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.
Reverse Chord Finder Pro
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.
