Rechord

Rechord hears a chord and names it — instantly.

Strum a guitar or play a piano and Rechord tells you exactly what you're playing, then shows it in the Chordology colour system so you can see the harmony, not just read it. Play three or more notes together and let them ring — that's all it takes.

NAME ANY CHORD BY EAR Point your phone at the instrument, play, and the name appears: majors, minors, sevenths, extensions and more. Everything you name is saved to your history, most recent first.

SEE IT IN COLOUR Every chord is drawn in Chordology's signature colour system, so patterns and relationships jump out. Tap "Open in Chordology" to see the same chord on guitar, ukulele and more.

CAPTURE WHOLE SONGS Record a full progression on a timeline as you play it, name the key, and export a clean chord chart. Perfect for figuring out a song, sketching an idea, or sending the changes to a bandmate. (Sessions are part of Rechord Pro.)

KEEP EVERY CHORD Naming single chords is always free, and the free version keeps your last 10. Go Pro to capture whole songs and keep your full history for good.

PRIVATE BY DESIGN Audio is analysed live, on-device, and never recorded or sent anywhere. The mic only listens while you're naming a chord.

ONE-TIME PURCHASE Rechord Pro is a single purchase — no subscription, ever.
