JamBuddy - Tools for Musicians

Sheet music search and display, chord recognition, and live transcription with split screen so you can read and listen at the same time! JamBuddy names the chord you're playing in real time — root, quality, bass note, and where it sits in the key. It reads the sound, not a fixed fretboard, so real-time chord detection works with any instrument: guitar, mandolin, ukulele, fiddle, banjo, bass, piano, whatever you play. It's a chord identifier, key finder, and ear-training aid in one. Around that live read is a full practice kit tuned for jams: chord and key detection, a chromatic tuner, an accurate metronome, a searchable tune library, ABC sheet music with tabs, a song slow-downer, and live transcription. No ads, no subscription, core features all work offline.
