KotlinConf App is a multiplatform mobile and web application that demonstrates Kotlin Multiplatform development across Android, iOS, desktop, and web platforms.
The application serves as the official companion app for the KotlinConf conference. It uses Kotlin Multiplatform to share code across all client platforms, with Compose Multiplatform providing a unified UI layer. The backend runs on Ktor with Exposed for database access, allowing the entire application stack to be written in Kotlin while targeting diverse deployment environments.
This project is most valuable as a reference implementation for developers building multiplatform applications with Kotlin. It shows practical patterns for sharing business logic and UI code across Android, iOS, web, and desktop targets simultaneously. The application is published on Google Play, the App Store, and as a web deployment, making it a real-world example rather than a toy project. Developers evaluating Kotlin Multiplatform adoption can examine how a production application structures its codebase, handles platform-specific concerns, and maintains a single source of truth for shared functionality.
The project maintains active development with regular updates to support current Kotlin and Compose Multiplatform versions. The codebase receives ongoing refinements to build configurations and platform-specific implementations. The project demonstrates sustained investment in keeping the multiplatform toolchain integration current and functional across all supported targets.
