Make beats by stacking blocks — Strudel live coding without the typing.

A block-based front end for Strudel, the browser live-coding music tool. Instead of typing pattern code you stack blocks: pick a sound or tap notes on a piano, add effects, drag to reorder, and hear it change as you go. Blocks light up in time with the music. Sound browser with drum machines and instruments, chords, undo/redo, a pattern library, and share to strudel.cc so you can keep editing on the desktop REPL. Kotlin + Jetpack Compose, with the Strudel engine running in a WebView. AGPL-3.0.

⬇ Android (APK)Android 8.0 or newer. Your phone will ask to allow installs from your browser — that's normal for apps outside the Play Store. Sounds are streamed the first time you use them, so the first play needs internet.Updated 14 Sept 2026 23:02 UTC · 12.5 MB → Source codeAGPL-3.0. Build it yourself with Android Studio.Available

Early build (0.2.0). Audio only plays while the app is on screen — background playback is planned. Feedback goes straight to me from the ⋮ menu in the app; bug reports can attach the pattern you were editing. No account, no analytics.
