The watchOS 11.1 update brings a fix for an unreported bug that could affect sleep apnea detection on compatible Apple Watch models.

Here's how to track any breathing disturbances while sleeping using your Apple Watch and get notified if they point to possible sleep apnea.

The new Apple Watch feature that detects sleep apnea has been enabled for beta testers in the latest watchOS 11.1 beta 6 release.

Apple has removed the supporting iPhone apps for the Beddit sleep monitor accessory that it acquired back in 2017, but no longer sells.

Even though watchOS 11 works on Apple Watch Series 6 and newer, sleep apnea detection doesn't work on the first Apple Watch Ultra model.

Learn how to set your iPhone to automatically turn on the Reduce White Point feature when in bed, which will lower the screen brightness and reduce eye strain.
