What’s new
Version 1.1 · Updated October 17, 2026
Chordwerk now runs natively on iPad – portrait and landscape, with large chord diagrams for practicing on a music stand. Power chords: the power chord for the current chord is marked on the fretboard, and you can already see where the next one sits. More scales: besides the pentatonic, you now get blues, major, minor, all the modes, plus harmonic and melodic minor. Blue note: the pentatonic can show the blue note, switchable in Settings or right on the fretboard. Larger fret numbers and clearer fret markers, especially in the enlarged view.
