Chord Analyser vs chords·lol

Chord Analyser identifies chords entered as notes on a piano keyboard or fretboard, then shows playable positions for the selected chord. Its library recognizes over 3,500 chords, and its chart editor supports measures, subdivisions, repeats, time and key signatures, playback, auto voicing, and PDF export. The free version costs nothing, has no time limit or ads, and includes one chord chart. More charts require the full version, a one-time payment whose price comes from the app store. That version adds eight instruments, open tunings, MIDI input, unlimited charts, and chart transposition. Microphone recognition is an Android-only beta; it identifies one chord at a time and may struggle on older phones. The maker says audio transcription happens on-device without an internet connection. The app is available for Android and iOS and is described for learners, composers, performers, and musicians who play across instruments.
