Chord Analyser vs ChordSequence

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.

ChordSequence is a free set of browser-based music tools for composing and exploring chord progressions. Its player performs chords selected by the user with drums, bass, piano, guitar, and synth, drawing on 548 rhythms that include pop, rock, salsa, and reggae. You can reorder chords, arrange them into sections, loop those sections, and edit individual instrument parts. The mixer offers volume, pan, mute, solo, EQ, and compression controls for each instrument, plus reverb for the overall mix. Songs can be exported as WAV audio or MIDI notes for use in a DAW. Other tools include a chord finder, transposer, key detector, Circle of Fifths, tuner, metronome, guitar and bass tabs, and a drum machine. The browser player is stated to work in Chrome, Firefox, Safari, and Edge. An Android app works offline, needs no account, and supports Android 8.0 or later; iPhone users can use the browser player. The Free plan is free, with all features, no usage limit, and WAV and MIDI export.
