Support

Stuck, found a bug, or have an idea for the app? Email and you will get a reply from the developer.

For bugs, include your iPhone or iPad model, iOS version, the mode and level you were on, and what happened. A screenshot helps.

No sound?

The app plays through the media volume, so the ring/silent switch does not mute it. Turn the volume up with the side buttons while the app is open, and check that no headphones or Bluetooth speaker are connected and playing elsewhere.

Taps register late with Bluetooth headphones

Bluetooth adds a delay between the click you hear and the moment the app registers your tap, so every hit lands late. Open Settings › Calibrate tap timing and follow the prompts; the app then offsets your taps to match. If scoring still feels tight, choose the Relaxed timing window in Settings.

Can I use Do Re Mi instead of C D E?

Yes. Open Settings › Note names and pick the naming you use.

Where is my progress saved?

On your iPhone or iPad only. Levels, stats, streak and settings are stored in the app's local storage and are never sent to a server or synced between devices. There is no account.

How do I reset my progress?

Delete the app and install it again from the App Store. That removes all progress and settings. There is no in-app reset yet.

Which iOS do I need?

iOS 17 or later, on iPhone or iPad.

Does the app collect any data?

No. No analytics, no tracking, no ads, no third-party SDKs. Details are in the privacy policy.

What about the web demo?

The web demo is an older browser version of the rhythm exercises. It saves progress in your browser's local storage for this site; clearing site data for rubenreut.github.io removes it. On a computer you can tap with the Space bar. The App Store app is the current, complete version.
