Apple has released the first developer beta of iOS 27.3, introducing a redesigned Health app and several other changes. The company has also made the first developer betas of iPadOS 27.3, macOS 27.3, watchOS 27.3, tvOS 27.3 and visionOS 27.3 available to testers.
Among the features in iOS 27.3 beta 1 are Audio Intelligence additions, including Siri Recap and Live Rewind on Apple Watch. The update also brings Apple Intelligence features to China, although the beta does not include Siri AI.
The release adds Reachability for the iPhone Duo, vertical tabs in Safari and an adaptive Dark Mode. StandBy mode also gains functionality similar to that of the iPhone Duo across supported iPhone models.
Separately, Apple announced a Siri AI Developer Preview, now available to all developers to help them integrate their apps with Siri AI.
