WebConvoy designs and builds Android applications in Kotlin and Jetpack Compose, from the first wireframe through Play Console submission and post-launch support. Every build is tested against Google Play's current policy set, so it clears review without a rejected build eating into your timeline.
Teams come to us for products that need to feel native across real-world hardware: dozens of screen sizes, foldables, tablets, and devices still running two OS versions behind the newest release, not just the reference emulator.
No cross-platform shortcuts unless the brief calls for one — native code where it counts.
Signing keys, staged rollouts, policy checks, and appeals are ours to manage, not yours.
Adaptive layouts, camera and sensor integrations, and wearable companion apps, when the product needs them.
Android ships a major release every year, and older devices don't disappear — we keep your app working across both.
The same Kotlin foundation, adapted to the compliance, data, and workflow needs of your sector.
The same engagement every client goes through, logged the way we log an app's own release notes.
Product workshops, user flows, and a locked feature list, so the estimate you get is the one you pay.
High-fidelity screens in Figma, built against Google's Material Design 3 guidelines, with a clickable prototype for sign-off.
Kotlin and Jetpack Compose implementation in weekly sprints, with a staging build on a Play Console closed testing track for review as we go.
Manual and automated testing across a real device lab spanning screen sizes and OS versions, plus a pass against Google Play policy.
Google Play submission, staged rollout monitoring, and a support window for the fixes real users always surface.
A breakdown of the Android-specific skills used across a typical build, not a generic technology list.
Android runs on far more device shapes than any single OEM ships. We build and test for that spread instead of assuming a reference device.
Google Play requires every app to disclose what it collects and how it's protected. We build to that standard from the first sprint, not as a form filled out before submission.
All network calls run over TLS; nothing sensitive travels unencrypted between the app and your backend.
Analytics and crash reporting are scoped to what the product needs — never packaged for resale.
Account and data deletion flows ship with the app, not bolted on after a policy review flags it.
We request only the runtime permissions a feature actually uses, which is also what Play policy checks for.
Pick the model that matches how much control and continuity your project needs.
A locked spec, a fixed price, and a fixed delivery date. Best for a well-defined app with a clear feature list.
A Kotlin team embedded with yours, sprint by sprint. Best when the roadmap will keep evolving after launch.
One or more senior Android engineers who join your existing team and report into your own process.
Our app went from a rough idea to something that actually feels native on Android. The team caught interface details we hadn't even thought to ask about.
Communication stayed clear through every sprint, and the build we received matched the prototype almost pixel for pixel. Submission was handled without a single policy rejection from Google.
What stood out was the post-launch support. When Android shipped its next version, our app was already updated and tested before most of our users noticed anything had changed.
What clients usually ask before starting an Android build with us.
Most builds run 8 to 14 weeks from a locked scope to Play Store submission, depending on feature count and how much backend integration is involved.
Yes. Layouts are built with adaptive Jetpack Compose views so the same app scales correctly across phones, tablets, and foldables.
We do, end to end — signing keys, store listing assets, policy checks, and any appeals Google's review team requires.
Yes. We start with a codebase audit, flag anything blocking a Kotlin migration or a future Android release, and give you a clear plan before writing new code.
We set a minimum supported API level with you up front and test against it directly, rather than assuming everyone is on the newest OS.
