Apple Health + AI Coaching
Apple Health already collects data from your Apple Watch, iPhone, and other apps. Our iOS app syncs all of it to your AI coach - workouts, heart rate, steps, sleep, and body measurements in one place. Sign up free on the web, then connect Apple Health from the app in about a minute.
Apple Health connects through our iOS app
Apple has no server-side API for Health data, so it syncs from your iPhone via the athletedata iOS app (currently in beta). Start free on the web here, link your account, and you'll get an invite to the app where you grant Health access. Everything else - Strava, WHOOP, Oura, Garmin and more - connects straight from the web dashboard.
data
- Apple Health aggregates data from your Apple Watch, iPhone, and third-party apps. One connection gives the AI access to all of it.
- Apple Watch's heart rate sensor is accurate to within 2-6 BPM during exercise according to a 2019 Stanford validation study. Good enough for meaningful zone analysis.
- The AI tracks resting heart rate trends over weeks. A steady decline in resting heart rate is one of the clearest signs your cardiovascular fitness is improving.
- If you use MyFitnessPal, Peloton, or other apps that write to Apple Health, that data flows through too.
What your coach does with Apple Health
Unified workout analysis
Apple Health collects workouts from Apple Watch and other apps. Your AI coach sees every session with duration, calories, heart rate zones, and distance. No more having data scattered across five different apps.
Heart rate and cardio fitness trends
The AI tracks your resting heart rate, walking heart rate, heart rate recovery, and VO2 max estimates over time. A faster heart rate recovery after exercise (how quickly your heart rate drops in the first minute) is a strong marker of cardiovascular fitness.
Sleep and daily activity monitoring
Apple Watch captures sleep duration and stages alongside daily steps, flights climbed, and active energy. The AI uses the full picture - not just your workouts - to assess whether your recovery matches your training load.
Body measurements and composition
Weight, body fat percentage, and other measurements logged in Apple Health are tracked over time. The AI correlates body composition changes with your training patterns to help you understand what's actually driving results.
Questions
How does Apple Health connect to the AI coach?+
Apple Health acts as a hub for data from your Apple Watch, iPhone, and compatible apps. Because Apple has no server-side API for Health data, it syncs through the athletedata iOS app rather than a web OAuth flow: sign up free on the web, open the Apple Health card on your dashboard to get a linking code and an app invite, then grant Health access in the app. From then on your workouts, heart rate, sleep, steps, and body measurements sync automatically.
What Apple Health data does the AI look at?+
Workouts, heart rate data (resting, active, recovery), VO2 max estimates, step counts, active and total calories, sleep duration and stages, body weight, and body fat percentage. It combines these into a complete coaching picture.
Do I need an Apple Watch?+
Not strictly, but it helps a lot. Without a Watch, you still get steps, flights climbed, and manually logged data from your iPhone. With a Watch, you add automatic workout detection, continuous heart rate monitoring, sleep tracking, and VO2 max estimates.
Does data from third-party apps come through?+
Yes. Any app that writes data to Apple Health (MyFitnessPal, Peloton, Nike Run Club, etc.) will have that data available to your AI coach. It's a good way to centralize data from multiple sources.
How do I connect Apple Health?+
Start free on the web and open integrations on your dashboard. The Apple Health card gives you a linking code and an invite to the athletedata iOS app (currently in beta). Install it, enter the code, and approve Health access on your iPhone. Your historical health data imports and new data syncs continuously after that.
