To sync a fitness tracker with Apple Health, enable sharing in the tracker’s companion app, then allow that app to write the specific data categories you want in Apple Health. The steps and available records vary by app: a connection does not mean every tracker or every data type is supported.
Before you start, check compatibility
Apple Health can show data only from apps that support its health-data sharing. Apple says that if a tracker app is missing from Health’s app list, it may not be compatible. Check the tracker maker’s current instructions as well: some companion apps require you to switch on sharing inside the app before Health can authorize it. Apple’s instructions for managing Health data explain how to find compatible apps and review their access.

Compatibility also applies to individual data types. An app might send steps or workouts but not sleep or heart rate. Apple Health permissions let you authorize categories the app offers; they cannot make the app export data it does not provide.
Set up the connection
- Enable sharing in the tracker app. Open the companion app and look for a setting named Apple Health, Health, or data sharing. Turn on its Apple Health integration if available. The label and location differ by brand.
- Choose Health permissions. On your iPhone, open Health, tap your profile picture, then go to Privacy > Apps. Select the tracker app and enable the categories you want it to write, such as Steps, Sleep, or Workouts. Apple’s Health data access guide covers this app-permission path.
- Sync the wearable. Open the companion app, connect or sync the tracker, and let the sync finish. For Garmin, the documented transfer to Apple Health follows a successful device sync; Garmin notes that transfer may wait if Garmin Connect is closed or in the background before that sync completes. Garmin support has brand-specific guidance.
- Check a category in Health. Open the relevant category—for example, Steps or Sleep—to see whether new records appear and which sources contributed them.
What different integrations may send
Each tracker maker defines its own exports, so check the app’s current supported-data list rather than assuming that all Health categories are included.

The exact menu labels and category coverage can vary; consult Garmin’s current instructions for your app and device.

Oura lists exports that include active energy, heart rate, height, mindful minutes, respiratory rate, sleep duration and stages, steps, weight, workout routes, and workouts. Oura says its workouts can contribute to Apple’s Move and Exercise rings, while its steps do not contribute to the Stand ring because of an Apple limitation. Those details describe Oura’s integration, not every tracker.

If more than one app or device writes to the same category, inspect the category’s sources in Health. Open a category such as Steps, tap Data Sources & Access, then adjust source order or turn off a source. Apple uses source order to prioritize similar data. Oura specifically recommends making Oura the priority source for Steps when its step records overlap with another wearable, or disabling Oura’s Steps write permission instead. Different trackers may classify movement differently, so step totals can vary even when both are working as designed.

Fix common sync problems
- The tracker app is missing in Health: It may not support Apple Health. Check the maker’s compatibility instructions and confirm sharing is enabled in the companion app.
- The app is listed, but no data appears: Check that the desired category is enabled both in the companion app’s integration settings and in Health’s app permissions. Then run a fresh wearable sync and wait for the companion app to finish.
- Only some categories appear: Review the tracker maker’s export list. Authorization is category-specific, and an app may not export every type of data.
- Counts look duplicated or different: Open the category’s Data Sources & Access list to reorder sources or disable a duplicate. For steps, different movement-classification methods can also produce different totals.
- Garmin records are delayed: Open Garmin Connect and complete a successful device sync; Garmin says a transfer may remain incomplete if the app is closed or in the background before that sync.
Review access and protect your privacy
Health permissions are granted by data type, not as one blanket authorization. Turn on only the categories you want the tracker app to share. To review or revoke access later, return to Health > profile picture > Privacy > Apps, select the app, and change its category permissions. Apple describes HealthKit as a central repository for health and fitness data on iPhone and Apple Watch, with access controlled through permissions. See Apple’s HealthKit documentation and its health-data privacy overview.
