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.

Start free, connect Google Health →

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.

How athletedata uses your Google Health data

When you connect Google Health, athletedata reads your workouts (sport, duration, distance, heart rate and calories), sleep and sleep stages, heart rate, heart rate variability, resting heart rate, weight and body fat. Access is read-only: we never write to or delete anything in your Google Health account.

We use this data only to provide the features you use: your AI coaching, a training plan that adapts to your recovery, and your training and health analytics. We share it only with the service providers that run athletedata, including the AI providers that generate your coaching (they do not train on it), and with your coach if you join a team. We never sell it, never use it for advertising and never use it to train AI models.

athletedata’s use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. You can disconnect in your dashboard, or revoke access at myaccount.google.com/permissions, at any time. The details are in our privacy policy.

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. Or skip the extra hop: the athletedata Android app connects Samsung Health directly.

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?+

Open your integrations page, tap Connect on the Google Health card and sign in with the Google account your Fitbit or Pixel Watch uses. It takes about 30 seconds, and recent history imports automatically.
