Audio seems unchanged

Remove headphones, use a moderate volume, check the speaker opening, and test again. Stop if the device overheats or the sound is uncomfortable. Persistent problems may need repair.

Microphone test is unavailable

Check iOS Settings for Crisp microphone permission. The eject and tone tools do not require it.

Reminder did not arrive

Check notification permission and the reminder setting in the app.

Remove a hearing result

Open Hearing History and use the trash control next to the result you want to remove. Results are approximate and are not a medical diagnosis.
