Apple's September 2026 health and fitness announcement describes new Apple Watch capabilities built on Apple Intelligence and a new health sensing system. They include Readiness, a daily read on the body's capacity, a redesigned Health app, Workout Buddy that works without a nearby iPhone, and improved treadmill accuracy from new machine learning models. Creators covering the launch also mention audio intelligence features: sound recognition, Live Rewind (showing the last 15 seconds of conversation as text) and Siri recaps. The provided Apple page does not detail the audio features, so these come from creator commentary.
watchOS 27 is available from 14 September 2026 for Apple Watch Series 9 or later, Apple Watch SE 3 and Apple Watch Ultra 2 or later. It requires an iPhone 11 or later, or iPhone SE 3, running iOS 27. The redesigned Health app requires an Apple Intelligence-enabled iPhone or iPad. Some features require AirPods Pro 3 or an iPhone connection, and Workout Buddy is available in English and Spanish.
Apple states that not all features are available on all devices or in all regions, and that availability may vary due to local laws and regulations. Server-side Apple Intelligence features are subject to daily usage limits. Apple says the Vitals app is for wellness purposes only, not medical use.
