Apple releases third developer betas across multiple platforms with new health and system features.

Apple is skipping the 27.1 releases for most devices; iOS 27.1 is reportedly being tailored for the upcoming foldable iPhone Duo.
Earlier iOS 27.2 beta builds added FaceTime dual-capture support and brought Apple TV profiles from tvOS 26.2 to iPhone.
The second beta contained signs of an AutoLock anti-theft feature that could lock an iPhone if it is detected as stolen, although the feature was not accessible to testers and appeared nonfunctional.
The second watchOS 27.2 beta restored the app switcher, which had been removed in watchOS 27.0, using a different gesture.
Apple’s first public 27.0 releases included Liquid Glass intensity controls, per-category Screen Time limits and schedules, separate volume controls for alerts, and new photo-editing options.
Apple released third developer betas across all major platforms this week, continuing its rapid testing cycle for operating systems launching later this month or early next. OSXDaily reports the new builds cover iOS 27.2, iPadOS 27.2, macOS Golden Gate 27.2, watchOS 27.2, tvOS 27.2, and visionOS 27.2 — arriving roughly two weeks after the previous beta round. The software remains early-stage and Apple warns developers against installing it on essential devices.
The updates bring notable features to health and device management. iOS and watchOS now feature a redesigned Health app with Insights, Longevity, and readiness tracking capabilities. RedmondPie notes macOS gains expanded Siri language support plus redesigned brightness and volume controls. An anti-theft feature called AutoLock has appeared in testing builds, though it remains nonfunctional and inaccessible to testers.
Apple is entirely bypassing version 27.1 for most devices — an unusual move that signals iOS 27.1 is being reserved for specialized hardware. iClarified reports iOS 27.1 is tailored specifically for the upcoming foldable iPhone Duo. This suggests Apple wants that device to launch with custom software optimized for its unique form factor, rather than rolling out a standard version to all iPhones first.
The Health app overhaul brings three major new sections to iPhone and Apple Watch. The Insights view provides quick health summaries, while Longevity tracking focuses on lifestyle factors linked to longer living. A readiness feature measures daily wellness and recovery. These changes build on Apple's existing fitness and health monitoring capabilities, giving users more granular insight into long-term health trends beyond simple activity rings.
Earlier beta builds contained code for AutoLock, a theft-deterrent system that automatically locks a stolen iPhone when theft is detected. RedmondPie notes the feature appeared nonfunctional in testing builds and remains inaccessible to developers. The feature could become one of Apple's most aggressive anti-theft protections, automatically disabling a phone the moment it identifies suspicious ownership change. Full functionality details remain unclear as testing continues.
The second watchOS 27.2 beta brought back the app switcher, which Apple had removed entirely in watchOS 27.0. Rather than returning the old interface, Apple implemented the switcher using a new gesture, giving users faster access to recently used apps without swiping through the home screen. This reversal suggests user feedback pushed Apple to reconsider the elimination of this core navigation tool.
