Exercises cover intervals, scales, arpeggios, chords, progressions, tonal sequences, famous tunes, and atonal sequences. Responses can use piano, guitar, bass, or multiple choice, and MIDI compatibility allows a MIDI keyboard. Practice Mode uses spaced repetition. Users can sign in to track progress and compete with musicians worldwide. The plan is listed as free, with no paid price or usage limit stated. Chet’s privacy policy says the app collects in-app activity such as exercise data and may transmit it to cloud storage. It is not intended for children under 13, and absolute data security cannot be guaranteed. Privacy questions and deletion requests go to [email protected].
