Direct answer / 01
What is mobile app testing?
Mobile app testing is the process of verifying that an iOS or Android application works correctly across the range of devices, operating system versions, screen sizes and network conditions its users actually have. It covers functional behaviour, installation and upgrade paths, performance and battery impact, offline and poor-connectivity handling, permissions, and store-submission requirements. Because a bad mobile release can't be hot-fixed instantly the way a website can, mobile testing carries more weight per release than any other channel.
Coverage
What we test on mobile
Functional and regression testing on a device matrix chosen from your own analytics
Automated iOS and Android suites in Appium, XCUITest and Espresso
Install, upgrade and migration paths from previous app versions
Network conditions: offline, flaky 3G, airplane mode and network switching
Performance, memory, battery drain and cold-start time
Permissions, push notifications, deep links and background behaviour
Store-readiness checks against App Store and Google Play requirements

Devices
Real devices, not just emulators
Emulators are fine for fast feedback loops; they are not where you discover that a specific Android OEM breaks your camera flow. We run the critical suite on real hardware, on the device and OS combinations your analytics say your users actually carry.
The device matrix is agreed up front and reviewed each quarter, so coverage tracks your real audience rather than a generic top-ten list.

Mobile app testing verifies that an iOS or Android application works correctly across real devices, OS versions, screen sizes and network conditions, covering functionality, performance, upgrades, permissions and store requirements.
Both. Emulators give developers fast feedback during the build; the critical regression and release suites run on real hardware, because OEM-specific behaviour only shows up on the real thing.
From your own analytics. We take the device and OS distribution of your actual user base, add any device your support team sees disproportionate complaints about, and agree a matrix that covers the large majority of sessions.
Yes — Appium for cross-platform suites, XCUITest for native iOS and Espresso for native Android, integrated with your CI so each build is verified automatically.
Always. Upgrade paths are where data-migration defects live, and they affect your entire existing user base rather than new downloads.
Yes. We check builds against current store review requirements — permissions, privacy declarations, accessibility and content policies — before submission, and help diagnose rejections when they happen.
