Turn any song into something you can play along to: chords detected for you, four
stems split out, any phrase looped at half speed without changing pitch.
All of it runs on your iPhone. No audio is ever uploaded.
That's on your own. With a band, everyone shares one chart and one playhead.
■ Chord detection, stems and phrase looping
Import a song and get its chart in about ten seconds, right on the device; split it
into drums, bass, other and vocals whenever you need to, then loop one phrase as
long as you like: 0.5x-1.5x without changing pitch, solo or mute any stem.
Paste in the lyrics and the phone listens to the song and puts each line on its
bars (needs iOS 26).
■ Backing tracks for practising alone
Drums, bass and guitar follow your chart. Nine styles (pop, rock, ballad,
country, shuffle blues, reggae, funk, jazz swing, bossa nova), each with two
alternate arrangements, and each part can be muted.
The harmony comes from your chart: what you write is what you hear.
■ Video practice
Import a lesson video from your phone, mark in and out, loop those few seconds
full screen, slowed down if you like.
■ Number-system charts
No staves, no tabs, just the numbers (1 5 6 4).
Change the key and every chord on every screen follows.
■ The chart moves by itself, so your hands stay on the instrument
Hit play and the chart advances at the song's BPM: which beat you're on,
what this bar is, what comes next. Section changes come with a countdown.
■ Songs are written in sections
Intro, verse, chorus, bridge. Each section carries its own progression and
repeat count: you are in the chorus, it goes 1 5 4 6, pass 2 of 3.
Singers can switch to the lyrics view and get prompted line by line.
A full chart can also live on your Home Screen: pick a song in Settings and
add the widget.
■ On iPad, it's the music stand
The rehearsal view lays out the whole song like paper: one panel per section,
four bars to a row, lit up to wherever the band is. Put it on a stand and play.
■ Local network sync, no internet needed
One person hosts, everyone else types a four-digit room code. The leader starts,
changes tempo, jumps sections, locks a loop, and every playhead moves together.
No server, no account, no sign-in.
■ Rehearsal recording
Plug in your mixer or audio interface and record the whole session. Every time
someone hits play it becomes a take; keep the ones worth keeping and export m4a.
■ Full-song overview and PDF export
What you see is what you print: the same chart, the same page.
