 46% of mobile apps are uninstalled within 30 days of download. Poor quality is often to blame.

Is the app tested for real-world conditions like weak networks, session failures, and mobile disruptions?
Can it handle API changes, broken integrations, and hidden security flaws without failing?
Is it secure, compliant, and resilient against data risks and system failures?

At CalibreCode, we specialise in comprehensive mobile app testing services designed to enhance your app's performance across all devices, networks, and operating systems. Our approach focuses on Reducing Failure Rates, Boosting User Retention, and Maximising Revenue.

Explore CalibreCode solutions to ensure your app stays installed and becomes essential to your users' daily lives.

Mobile App Testing: Expand Device Coverage, Boost Speed, Drive User Satisfaction, Maximise App Efficiency

Partner with CalibreCode to confidently navigate the complexities of mobile app testing. Our testing strategies are backed by practical insights, ensuring your app meets user expectations in today's competitive market.

Real users don’t experience apps in perfect conditions. A test might pass in controlled environments, but real-world chaos exposes flaws and UX hiccups that drive users away.

At CalibreCode, we focus on:

Real Device Testing: We test on real devices in actual conditions (low battery, weak networks, background apps running).
Network Chaos Testing: Ensure your apps survive 4G to 3G handovers, aeroplane mode toggles, or sudden connection drops.
Gesture & Interrupt Testing: We test real-world interactions (and some extreme ones), such as when users swipe, pinch, tap rapidly, or receive a call mid-payment.
Performance Under Load: We test for heavy traffic, slow animations, memory leaks, and overheating issues.

Our Capabilities

Mobile App
Functional Testing

Rigidly validating core functionalities, APIs, and third-party integrations ensures that features work as expected. Testing covers user interactions, input scenarios, and expected outputs across various mobile platforms, from iOS 15, 16, and 17 to Android 12, 13, and 14.

Mobile App
Compatibility Testing

Verify that your app runs flawlessly across different devices, screen specifications, OS versions, and network conditions, including Wi-Fi, Ethernet, 4G, and 5G, without crashes or inconsistencies.

Mobile App
Performance Testing

Validate your app’s speed, responsiveness, and stability under different conditions, including high traffic loads, background processes, and varying device capabilities. Analyse performance metrics such as loading time, memory consumption, and CPU usage.

Mobile App
Security Testing

Shield your app against vulnerability assessments by implementing manual penetration testing, analysing data encryption, and conducting compliance checks to protect sensitive user information.

Mobile
Test Automation

Enhance testing efficiency and accuracy using automation tools to execute repetitive test cases across multiple mobile platforms, reducing time-to-market

Mobile App
User Experience (UX) Testing

Ensure the app delivers an intuitive and engaging experience by evaluating usability and user behaviour across different devices and screen sizes.

Interruption
Testing

Test app behaviour under real-world interruptions, including incoming calls, notifications, low battery, and network loss.

Mobile
Localisation Testing

Validates app translations by ensuring the accuracy of UI text, error messages, and notifications without formatting issues. It also verifies cultural relevance by assessing date formats, currencies, languages, and right-to-left (RTL) UI rendering to ensure seamless region-specific adaptability.

Mobile
Compliance Testing

Ensure compliance with W3C mobile web standards and Human Interface Guidelines (HIG) for a smooth and standardised user experience.

Mobile
Game Testing

We validate by ensuring accurate object placement, stable tracking, intuitive controls, and seamless performance across devices and environments, including gestures, surface detection, battery efficiency, and frame rate optimisation.
