Native Android Apps Built in Kotlin
High-performance Android apps in Kotlin and Jetpack Compose. From consumer apps to enterprise tools, Google Play approved and device-optimised.
What We Build for Android
Android's 3 billion active devices represent the largest mobile platform on earth, and the most fragmented. Building an Android app that works well across the full range of devices, screen sizes, OS versions, and manufacturer customisations requires genuine platform experience.
We build in Kotlin with Jetpack Compose for modern declarative UIs. Our Android apps are designed for the real Android ecosystem, tested across low-end and high-end devices, profiled with Android Profiler, and compliant with Google Play's current policy requirements.
Modern Kotlin with coroutines, Flow, and Jetpack Compose. Clean, testable, maintainable code.
We test across a device matrix covering budget, mid-range, and flagship Android. Real devices, not just emulators.
Every submission reviewed against current Play Store policies before upload. Target API level updates handled proactively.
Google Play Billing v5 for in-app purchases and subscriptions. Sandbox-to-production testing included.

Why Studios Choose Us for Android
Real Android expertise across the full device ecosystem.
We moved to Kotlin-first before it became the standard. Our codebases are idiomatic Kotlin, not Java with a Kotlin facade.
We test on real Android devices from budget to flagship, not just Pixel emulators. That's where fragmentation bugs hide.
Google's Play policies change regularly. We track target API level requirements and billing policy changes proactively.
60fps on a budget Android phone is hard. We profile with Android Profiler, optimise rendering, and set hard performance budgets.
