In depth
Kotlin apps for the world’s most diverse platform
Android means thousands of screen sizes, chipsets and OEM skins. We build with Kotlin and Jetpack Compose, test on a matrix of real budget and flagship devices, and keep APK sizes lean so installs do not stall on slower connections.
From Material Design 3 theming to background-work batteries and push notifications that actually arrive, we sweat the platform details that decide your Play Store rating.
What is included
- Kotlin + Jetpack Compose with clean architecture
- Device-matrix testing on real low-end and flagship hardware
- Play Console setup — listings, staged rollouts, vitals monitoring
- Size and battery budgets enforced in CI on every build
Frequently asked questions
Do you develop in Kotlin?
Yes. We build native Android apps in Kotlin with Jetpack Compose and modern architecture for clean, testable, future-proof code.
How do you handle the huge range of Android devices?
We test across screen sizes, densities and OS versions on real devices and emulators, and set performance budgets so the app runs well on mid-range phones, not only flagships.
Can you publish to Google Play and manage releases?
Yes. We handle the Play Console, staged rollouts, signing and store assets, and can release under your own developer account.
Do you follow Material Design?
We follow Material 3 guidelines so your app feels native to Android users, with proper theming, dark mode and accessibility built in.
Can you integrate Firebase, payments or maps?
Absolutely — Firebase, Google Pay, Maps, push notifications and analytics are common integrations we wire up and test as part of the build.
