On November 20, 2024, Apple released the third beta version of watchOS 11.2, following the second beta just a week prior.

Alongside watchOS 11.2 beta 3, Apple also launched the third testing versions of tvOS 18.2 and visionOS 2.2, with anticipation for updates if new features emerge.

A standout feature in this update is the sleep apnea detection capability, which utilizes the Apple Watch's accelerometer to monitor wrist movements linked to breathing interruptions.

Users can track their sleep quality through the Health app, where they can review Breathing Disturbances data over one-month, six-month, or one-year periods.

This sleep apnea feature is particularly significant as sleep apnea affects around 1 billion people globally, potentially leading to severe health complications if left untreated.

Currently, the sleep apnea detection feature is limited in availability, but it may expand with future updates, such as watchOS 11.2 beta 3.

In addition to sleep apnea detection, watchOS 11.1 introduced two Apple Intelligence features for iPhone 15 Pro users: a Focus Mode that prioritizes urgent notifications and a summarization feature for notifications.

The specifics of the new beta version's features remain somewhat unclear, as all major functionalities of watchOS 11 were initially unveiled at WWDC 2024 and have been included in earlier updates.
