I was expecting, and hoping, Apple would launch some kind of AI-powered health feature on the Apple Watch at WWDC 2025, but Workout Buddy wasn't exactly what I had in mind.
I'm the kind of person who spoils any and all surprises by reading the last page of a good mystery novel, or the finale synopsis of a Netflix whodunit before I've even gotten through the pilot. So I went into WWDC, Apple's annual developers conference, having read all the rumors, feeling pretty confident that I knew most of what was coming to WatchOS 26: a smarter Health app with AI coaching that could finally turn all my fitness metrics into meaningful, personalized guidance.
What we actually got during Apple's WWDC keynote was a bit different... and that's not necessarily a bad thing. Rather than unleashing a flood of generic coaching suggestions or unsolicited advice (like caffeine restriction windows, which should not exist in my vocabulary), Apple is being intentionally conservative with its approach to AI on the watch, testing the waters with Workout Buddy and laying the groundwork for more meaningful, context-aware insights.
Workout Buddy will take all your past fitness data into account, including training load, move rings and past workouts.

Workout Buddy isn't meant to be a coach (at least not in the traditional sense). It won't train you for a marathon or map out a four-week plan to boost your VO2 max. What it will do is act as a voice in your ear, offering encouragement during a workout based on your past fitness data. Think: "That was your fastest mile ever," or "You've just crossed 500 miles for the year."
For some people, that kind of affirmation might be enough to keep pushing forward. But I'm the kind of runner who thrives on structure and tough love. I should note that I haven't tested Workout Buddy, but from what Apple showed off, Workout Buddy won't cut it for me -- at least not yet. I already rely on pace and heart rate alerts to let me know when I'm slacking. What I really need is a drill-sergeant-style coach that handles the math for me, so I can focus on my stride, breathing and whatever podcast is carrying me through mile four.

What Workout Buddy is doing is technically impressive, combining exercise and health information and turning that into a conversational voice that gives you a personalized pep talk. It proves that Apple has both the data and the processing power to analyze workouts in real time and turn that data into something meaningful. It's the first step toward a more responsive, intelligent Apple Watch experience that doesn't just track your fitness, but actively helps you improve it.
It also offers a window into Apple's broader strategy for AI on the Watch. Whether due to hardware limitations (Workout Buddy relies on Apple Intelligence, which requires an iPhone 15 or newer model communicating with the watch) or just Apple being Apple (cautious, user-first and deliberate), the result is a feature that feels thoughtfully scoped rather than rushed and half baked. It's not shouting unsolicited advice or drowning users in confusing metrics. It's dipping a toe into coaching, not diving in headfirst.
Now that the groundwork is there, it feels like only a matter of time before we get a true AI-powered health coach.
Workout Buddy could pave the way for more real-time coaching on the wrist.

But maybe, if I had the right incentives or feedback, I'd get on board. The new Vitals app already does a decent job of flagging early signs of illness, but imagine a proactive sleep coach that tells me my room's too hot to hit deep sleep. That's the kind of data driven encouragement I'd actually listen to.
For now, Workout Buddy is limited to eight workout types: indoor and outdoor running and walking, outdoor cycling, HIIT, functional strength and traditional strength training. It'll arrive in September with the watchOS 26 update -- alongside a handful of other features you can read about here.
