Requirements

Your app must be available on both iOS and Android and built with Kotlin Multiplatform, Compose Multiplatform, or both.

What Judges Are Looking For

  • Cross-platform quality — required: A creative, polished app built for multiple platforms. Consistency and quality matter more than the number of platforms supported.
  • Community interaction — optional: Share the work in a way people enjoy, such as a useful blog post, devlog, article, video, or social update explaining how you built the app.
  • Giving back — optional: Help the Kotlin Multiplatform ecosystem by publishing a library, contributing to a library you use, open-sourcing a reusable part of the app, or improving documentation, samples, or tooling.

What To Include

  • Live links to the fully published app on both Apple's App Store and Google Play.
  • A description of how you used Kotlin Multiplatform or Compose Multiplatform.
  • Links to any public posts where you shared what you learned.
  • A description of your contribution to the ecosystem, with links to any library or pull request.
