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.

What Is Workout Buddy?
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 means for the future
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.
