Apple has released the third developer betas of watchOS 27.2, tvOS 27.2 and visionOS 27.2. The releases arrive alongside the third betas of iOS 27.2, iPadOS 27.2 and macOS Golden Gate 27.2, giving developers another round of software to test across Apple’s device lineup.

The new builds arrive two weeks after Apple distributed the second betas. Registered developers can install them through the Settings app on the relevant device. Apple has not detailed a specific feature list for all three updates, so the main changes may remain unclear until testing progresses.

watchOS 27.2 continues Health app testing

The most clearly identified change affects watchOS 27.2. Together with iOS 27.2, the update is being used to test Apple’s redesigned Health app, which the company introduced during its September iPhone event.

The updated app adds two new sections: Insights and Longevity. It also includes a readiness score designed to use health and activity information from Apple’s new Watch hardware, including the Apple Watch Series 12 and Apple Watch Ultra 4.

Because the Health app changes are being tested across both the iPhone and Apple Watch, users may need compatible software on both devices to experience the complete feature set. The source material does not specify whether the third watchOS beta adds new Health features beyond the broader testing already underway.

tvOS 27.2 and visionOS 27.2 details remain limited

Apple has not said what new features or changes are included in the third tvOS 27.2 and visionOS 27.2 betas. As with other pre-release software, the builds are intended for registered developers rather than general users, and their contents may change before public releases arrive.

The tvOS beta is being tested as Apple is expected to introduce a new version of the Apple TV 4K before the end of the year. That future model is expected to include Siri AI support, although Apple has not provided confirmed details about the product or its release timing in the available information.

How developers can install the betas

Registered developers can look for the updates in the Settings app on compatible Apple devices. Installing beta software can expose users to unfinished features or unexpected issues, making the releases more appropriate for development and testing environments than everyday devices.

Apple’s latest beta cycle covers its major operating systems, but the company has not announced final release dates for watchOS 27.2, tvOS 27.2 or visionOS 27.2. Additional features and fixes may appear in later builds before the updates become available more broadly.
