Coco vs The Ear Gym

Coco is an ear-training app for musicians, offering short listening exercises to develop recognition of notes, intervals, chords, scales, and pitch. Its seven games are Sonar, Triad, Climb, Fall, Ladder, Span, and Sound. Rules generate game levels that can introduce more answer options, chromatic notes, wider octave ranges, faster play, and greater difficulty as players advance.

The Daily Workout selects a personalized set of usually one to three games based on practice history and areas to improve. The Daily Challenge instead gives every player the same questions and time limits for the day, with one attempt. Coco is available on Android, iOS, and in a web browser. An account is needed to save progress and sync statistics across devices. Most listening runs locally after content loads, but an internet connection is needed to submit results, update the proficiency index, and retrieve daily content. Coco requires sound and does not currently support a hearing-impaired mode; headphones are recommended for chord and harmonic-interval games. The free plan has daily session limits. Coco Pro offers unlimited daily practice and full progression, with pricing shown in the app at purchase.

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.
