Chet vs The Ear Gym

Chet is a free iOS and macOS app for ear training and music theory. A guided learning path supports self-paced study, alongside a library of musical games. 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].

The Ear Gym is an Android and iOS ear-training app covering intervals, chords, scales, rhythm, harmony, solfege, and perfect pitch. Exercises let users identify, compare, construct, read, sing, or play intervals using piano and guitar sounds. Guided Mode moves from beginner listening through intervals, chords, scales, rhythm, and harmony. Custom drills can specify intervals, chords, scales, keys, clefs, octaves, instruments, and tempo. Additional activities include sight reading, melodic dictation, harmonic analysis, chord progressions, and cadences. Session statistics, streaks, and badges track practice, and the app listing says it works offline. Free Start costs nothing and provides drills at the user's own pace. One-time purchases cost $2.99 as a one-time purchase for Guided Mode, $2.99, paid once for Free Mode, or $4.79, paid once for the Complete package. The App Store description says the full app uses a one-time purchase with no subscription or ads.
