In their own words
Chordio
Chordio is a music composition and theory app for iOS and macOS, with workspaces for composition, scales, modes, sheet music, music theory and lessons. Its library includes more than 40 scales. Connect a USB, MIDI or Bluetooth MIDI keyboard and it identifies chords in real time, naming them on the grand staff. Harmony Explorer finds matching scales and suggests diatonic and borrowed chords, secondary dominants and tritone substitutions. Progressions can be dragged into Logic Pro, Ableton Live, FL Studio and other DAWs as MIDI; MIDI chords can also be imported for re-harmonization. Sheet Music includes tempo adjustment, looping, separate-hand practice, transposition and PDF printing. Lesson Packs let users play pieces in any key and at any tempo. The free download includes built-in sounds, an on-screen keyboard and every workspace. Full Unlock costs $14.99 as a one-time purchase and includes Mac, iPad and Vision Pro, plus lifetime updates. The iPhone version is purchased separately, and there is no Android app.
ChordU
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.
