Why
Choose Us?
Android's fragmentation is a feature, not a bug — if you build for it properly. We do.
Fragmentation handled, not ignored
We test across the real device distribution your users have — not just the Pixel in the office. Adaptive layouts, density buckets, and OS version coverage are part of every build, not a QA afterthought.
Play Store submission, end to end
We handle build signing, release tracks, store listing copy, screenshot assets, content ratings, and staged rollout. You don't touch the Play Console unless you want to.
Material You, done right
Dynamic colour, adaptive components, and predictive back gesture — we implement Android's design system fully, so your app feels native to every user's device, not just the designer's mockup.
Expected
Outcomes
01
Play Store approval without the back-and-forth
We build to Google's policy requirements from the first sprint — data safety declarations, permission rationale, target API compliance — so your submission doesn't bounce on a technicality after months of build time.
02
Performance that holds on the devices most of your users have
Not the flagship. The two-year-old mid-range phone your median user is holding. We profile, optimise, and test on real hardware — not just emulators — so the experience is fast for everyone, not just reviewers.
03
A codebase the next engineer can actually read
Clean architecture (MVVM + Clean), documented modules, and dependency injection set up correctly — so your next feature sprint doesn't require a full archaeological dig through the original code.
04
Crash rates and ANRs you're not embarrassed to show investors
Firebase Crashlytics, StrictMode in development, and automated UI tests in CI from day one — so your Play Store quality rating stays in the top tier and your reviews don't mention crashes.
But, Why App Stop?
We Build What Your Audience Needs
App Stop takes ownership of both product thinking and execution. We combine design clarity, engineering discipline, and market context to ship experiences that are fast, usable, and ready to scale.

FAQ
Frequently Asked Questions
Do you build Android apps with Kotlin or Java?+
Kotlin is our default — it's Google's preferred language and produces safer, more concise code with full coroutine support for async work. If you're on an existing Java codebase, we can work within it or migrate module by module without stopping feature delivery. We don't recommend rewrites for the sake of it.
Can you build for tablets and foldables too?+
Yes — and we treat it as a first-class requirement, not an afterthought. Adaptive layouts using WindowSizeClass, window insets, and multi-pane navigation are part of every build. Foldables get proper hinge-aware layout handling. Android TV support is available if your use case needs the living room.
Do you handle Play Store submission?+
End to end. We manage build signing, release track setup (internal → closed → open testing → production), store listing copy, screenshot and feature graphic assets, data safety form completion, content ratings, and staged rollout percentage. You get a launch-ready app and a documented release process you can run yourself going forward.
How do you handle Android's OS fragmentation?+
We set a minimum SDK level based on your target audience's real device distribution — not just the latest Android version. We use compatibility libraries to backport modern features, test on a representative device matrix covering the top manufacturers and OS versions your users have, and flag any feature-versus-compatibility tradeoffs early so you can make an informed call before build starts.
