Kvizo
An Android quiz app built with Kotlin and Jetpack Compose — community quizzes, anime avatars and Ed25519 signed content.
What it is
Kvizo serves quizzes to a community. Quiz packs are downloaded into the app and verified with Ed25519 signatures, so players only ever load authentic content. The UI is native Android, built fully in Jetpack Compose.
Highlights
- Kotlin + Jetpack Compose UI
- Community quiz packs
- Ed25519 signed content verification
- Anime avatars
Why I built it
Quiz apps are everywhere, but none did community content with cryptographic verification the way I wanted. Kvizo mixes Kotlin-first Android development with a small Ed25519 trust model.
