What is DroPilot?
DroPilot is a guitar harmony app focused on practical voicings. Instead of showing isolated chord diagrams, it lets you work with real chord progressions and compare different ways of playing each chord across the fretboard.
It is not just a chord dictionary. DroPilot is designed to help you understand how the same progression can sound completely different depending on the voicing, inversion, string set or drop chords you choose.
Free guitar tuner app — built in
Tune string by string with a clear meter and standard E A D G B E reference — a practical alternative if you usually look for a free online guitar tuner. Same app as your chord, triad and voicing tools: tune, then explore harmony on the fretboard.
