Auris vs Nootka

Auris is an ear-training app for students and musicians to practice listening skills through intervals, scales, melodic dictation, chords, inversions, and chord progressions. Its exercises are presented as suitable for beginners and advanced musicians, with no prior knowledge required. It runs on Android, iOS, and the web. Practice features include streaks, high scores, leaderboards, and detailed progress statistics. Free access is limited: an account saves progress, while the no-account option does not. Full access costs €4.99 per month on the yearly plan, billed yearly, or €9.99 per month on the monthly plan; both paid plans save progress and remove ads. A Schools plan lists full access, student targets, exams, and student information, and educator tools include tracking student progress and setting targets. Auris collects account, usage, and device information, and automatically adds new accounts to its mailing list with an opt-out option. It says data is primarily processed in the EEA, with some transfers elsewhere, including the United States. Practice time cannot be tracked in a private or incognito browser session.
