What we’re expecting
Workout Buddy debuted with an iPhone requirement. watchOS 27 removes that limitation, and Series 12 is expected to be the first new Apple Watch to include the feature from day one.
Workout Buddy was one of the best new fitness features Apple introduced, but it originally relied on a compatible iPhone. With watchOS 27, the AI now runs on the watch itself, so you can leave your phone at home and still get coaching, pace updates, and encouragement during workouts. If you regularly run or cycle without your phone, this is one of the most meaningful watchOS 27 upgrades.
