What language are Android apps developed in?
Kotlin — Google’s official, modern language, with Jetpack Compose or XML for the interface. We also maintain Java projects, but new products are built in Kotlin.
What is the cost of Android app development?
An MVP for Google Play starts at $1,000-5,000. A full native product with backend is $7,000-20,000+. Our calculator gives an exact range in 2 minutes.
Native Android or cross-platform?
If you only need Android, native is the right call — no premium for one platform. If you need both, Flutter saves ~30%. Native is worth it for hardware integrations, heavy background work and games. We’ll advise honestly at discovery.
Do you provide custom Android app development services?
Yes — every project is custom Android development with clean architecture, your own design and full GitHub access. No templated builds.
Do you help pass Google Play moderation?
Yes. We know the typical policy-rejection reasons, prepare the app for submission and support the process. If it’s rejected because of our mistake, we fix it for free.
A word from our mobile team
“Android is freedom and a challenge at once: thousands of devices where everything has to work equally well. WiFi Heatmap with 3M+ downloads taught us to build for real hardware diversity, not «for our own phone». Native Android is worth the money where audience coverage and hardware integration matter.
