Apple has begun developer beta testing of Live Rewind and Siri Recap with iOS 27.3, with a public beta to follow; both are opt-in features for the Apple Watch Series 12 and Ultra 4. Live Rewind lets users double press the Digital Crown to bring up the last 15 seconds of a conversation as text, with the snippet disappearing automatically unless saved to the Siri app, and the double press also triggers a chime even in silent mode plus an animation on the Watch. Siri Recap turns a conversation into a title and a short list of key points, lets users choose when and where it runs, deletes unsaved recaps within seven days, and Apple says it does not identify speakers or retain raw audio. Fitness+ Gym Strength builds a four-week programme around the user's goals, experience, schedule and available equipment, then adjusts it based on how training goes, with the iPhone or iPad holding the plan and exercise videos while the Watch shows the next exercise, suggested reps and weight, and lets users log what they managed. The redesigned Health app, back in beta, includes Health Age.
