Scales, chords, tunings, a fast tuner, and an interactive circle of fifths — all connected, all beautiful. Built native for iPhone, iPad and Mac.
Rosewood and maple finishes, smooth orientation flips, and note placement that animates like a real instrument.
Majors, minors, pentatonics, blues and the seven modes — with correct spelling for every key, on guitar and bass.
Tap any note to hear it. Tap a chord to strum it. Tap play on a progression and hear it in your key.
An all-new dial built for tuning between songs, not staring at a screen.
Tap any key to see its signature, its relative minor, and the chords that live inside it. Your fretboard, chords and tuner all follow.
Open shapes, barre shapes, multiple voicings — or see the same chord spread across the entire neck.





Most apps do one thing. Fretkit's pieces talk to each other — pick a key once and everything follows.
