Apple's watchOS 27 introduces three Health-focused upgrades for Apple Watch users. The most notable addition brings perimenopause and menopause support to the Cycle Tracking feature, which can now notify users aged 40 and above when logged cycle patterns suggest perimenopause. The system includes symptom tracking and educational resources, though Apple emphasizes these notifications don't replace medical diagnosis.

Workout Buddy, the AI coach introduced in watchOS 26, receives three meaningful updates. It now delivers motivation based on personal fitness history with new data insights covering pace, distance, and workout duration progress. The feature works independently without an iPhone nearby, and adds Spanish language support for personalized coaching.

Quality-of-life improvements round out the release. Motion tracking algorithms have been refined for indoor walks and runs, promising more accurate distance measurements on treadmills. Additionally, step counts from the Health app and Fitness app now sync together — a gap that persisted until this update. These software changes arrive ahead of the expected Apple Watch Ultra 4 and Apple Watch Series 12 hardware launch this fall, suggesting Apple is polishing the health platform before its next flagship devices debut.
