ChordTrainer

Learn open guitar chords, with your microphone listening in.

ChordTrainer is a native iOS app for learning the essential open chords — Em, Am, C, G, D, E, A, and Dm. Each chord comes with a clear finger diagram and a reference sound, and the app can listen through your device's microphone as you strum to tell you whether you nailed it.

Features

Diagrams for all 8 open chords, major and minor
Play-along reference sound for every chord
Listen & get feedback — strum into the mic and get instant accuracy feedback
No account, no ads, no third-party tracking

ChordTrainer only uses the microphone locally on your device to compare your strum against the selected chord. Audio is never recorded, stored, or sent anywhere.
