Lumen is a native Android wallpaper app built with Kotlin and Jetpack Compose. It pulls from multiple curated sources, applies dynamic theming, and handles set/preview/download with a clean Compose UI and proper lifecycle-aware loading.

Compose-first UI
The whole surface is Jetpack Compose — declarative previews, easy theming, and far less boilerplate than the View system.
Lifecycle-aware image loading
Loads are scoped to the visible screen and cancelled off-screen, keeping memory flat on long scrolls.
// OUTCOME
A polished, responsive wallpaper experience shipped to Android.
