To sync a fitness tracker with Apple Health, enable Apple Health sharing in the tracker’s companion app, then authorize the specific data categories in Apple Health on your iPhone. The exact options depend on the tracker: compatibility and permissions do not guarantee that every device exports every type of data.
Before you start: confirm the tracker supports Apple Health
Apple Health can show data only from apps that integrate with it. Apple says you can check compatible apps in Health; if your tracker’s companion app is not listed, it may not support Health integration. Some apps also require you to turn on sharing in their own settings. Apple’s instructions for managing Health data access explain where to check.
Even when an app connects, it can write only the data types its maker supports. Check the tracker maker’s current export list if you need a particular category, such as sleep, heart rate, or workouts.
Set up the connection
- Enable sharing in the tracker app. Open the companion app and look for an Apple Health, Health, or data-sharing setting. Turn on the integration if it is offered. Menu names vary by app.
- Choose permissions in Apple Health. Open Health on your iPhone, tap your profile picture, then go to Privacy > Apps. Select the tracker app and enable the categories you want it to write. Apple’s permissions are category-specific, so allow only what you need. Review Apple’s Health access steps.
- Sync the tracker. Return to the companion app, sync the wearable, and let the app finish. The timing depends on the integration. Garmin, for example, says data transfers to Apple Health after a successful device sync. Garmin’s Apple Health support page describes its process.
- Check the result. In Health, open a relevant category such as Steps or Sleep and inspect the records and sources.
What to expect from specific integrations
Garmin Connect
Garmin’s guidance says Apple Health receives data after a successful Garmin device sync. If Garmin Connect is closed or in the background before that sync, transfer may wait until a successful sync occurs while the app is open. This is Garmin-specific guidance, not a general timing rule for all trackers. See Garmin’s instructions for current details.

Oura
Oura documents Apple Health integration on iOS for Gen2 and for Gen3 or later with an active membership. Its setup path is Oura App > Settings > Data sharing > Apple Health. You can also adjust its permissions in Apple Health under Privacy > Apps > Oura. Oura’s integration guide lists exports including 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 Oura steps do not contribute to the Stand ring because of an Apple limitation. These details apply to Oura’s integration; other trackers can export different categories or behave differently.

Fix missing, delayed, or conflicting data
- The app is missing from Health’s Apps list: It may not be compatible. Check the tracker maker’s current instructions and the app’s own integration settings.
- The app is listed, but no records appear: Confirm the relevant category is enabled both in the tracker app and in Health’s app permissions. Then run a fresh device sync.
- Only some categories appear: Check the tracker maker’s export list. A Health connection does not mean the app writes every category.
- Counts differ or look duplicated: Open the Health category, then choose Data Sources & Access. Review contributing apps and devices, reorder sources, or turn off a source. Apple Health uses source order when prioritizing similar data. Oura also notes that trackers’ different methods of classifying steps can produce different estimates. Oura’s guide describes making Oura the priority for Steps or disabling its Steps write permission.
- Garmin data is delayed: Open Garmin Connect and complete a successful device sync; Garmin says a transfer may wait if the app was closed or in the background before the sync.
Manage access and overlapping sources
Health lets you review which apps can write each category and change the source order for overlapping records. To adjust an overlap, open the affected category in Health and tap Data Sources & Access. Reorder sources to prioritize one, or disable a source if you do not want it contributing that category.
Apple describes HealthKit as a central repository for health and fitness data on iPhone and Apple Watch. Access is permission-based and can be managed by data type, so granting access to one category does not automatically grant access to all of them. You can review or revoke access in Health’s app settings. Apple HealthKit documentation and Apple’s Health privacy overview describe these controls.
