Fretboard Pocket

Stop juggling music theory apps. Fretboard puts everything in your pocket.

Scales, chords, progressions, drum patterns, and ear training — all in one app, built for beginners, powerful enough for working musicians. No subscription. No ads. Works offline.

LEARN FASTER WITH INTERACTIVE VISUALS

See your scales and chords light up in real time on a full guitar fretboard, 4-string bass, or 88-key piano keyboard. Watch the Circle of Fifths rotate as you explore keys and modes. Tap any note — hear it instantly with realistic instrument sounds.

Music theory stops being abstract the moment you can see and hear it.
