What's changed, in reverse chronological order. Have an idea for the next entry? hello@playfretboard.com.
A much smarter chord engine
- The chord dictionary grew from 17 types to 40 — 9ths, 11ths, 13ths, 6/9, add9/add11, half-diminished, altered dominants (7♭9, 7♯9, 7♯11, 7♭5, 7♯5), minor-major 7ths and 9ths, and more. Shapes that used to come back blank now have names.
- No more "Unrecognized". Every voicing with two or more distinct notes now gets a name, and anything that isn't a textbook match is labelled with the tones it adds or leaves out — "Cmaj7 · add ♯11", "Am7 · no 3rd".
- Ambiguous shapes now show their alternate readings. The same four notes can be Am7 or C6/A; tap a chip to switch and every interval label on the neck re-roots to match.
- Inversions and slash chords are named properly. A C major with E in the bass now reads C/E (1st inversion) instead of quietly calling itself C.
- Sharp/flat spelling. Chords pick the accidental a musician would actually write — D♭ not C♯, E♭m not D♯m — with a manual override in settings if you want everything one way.
- Left-handed mode: mirrors the neck, the capo, and the fret numbers, and keeps every label upright.
Alternate voicings, scale overlay, mobile polish
- Alternate voicings: when a chord is identified, the app now suggests up to three other common shapes you can click to load.
- Scale overlay mode: pick a root + scale (major, minor, pentatonic, blues, dorian, mixolydian, harmonic minor) and the fretboard maps every scale tone with interval shading.
- Mobile polish pass — bigger tap targets, no iOS zoom on selects, tightened settings panel layout, smoother capo dragging on touch.
