Can you test how our app performs on slow or unreliable networks?

Yes, we specifically test under simulated slow, intermittent, and offline conditions, which is especially relevant for apps serving users across LATAM markets. This catches failures that only show up outside ideal network conditions.

Will testing help us avoid app store rejection?

We review builds against current Apple App Store and Google Play guidelines before submission to catch common rejection triggers early. This is not a guarantee against rejection, but it substantially reduces avoidable delays.

Do you test both native and cross-platform apps like React Native or Flutter?

Yes, our approach adapts to native iOS/Android apps as well as cross-platform frameworks like React Native and Flutter. The testing goals remain the same regardless of how the app was built.

Quality Engineering

Mobile App Testing

Quantum Altus provides mobile QA across iOS and Android, combining device-lab testing, automation, and real-world network conditions to ship apps that hold up outside the emulator.

Discuss Mobile App Testing

Who It's For

Built For Teams Like Yours

Companies launching or maintaining a native or cross-platform mobile app

Product teams needing coverage across a wide range of devices and OS versions

Businesses with apps that must work reliably on inconsistent LATAM network conditions

Teams submitting to the App Store or Google Play who need pre-submission validation

Mobile products where crashes or performance issues directly hurt retention and ratings

The Problem

Business Problems We Solve

The app works in the emulator but crashes or misbehaves on real devices

Older devices and OS versions are not covered, alienating part of the user base

Poor performance on inconsistent mobile networks causes user drop-off

App store submissions get rejected due to issues that testing should have caught

Push notifications, permissions, and deep links are not thoroughly tested

What Quantum Altus Delivers

Detailed bug reports with device, OS, and reproduction context

Key Capabilities

Features & Capabilities

Real Device Testing

We test on actual physical devices in addition to emulators and simulators, catching hardware-specific issues that virtual environments miss. This includes older, lower-spec devices common among real users.

Cross-Platform Coverage

We test both iOS and Android builds with attention to each platform's specific UI conventions and behavior. A pass on one platform is never assumed to mean a pass on the other.

Network Condition Simulation

We test app behavior under slow, intermittent, and offline network conditions relevant to LATAM markets. This catches failures that only appear outside a fast office wifi connection.

Push & Permissions Testing

We validate push notifications, permission prompts, and deep linking behavior across both platforms. These are common sources of bugs that are easy to overlook until a user reports them.

App Store Readiness Review

We check builds against Apple App Store and Google Play submission guidelines before you submit, reducing the risk of rejection and delayed launches. This catches avoidable issues before they cost you a review cycle.

Automated Regression Coverage

We build automated mobile test suites for critical flows so every new release gets fast regression validation. This keeps manual testing focused on new features and edge cases.

FAQ

Mobile App Testing — FAQ

We use a combination of real physical devices and emulators/simulators, since real devices catch hardware and OS-specific issues that virtual environments often miss. The mix is scoped to match your actual user base.
