A real band in your pocket.

It plays your songs, writes its own, and never needs the internet.

Free to try, nothing to install, no account. The apps for iPhone, iPad and Mac are on their way.

Your songsPhotograph a chord sheet, paste the chords or open a chart. The band plays it in the style, key and tempo you choose, with solos and a proper ending.
Its own songsA radio that composes as it goes: lofi, jazz, funk, rock and more. Every tape is new, and every tape has a code that brings the same song back.
On stageSet lists, a chart you can read from across the room, and a foot pedal for the fill, the extra chorus and the ending.

What we promise

It works in airplane mode. The apps compose and play on your device.
It collects nothing. No account, no ads, no analytics, no tracking.
Every sound is a licensed recording of a real instrument. The songs are written by rules, and nothing was trained on anyone's music.
