Ensures seamless Android & iOS app performance with expert mobile testing, real-device checks, and automation users can trust.
Mobile app testing checks that your iOS or Android app installs, works, stays fast and stays secure on the phones, tablets and watches your users carry, on real networks and through real interruptions. We test every layer on real devices, and report every bug with video and device logs.
Our Functional Testing as a Service for mobile apps ensures reliable performance, responsive UI, and consistent behavior across devices, OS versions, and screen sizes. We validate gestures, integrations, notifications, and background processes under real-world conditions so your app not only works — it delights.
✓Deliver a smooth user experience across devices, OS versions, and networks.
✓Detect and resolve bugs early in the development lifecycle.
✓Ensure compliance with Apple and Google app store guidelines.
✓Launch high-quality mobile apps that boost ratings, retention, and ROI.

[ Mobile app types ]
Every kind of mobile app fails in its own way
A native iOS app gets rejected at review. A Flutter app behaves differently on Android. A watch app loses sync with the phone. We start with the risks that belong to your type of app, and test those first.
01
Native iOS apps (Swift)
Apps built for iPhone and iPad with Apple’s own tools.
We test first
✓Behaviour across iPhone models and iOS versions
✓Permissions, Face ID and privacy prompts
✓App Store review rules
02
Native Android apps (Kotlin/Java)
Apps built for Android phones and tablets.
We test first
✓Different makers, screens and Android versions
✓Permissions and background limits
✓Google Play policy and release checks
03
Cross-platform (React Native, Flutter)
One codebase that ships to both iOS and Android.
We test first
✓Features behaving the same on both platforms
✓Native modules and plugins
✓Speed on older devices
04
Hybrid apps (Ionic, Capacitor, Cordova)
Web code running inside a native app shell.
We test first
✓How the in-app browser renders on each OS
✓Camera, files and other device features
✓Scrolling, gestures and speed
05
Mobile web / PWA
Websites and web apps used in a phone’s browser.
We test first
✓Mobile browsers and screen sizes
✓Install, offline and push behaviour
✓Touch, keyboard and form input
06
Wearable apps (Apple Watch, Wear OS)
Watch apps and the phone apps they pair with.
We test first
✓Sync between watch and phone
✓Small screens, glances and complications
✓Battery use and sensors
07
Tablet / iPad apps
Apps designed for larger touch screens.
We test first
✓Split view, multitasking and rotation
✓Keyboard, trackpad and stylus input
✓Layouts that use the larger screen
08
Apps with in-app payments / subscriptions
Apps that sell items, upgrades or subscriptions inside the app.
We test first
✓Purchase, restore and refund flows
✓Renewals, trials and plan changes
✓Store billing rules and receipts
[ Platforms we cover ]

✓Both storesIn-app purchases and subscriptions work in sandbox
✓App StoreApp Privacy labels and App Tracking Transparency prompt
✓App StoreTestFlight build tested on the latest iOS and recent iPhones
✓Google PlayData safety form, target API level and content rating
✓Google PlayPre-launch report clean and staged rollout planned
✓Both storesCrash reporting and analytics on, with rollback plan agreed
Our device lab
Real devices first, device clouds for breadth
Core journeys run on real iPhones, iPads and Android phones in our team’s hands. For wider coverage we add device clouds such as BrowserStack and Sauce Labs, and use emulators and simulators for fast feedback during development.
Sixteen testing types, sorted by the layer they protect
A mobile app has more to go wrong than its screens. We group our testing into five layers, so you can see exactly which part of your app each test covers.
With the right mix of manual and automated testing, we help apps perform better, scale faster, and win user trust.
01
Unit Testing
Validate individual app components for logic and stability.
02
Integration Testing
Ensure modules, APIs, and third-party services function together
03
System Testing
Confirm full app builds perform under expected conditions.
04
Regression Testing
Ensure new updates don’t break existing functionality.
05
UI/UX Testing
Check design consistency, gestures, and responsiveness.
06
User Acceptance Testing (UAT)
Simulate real-user behavior and business goals.
07
Compatibility Testing
Validate across OS versions, devices, and screen resolutions.
08
Responsive Testing
Verify layouts in both portrait and landscape modes.
09
Usability Testing
Identify friction points and optimize user journeys.
10
End-to-End Testing
Cover the complete lifecycle from install to uninstall.
[ Devices & conditions ]
The right devices, in the conditions your users face
There are thousands of phone models. We read your analytics and store data, split devices into three tiers, then test them on real networks and through real interruptions.
Tier 1
Full testing
The device models and OS versions most of your users have. Every test case runs here.
Tier 2
Key journeys
The next group of devices. Sign-up, payments and your other critical flows run here.
Tier 3
Smoke check
Older or less common devices. A quick check that the app installs, opens and core actions work.
Real devices, cloud labs and emulators
✓Real iPhones, iPads, Android phones and tablets for the checks that decide a release
✓Cloud device labs such as BrowserStack, Sauce Labs and Firebase Test Lab for wider coverage
✓Emulators and simulators for fast feedback early in a sprint
✓Apple Watch and Wear OS watches paired with their phones
Real-world conditions we recreate
▸Slow, unstable and offline networks
▸Switching between Wi-Fi and mobile data
▸Incoming calls and notifications
▸Low battery and power-saving mode
▸App sent to background or closed mid-task
▸Rotation, split screen and dark mode
▸Permissions denied or changed later
▸Low storage and older hardware
