Summary
Chordio is an interactive 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 Chordio identifies played chords, naming them on the grand staff in real time. Harmony Explorer finds matching scales and suggests diatonic chords, borrowed chords, secondary dominants and tritone substitutions. Users can drag progressions into Logic Pro, Ableton Live, FL Studio and other DAWs as MIDI, or import MIDI chords for re-harmonization. Sheet Music includes tempo adjustment, looping, separate-hand practice, transposition and PDF printing. Lesson Packs let users play along with pieces in any key and at any tempo. The free download includes every workspace, built-in sounds, an on-screen keyboard and real-time MIDI chord detection. Full Unlock is a $14.99 one-time purchase for Mac, iPad and Vision Pro, with lifetime updates and no subscription; the iPhone version is purchased separately. The developer states that the app collects no data.
