Guitar Capo & Key Helper

Guitar Capo & Key Helper works out capo positions, transposed chords, and song keys - for beginners learning their first open chords and worship or campfire players following a leader in a different key. CAPO - Have a capo on and a shape in mind? Pick the shape and the fret and see the key it sounds in - Know the song's key? Pick it and see every capo position that lets you play it with an easy open shape, with the lowest fret highlighted TRANSPOSE - Type a chord progression and shift it up or down by semitones - Correct sharp/flat spelling in the result, not just note-number math - A "with capo N play" row suggests an easier open-shape fingering for the transposed chords - Unrecognized tokens (song sections, repeat marks) pass through unchanged KEY FINDER - Tap the chords you hear in a song - Ranks the most likely keys by how well the chords fit, with the matching roman numerals shown SHAPES - Reference diagrams for the standard open chord shapes: C, A, G, E, and D majors, plus Am, Em, and Dm - Watch a short video ad to unlock the open 7th-chord shapes for 24 hours This app is fully offline and works with no signal - useful in a basement rehearsal room or a campground with no bars.
