ChoordinatorThe whole room on the same chart.
Broadcast your chord charts, everyone scrolls in unison, anyone can join with a code.

Pick a song on your phone. Every phone in the room updates instantly — no screenshots, no scrambling.

Paste anything. Drop a PDF or DOCX. We split it into individual songs.
How it works
Three steps. First one takes the longest. After that, it's two taps.
Import your charts
Paste a chord chart or drop a songbook PDF. We split it into individual songs.
Start a session
One tap generates a memorable code like tin-roof or the-horns.
Share the code
Bandmates type it on any phone. No install. No signup.
Keys detected automatically on every chart.
Tap any chord to see how to play it.
Setlists with estimated duration for gig planning.
Bands share a library, a setlist, and color-coded cues.
Custom reminders per song — shared, per-instrument, private — because no two players read the chart the same way. Owners curate the catalog; members rehearse. Invites go by code.
