Cross-platform development is usually a trade-off. You gain speed, but you lose performance. With Kotlin Multiplatform (KMP), we found a way to eat our cake and have it too.

The Business Logic Layer

VxMusic shares 80% of its code between Android and Desktop (and soon iOS). This shared code handles networking, caching, database access, and audio processing. We write it once in Kotlin, and it compiles to native JVM bytecode or LLVM binaries.

Native UI Matters

Unlike Flutter, which draws its own pixels, KMP allows us to use Jetpack Compose on Android and SwiftUI on iOS. This means VxMusic always looks and feels like a native app. The scroll physics, the animations, the accessibility services—they all work out of the box.

The Future is Shared

We believe KMP is the future of mobile engineering. It allows our small team to compete with giants like Spotify by drastically reducing maintenance overhead without sacrificing the user experience.
