Audio

Check your device volume and mute setting, switch to another app and switch back to Interval Trainer, and then try Replay or Play again.

Microphone

Hum and Spectrum need microphone permission. Open the system Settings app, find Microtonal Interval Eartrainer, and enable Microphone. A quiet room and steady notes give the clearest pitch reading.

Game Center

Sign in under Settings → Game Center on your device. Training still works without Game Center; it is only needed to sync achievements and use friend challenges.

Privacy

Microphone audio is analyzed on your device and is not recorded or uploaded. Read the full privacy policy.
