Google Health (Fitbit) + AI Coaching
Fitbit trackers, the Fitbit Air band, and Pixel Watch all live in the Google Health app now. It measures your training, sleep, and recovery. Your AI coach turns those numbers into decisions.
- Workouts, sleep stages, heart rate, nightly HRV, and weight sync automatically from any Fitbit device, the Fitbit Air band, or Pixel Watch via the Google Health API.
- Google folded the Fitbit app into the Google Health app in May 2026, and this integration is built on its new API, the long-term successor to the retired Fitbit Web API.
- Sleep and weight arrive in near real time through webhooks, so your morning recovery brief reflects last night, not two days ago.
- On Android, other apps that write to Health Connect (including Samsung Health) can feed the Google Health app, which brings that data to your coach through the same connection.
What your coach does with Google Health
Sleep stage analysis
Your coach receives each night's full stage timeline: deep, light, REM, and awake minutes. Consistently low deep sleep or fragmented nights change what the AI asks of you the next day, from intensity down to bedtime suggestions.
Nightly HRV trends
Fitbit measures HRV (RMSSD) in windows across the night. The AI averages them into a nightly value and tracks your baseline over weeks, reading multi-day drops as accumulating fatigue rather than reacting to single noisy nights.
Workout tracking
Runs, rides, walks, gym sessions, and everything else your device records lands in your training log with duration and heart rate. If you also use Garmin, Strava, or WHOOP, duplicate recordings of the same session are recognized and counted once.
Weight and body metrics
Weigh-ins logged in the Google Health app (or from a connected scale) reach your coach within minutes and feed long-term trend tracking alongside your training load and fueling conversations.
Questions
Which devices work with this integration?+
Every tracker that syncs to the Google Health app: all Fitbit trackers and smartwatches, the screenless Fitbit Air band, and Pixel Watch. If it shows up in your Google Health app, your coach can read it.
I use Samsung Health. Can my data reach the coach this way?+
Yes, on Android. Samsung Health shares data with Health Connect, and the Google Health app can read Health Connect and carry that data to its cloud. Connect Google Health on your athletedata dashboard, install the Google Health app on your phone, and allow it to read from Health Connect. A native Samsung Health integration is on the roadmap.
What happened to the old Fitbit integration?+
Google retired the Fitbit Web API in September 2026 and replaced the Fitbit app with the Google Health app. athletedata built directly on the new Google Health API, so nothing here depends on the retired platform.
How fresh is the data?+
Sleep and weight are pushed to us within minutes of your device syncing. Workouts arrive on an hourly schedule until Google adds push notifications for exercise, which they have announced.
How do I connect Google Health?+
The integration is in beta. Join the waitlist from the Google Health card on your integrations page and we'll email you when your access opens. Once enabled, you connect with your Google account in about 30 seconds, and recent history imports automatically.
