Ella vs Note Precision: Intervals

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.
