Coco vs Ella

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.

Ella is a free sight-singing app that trains the ear and voice through exercises, microphone feedback, and progress tracking. It listens through the device microphone, evaluates pitch, intonation, and intervals, and displays singing pitch in a detailed graph. An on-screen tuner and varied exercises support practice, while a guided learning path moves through musical concepts from beginner to advanced. Practice Mode lets users listen before singing; Play Mode tests skills and records personal-best scores. The App Store listing also describes global leaderboards and competition with friends. Ella runs on iPhone, iPad, and Mac, with iOS and macOS listed as platforms. Its privacy policy says exercise data and other in-app activity may be sent to the company’s cloud and saved on the device. Users may choose to share usernames, scores, or exercise data in some exercises. The app does not access contacts, phone numbers, or messages. It is not intended for children under 13, and absolute security cannot be guaranteed.
