Rechord
Play a chord. Hear its name.
Strum a guitar or play a piano and Rechord names the chord instantly — then shows it in the Chordology colour system, so you see the harmony, not just read it.

Questions
How does Rechord name a chord?
Play three or more notes together on a guitar or piano and let them ring. Rechord analyses the sound live and shows the chord name — majors, minors, sevenths, extensions and more.
Does Rechord record my audio or need the internet?
No. Audio is analysed live on your device and is never recorded or sent anywhere. The microphone only listens while you’re naming a chord, and Rechord works without a connection.
Is Rechord free?
Yes. Naming single chords is always free and the free version keeps your last 10. Rechord Pro is a one-time purchase that captures whole songs and keeps your full history — no subscription, ever.
Can Rechord capture a whole song?
Yes, with Rechord Pro. Record a full progression on a timeline as you play, name the key, and export a clean chord chart to keep or send to a bandmate.
