Intervals

Terms of use

Updated 20 September 2026

The app

Intervals is an ear-training app for iPhone. By using it you agree to these terms.

Apple licenses the app to you through the App Store. You may use it for personal practice. You may not copy, resell, or reverse-engineer it.

If you buy anything in the app, the purchase is handled by Apple. Refunds and billing follow Apple’s rules.

Singing exercises need the microphone. You can skip those exercises or deny access in iOS Settings.

The app is a practice tool. It does not promise a grade, a job, or perfect pitch. We provide it as-is.

How the app stores data is explained on the Privacy page.
