Vocals, drums, bass, and instruments — separated entirely on your iPhone. On-device AI, no upload, no cloud queue. Works on a flight.
Download on the App StoreBuilt for the people moving cloud apps couldn’t serve — musicians, producers, and karaoke fans who don’t want their tracks on a stranger’s server.
Vocals, drums, bass, and instruments — separated in one tap. Apple Neural Engine does the work, on your iPhone.
Separation runs locally. Use it in studios with bad wifi, on a plane, in a basement — no internet needed.
Your tracks stay on your iPhone. No servers, no account, no analytics on your audio. Unreleased material stays unreleased.
Three steps. Four stems. Zero cloud.
Import from Files, Voice Memos, or AirDrop. Share from any app.
Apple Neural Engine extracts vocals, drums, bass, and other in seconds.
Mute or solo each stem. Loop a section. Save WAV or MP3, share to GarageBand.
