The short answer

Under the hood · How it works

Kotlin is Google’s official language for Android development. Jetpack Compose replaces XML layouts with a declarative UI model, Coroutines handle async work without callback hell, and the Jetpack library suite provides first-party solutions for navigation, local storage, dependency injection, and background tasks.

Bolder uses Kotlin when the project is Android-first or requires features only available on Android hardware — NFC payments, Google Pay, Android Keystore, WorkManager background tasks, or rugged device support for enterprise field apps. Native Kotlin means full Google Play compliance, Material 3 UI, and zero bridge overhead.
