Chord Analyser
Marseille, France
What it is
Chord Analyser identifies chords entered as notes on a piano keyboard or fretboard, then displays playable positions for a selected chord. Its library recognizes over 3,500 chords and provides a dictionary with positions computed algorithmically. The chart editor supports measures, subdivisions, repeats, time and key signatures, playback, automatic voicing, and PDF export. The Free plan is free, has no time limit or ads, and includes one chord chart. Additional charts require the full version, a one-time payment whose price depends on the app store. The full version adds eight instruments, open tunings, MIDI input, unlimited charts, and chart transposition. Microphone recognition is an Android-only beta that identifies one chord at a time and may struggle on older phones. The maker says real-time audio transcription is processed on-device and does not require internet access. The app is available on Android and iOS and is described as serving learners, composers, performers, and musicians who play across instruments.
