ChordU vs Reverse Chord Finder Pro

ChordU identifies chords in audio and aligns them with musical notation. Users can also find a song on YouTube, copy its link and search for it in ChordU. A song may have simplified, advanced, bass or edited chord arrangements, as well as treble-clef and bass-clef note versions. Chord diagrams cover guitar, piano, ukulele and mandolin. On the website, users can obtain PDF chord and note sheets, MIDI files and synthesized notes in WAV format. MusicOnly mode provides controls for vocals, bass, drums and other instruments, and can export a mixed audio download. Local music uploads and MusicOnly for those uploads require Premium; Premium also permits chord downloads without a stated monthly limit. The Free plan has limited access, while Premium costs $5.00 per month. ChordU is available on Android, iOS and the web. Its terms limit song and chord use to personal, non-commercial purposes.

Reverse Chord Finder Pro identifies chord names from two or more selected notes. Notes can be entered through a piano, string-instrument layout or music-score notation. The app includes more than 100 chord types and can play results as block chords or arpeggios. Partial matching helps isolate passing melody notes, while Favorites stores identified chords. String layouts support three to twelve strings, left-handed setups and capo options. Music Score mode offers treble and bass staves in all 12 major and minor keys. Users can inspect intervals, chord structure and naming options. Supported instruments include piano, guitar, bass, ukulele and other three- to twelve-string instruments. It runs on iOS and macOS; listings require iOS 15.6 or later and macOS 13.0 or later on Apple M1 or later. Pricing includes a seven-day trial, with personal, family and lifetime plans.
