Mobile QA Across Every Device That Matters
iOS and Android testing on real devices — functional testing, visual regression, and performance profiling across the device fragmentation that breaks mobile apps.
You might be experiencing...
Mobile QA is a 5-day sprint that tests your iOS and Android apps across the real devices your users actually have — not the one device on your developer’s desk.
The Device Fragmentation Problem
Mobile apps break in ways web apps don’t. Screen sizes, OS versions, manufacturer customisations, memory constraints, and network conditions create a matrix of environments that is impossible to cover with manual testing on a handful of devices.
The result: your app works on the devices your team owns and fails on the devices your users have. Those failures become 1-star reviews, support tickets, and churned users.
How We Test
Analytics-driven device matrix — we don’t test on random devices. We analyse your user analytics to identify the exact device/OS combinations that matter, weighted by user share. Your testing budget goes where your users are.
Functional testing — every critical user journey is tested on every device in the matrix. Login, onboarding, core workflows, payment flows, and offline/reconnect scenarios — tested systematically, not ad hoc.
Visual regression — UI consistency is verified across screen sizes, orientations, and OS versions. We catch the layout breaks, font rendering issues, and responsive design failures that users screenshot in their 1-star reviews.
Performance profiling — app launch time, memory usage, battery consumption, and network resilience are profiled on representative devices. We identify the performance issues that only appear on older or lower-spec hardware.
Platform-Specific Testing
iOS — we test across iPhone and iPad models, covering the OS versions that represent 95%+ of your iOS user base. We test platform-specific behaviours: Face ID, haptic feedback, widget integration, and App Clip flows.
Android — the fragmentation challenge is greater on Android. We test across Samsung, Google Pixel, Xiaomi, and other manufacturers, covering the OS versions and manufacturer-specific customisations that cause Android-specific bugs.
Delivered in 5 Days
A complete mobile QA sprint — device matrix, functional testing, visual regression, and performance profiling — delivered in one business week with a prioritised bug list and reproduction steps for every finding.
Engagement Phases
Device Matrix & Journey Mapping
We analyse your analytics data to identify the exact device/OS combinations your users rely on. We define a device testing matrix weighted by user share and map your critical user journeys for each platform — iOS and Android may have different priority flows.
Functional & Visual Regression Testing
Systematic testing across your device matrix — functional testing of every critical journey, visual regression testing for UI consistency across screen sizes, and interaction testing for platform-specific behaviours (gestures, notifications, deep links, background/foreground transitions).
Performance Profiling & Report Delivery
Performance profiling on representative devices — app launch time, memory usage, battery consumption, and network behaviour under poor connectivity. Delivery of the complete Mobile QA Report with every finding, screenshot evidence, and prioritised fix recommendations.
Deliverables
Before & After
| Metric | Before | After |
|---|---|---|
| Device Coverage | Testing on 1-2 devices — covering under 30% of user base | Testing across 15+ devices covering 95%+ of user base |
| Platform Parity | One platform tested thoroughly, the other barely tested | Both iOS and Android tested to the same standard per release |
| App Store Rating Impact | 1-star reviews citing device-specific crashes and UI bugs | Device-specific bugs caught before release — rating trajectory improves |
Tools We Use
Frequently Asked Questions
Do you test on real devices or simulators?
Real devices via BrowserStack and Sauce Labs device farms. Simulators are useful for development but miss real-world issues — touch responsiveness, memory pressure, GPS behaviour, camera integration, and push notification delivery all behave differently on real hardware. We test on the actual devices your users have.
How much does Mobile QA cost?

Do you test React Native / Flutter cross-platform apps?
Yes. Cross-platform apps often have more device-specific issues than native apps because the abstraction layer masks platform differences. We test React Native, Flutter, Ionic, and native iOS/Android apps — our device matrix and testing approach adapts to your framework.
Can you set up automated mobile testing that runs on every build?
Yes — for teams that want ongoing automated mobile regression, we can set up Appium or Detox test suites integrated with your CI/CD pipeline during the sprint. This is an add-on to the core functional testing and is recommended for teams shipping weekly or more frequently.
