Apple Watch AI
Apple Watch AI: what can AI do with your watch data?
Apple's own AI on the watch is Workout Buddy, a spoken coach during workouts. You can also give your Apple Watch data to an AI you already use, such as ChatGPT, Claude or Grok Bot, through Apple Health and Memory.fit.
The AI reads your workouts, sleep, heart rate and VO2 max, and can plan sessions. The Memory.fit iPhone app is not out yet, so join the waitlist for it.
What Apple's own AI does
Workout Buddy came with watchOS 26. It gives spoken motivation and feedback during a workout, using your workout data and fitness history. Apple says it works with Bluetooth headphones and needs an Apple Intelligence capable iPhone nearby. Reports at launch listed iPhone 15 Pro or newer, and English as the only language.
It talks to you while you train. It does not write a training plan or look at your week for you.
- Needs watchOS 26 and an iPhone with Apple Intelligence
- Works with Bluetooth headphones
- Spoken during workouts, English only at launch
Your Apple Watch data in the AI you already use
Memory.fit reads your watch through Apple Health. You connect Apple Health in the Memory.fit iPhone app, add Memory.fit to ChatGPT, Claude, Grok Bot, Muse, Dots or Grok, and the AI sees your data. The iPhone app is coming, so there is a waitlist for now.
Apple Health holds what your watch records, so the AI reads it as Apple Health sends it.
- Reads: workouts, sleep, heart rate, resting heart rate, HRV, VO2 max, steps, weight
- Compares your sleep with the sessions around it
- Plans sessions your AI saves in Memory.fit
- Works the same for any AI you connect
Which one to use
Workout Buddy is a voice in your ears during a run or ride. An AI of your choice is for the planning around it: your week, your sleep, your fuel. They do different jobs and can be used together.
