SUS4 Capo Calc
Pick a key, get the capo position and shape. Done.
SUS4 Capo Calc solves a specific problem: you want a song to sound in one key but play it with chord shapes you know. Pick the key you want to hear, and the app lists every capo position up to the seventh fret with the shape to play there, easiest shapes first, each with a chord diagram.
Available on iPhone, iPad, Mac and Apple Watch, the Watch version is useful on stage. Check a capo position between songs, work out what key a capo and shape actually sound in, or shift a song up or down to suit a singer, without pulling out your phone.
On iPhone, iPad and Mac the calculation follows your tuning, with 25 to choose from across standard, dropped, open and modal tunings, and Find Key works out the likely key from chords you type in, with capo options for each. Capo maths is simple arithmetic, but doing it in your head mid-session breaks focus. SUS4 Capo Calc takes it off your mental load.
