Subscriptions

How do I cancel?

Open Settings on your iPhone, tap your name, then Subscriptions, then Ear Training, and tap Cancel Subscription. You keep access until the end of the period you paid for. To avoid being charged after a free trial, cancel at least 24 hours before the trial ends. You can also open this screen from Profile → Subscription in the app.

I paid but the app still shows the subscription screen

Tap Restore Purchases on the subscription screen or in Profile, and make sure you are signed in with the same Apple Account you bought with. If it still doesn’t work, email us.

How do I get a refund?

Payments go through Apple, so refunds are handled by Apple. Request one at reportaproblem.apple.com.

Can I use my subscription on another iPhone or iPad?

Yes. Install the app on the other device, sign in with the same Apple Account, and tap Restore Purchases.

Using the app

I can’t hear any sound

Check that the ringer switch (or Action button) is not set to silent mode, turn the volume up, and make sure no other app is using the audio. If you use Bluetooth headphones, try disconnecting and reconnecting them.

Rhythm taps feel late with AirPods or Bluetooth headphones

Bluetooth audio arrives a little late. Calibrate once from the rhythm screen so the delay doesn’t count against you, or use the iPhone speaker or wired headphones.

The vocal range finder isn’t hearing me

Make sure microphone access is on in Settings → Privacy & Security → Microphone → Ear Training, and try a quieter room. Sing each note on “ah” and hold it for about a second. Your voice is analyzed on your phone and never recorded.

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

Yes. You can pick your note naming in Profile.

I missed a day. Is my streak gone?

Not necessarily. You earn rest days as your streak grows, and the app uses one automatically to cover a missed day.

Will I lose my progress if I delete the app?

Yes. Your progress is stored only on your phone, so deleting the app deletes it. Your subscription is not affected: reinstall and tap Restore Purchases.
