Appsierra's mobile app testing services
We perform extensive mobile testing services to ensure that your software works across all systems — from functionality and usability to performance, security, and compatibility — so every release feels flawless to your users.
Device strategy
How to select appropriate devices for your app's testing
Our team chooses the most appropriate devices, after taking into account the software characteristics, industry demands, and target audience, to maximize the resources available for mobile app testing services. As a provider of affordable software testing services, we ensure efficiency without compromising quality through a three-step process.
Examine hardware & software features
Examine market trends and gather statistics on essential device hardware and software characteristics.
Devices for testing selection
Devices are classified according to their priority, and we build a test roadmap from the most impactful coverage.
In-house QA
Our in-house mobile QA services
Since our inception, rigorous, continuous, comprehensive training and R&D have been our forte. All our professionals at Appsierra are up to date on the latest technologies, QA techniques, and tools in the mobile app sector, making us a full-cycle QA and testing company equipped to deliver high-quality, reliable solutions.

Share Knowledge
Gather and share our expertise and best practices.
Certify
Provide training and certification to our mobile testing engineers.
Real devices
Test on real devices
We use only genuine devices to test all elements of your mobile app's performance; no emulators or simulators are used. Real-world application testing shows how your app would function in the real world. We have a huge array of 200+ mobile devices and wearables — more than 120+ Android-compatible devices and 80+ iOS-compatible devices.
Dynamic environment
A dynamic environment that reflects your consumers' actual experience.
Reliable human logic
Control over the app and reliable duplication of human logic.
User interaction
Systematic analysis of real-world user interaction situations.
Scope
What does mobile app QA cover beyond functional testing?
The conditions the device imposes: fragmentation, interruption, network, battery and the store review that can block your release outright.
A mobile app is tested against a matrix nobody fully controls — OS versions users refuse to update, manufacturer skins that alter permissions and background behaviour, screen sizes and notches that reflow a layout, and devices under memory pressure that kill your process mid-task. Functional correctness on one flagship handset says very little about that matrix. Coverage means choosing a device set from your actual analytics rather than the newest hardware, and testing the lifecycle events that only mobile has: backgrounding, interruption by a call, permission revoked while running, process death and restore.
Network is the other axis. Apps are usually built on office wifi and used on a train, so offline behaviour, transitions between wifi and cellular, and slow or lossy links need deliberate coverage — including whether queued actions replay correctly once the connection returns, and whether the user was ever told what was happening.
Devices
Real devices or emulators — what does each actually catch?
Emulators are for breadth and speed; real hardware is for anything involving the physical device. Substituting one for the other is how release-blocking defects survive.
Emulators and simulators are genuinely useful: they cover many OS versions and screen sizes quickly and cheaply, they run in CI, and they catch the large share of defects that are really layout and logic problems. Treating them as sufficient is the mistake. They do not reproduce camera and sensor behaviour, real battery drain and thermal throttling, biometric authentication, push delivery under real conditions, or how the app performs on the mid-range device most of your users actually own.
The practical split is an emulator matrix for breadth in CI and a curated real-device set for the release gate, weighted to the handsets your analytics show. We will tell you which findings came from which, because a performance number from a simulator on a developer laptop is not a claim about a three-year-old phone.
