Android App Development Company by Gamostar

Android powers most smartphones in the world, which makes it the fastest way to reach a large audience. Gamostar is an Android app development company that builds native apps in Kotlin and Java using modern Android architecture (MVVM, Jetpack Compose, Coroutines, Room and Hilt).

We build for the whole Android ecosystem: phones, tablets, foldables, Wear OS and Android TV. Every app is tested on real devices across screen sizes and Android versions, optimised for battery and start-up time, and prepared for a smooth Google Play launch.

From on-demand and fintech apps to real-time multiplayer games, our Android developers deliver clean, maintainable code and hand over the full source code.
