Guitar Visualizer

Mobile guitar chords and scales with a fretboard you can actually read under your fingers.

I play guitar badly and learn better when I can see the fretboard.

Chords, scales, and voicings mapped onto a phone-sized neck – CAGED shapes, jazz voicings, muted strings included. Built for practice, for the same reason a good instrument can briefly convince you that you sound like someone else.

Where it got hard

01
Turning music theory into geometry: movable voicings, relative frets, muted strings, and multiple tunings in one React neck component that still fits a phone.

Role

Solo – design, code, and shipping.
