In their own words
Autochords
Autochords is an iPhone and iPad app that helps songwriters find chord progressions and learn chords on guitar, piano and ukulele. Choose a progression style and key to see a main progression and alternatives for other song sections. Progressions can be previewed at a selected tempo with piano, guitar or ukulele playback, and the app provides diagrams for each instrument. Its built-in library contains dozens of progressions across styles of western music, though some require PRO. The free plan provides the app's free features. PRO adds more progressions, favorites, tempo changes, color themes, custom progressions and MIDI export. Export uses the iOS share sheet to open files in compatible apps, including desktop DAWs such as Logic or GarageBand. PRO costs $2.99 a month, $12.99 a year or 29.99 USD once for lifetime access. If a PRO subscription expires, existing favorites and custom progressions remain accessible, but users cannot add or remove favorites or create or delete custom progressions. Astrocode Pty Ltd develops the app, which is operated by a solo developer.
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.
