Quick answers
No sound? Check the volume slider in the FX tab and the master volume of your device, and make sure the app is not muted. Tap anywhere in the app once — Android only starts audio after your first touch. Also check that the tracks you expect to hear are not muted (M) or that another track is not soloed (S).
The app is landscape only. That is intentional — the drum grid needs the width. Turn your phone sideways.
Where are my exported WAV files? The ⬇ button renders your beat to a WAV file and opens the Android share sheet. From there you can save it to Files, send it to yourself, or open it in another app. The file is written to the app's cache, so save it somewhere permanent if you want to keep it.
I lost my project. Projects are stored on the device only, with no cloud backup. Clearing app data or uninstalling removes them permanently. Export a WAV of anything important.
Does it need internet? No. Every sound is synthesized in code on your device and the app works fully offline.
Is it really free? Yes — no ads, no subscriptions, no in-app purchases.
