Blueprint 4-Track

Great for demos, first takes, and fresh ideas: voice and guitar at the kitchen table, or a band passing one phone around the room.

The sound of the machine is built in. Each track has its own set of knobs and there is no undo.

- Records one track at a time, from the built-in mic, a headset mic, or a USB audio interface.
- Sends any track through a space echo with spring reverb.
- Bends pitch and tempo together with a varispeed knob in the master panel.
- Has track merging/clearing, punch-in recording, and a metronome.
- Your recordings are WAV files saved on your phone. Share the song, or export the whole session.
- Works entirely offline and collects nothing.
- Pay once. No subscription, no ads, no account.
- Works on iPhone and iPad.

TIPS

- Overdub with wired headphones, so the mic doesn't pick up the other tracks.
- Don't use Bluetooth headphones while recording: they add delay, and only play in mono.
- Tap record while playing to punch in over a part you want to redo.
- Tap the ? at the top left for a guide to the controls.
