The future of Apple Watch AI is not a chatbot, but a coach. This year's Apple Worldwide Developers Conference (WWDC) is expected to bring a fresh batch of software updates, with all eyes on Siri's overhaul. While the WatchOS 27 update may get buried, it's not necessarily a bad thing if Apple is building a smarter coach rather than just a smarter assistant. Last year, WatchOS saw a big rebrand and the introduction of Apple Intelligence-powered Workout Buddy, which delivers personalized encouragement during workouts. However, the real potential lies in transforming Workout Buddy into a genuine coaching system that uses biometric data in real-time, providing in-the-moment feedback through AirPods. This would be a completely different category of health coach, requiring the level of in-the-moment peak heart rate accuracy the Apple Watch is known for. The rumored heart rate tracking improvements in WatchOS 27 would fit neatly into this vision. However, the Apple Watch still struggles with overnight data collection, which is crucial for accurate coaching. The solution may lie in a screenless Apple Watch companion, but it's not coming anytime soon. The question for WatchOS 27 is whether Apple can build an AI health coach that people will actually listen to, because it's in the right place, it collects the right data, and ultimately helps you change your habits.
