ChordieApp

What ChordieApp is

ChordieApp helps musicians, teachers, and producers learn or teach chord names and read sheet music. It reads MIDI data and displays note names, manuscript notation, chord names, and the closest guitar fretboard. Notes can come from a MIDI controller or a QWERTY keyboard. The app does not generate sound, so hearing played notes requires a DAW or another external sound source. It includes reverse chord lookup and a voicing explorer for guitar, but no progression generator, chord chart export, mobile apps, or chord audio playback. Chord definitions are stored online and retrieved whenever the app runs, making a consistent internet connection necessary. The app responds only to MIDI channel 1. Windows users connecting a DAW need LoopMIDI. Mac licenses cost 25.00 USD once; Windows licenses also cost 25.00 USD once. Each license covers one computer, and switching between Mac and Windows requires another license.

Who it suits

It suits musicians, music teachers, and producers using Mac or Windows who want MIDI-based chord identification and notation.

Limits

There is no free plan. A license is limited to one computer, and switching between Windows and Mac requires a separate license; the app also responds only to MIDI channel 1.

Verdict

ChordieApp focuses on identifying chords and showing notation from MIDI input, with guitar-oriented voicing tools. Users need external audio software, internet access, and a separate license for each computer or operating system.
