About this app

🎸 JamBuddy - Listen. Learn. Play.

JamBuddy turns your phone into a music practice workstation: hear chords in real time, see how they fit in the key, slow down hard passages, control ABC sheet music, transpose tunes, browse chord shapes, tune up, keep time, and capture ideas as notation.
