How to sync Samsung Galaxy Watch with Apple Health

No official way for current models. Samsung states that Galaxy Watch4 through Watch8, Watch FE and Watch Ultra are not compatible with iPhone because they rely on Google Play services, and Samsung Health has no Apple Health export. Only older watches (Galaxy Watch, Watch Active/Active2, Watch3, Gear and Galaxy Fit models) work with an iPhone via Galaxy Wearable and Samsung Health for iOS, and what they pass to Apple Health is limited.

How to connect Samsung Galaxy Watch to Apple Health

4 steps on your iPhone, about two minutes.

Before you start

  • Galaxy Watch4 or newer: an Android phone for activation; on iPhone only through the unofficial Merge app
  • Older Galaxy Watch, Watch Active/Active2, Watch3, Gear S2/S3/Sport, Gear Fit2/Fit2 Pro, Galaxy Fit: Galaxy Wearable and Samsung Health apps from the App Store
  1. Check your model

    Galaxy Watch4, 5, 6, 7, 8, FE and Ultra cannot be paired with an iPhone officially. Older models (Galaxy Watch, Watch Active, Active2, Watch3) can use the Galaxy Wearable app on iPhone.

  2. Older watches: pair through Samsung apps

    Install Galaxy Wearable and Samsung Health from the App Store and pair the watch. Then in the Health app tap your profile picture > Privacy > Apps > Samsung Health and turn on the categories offered. Expect basic activity data at most.

  3. Newer watches: third-party bridge (unofficial)

    Activate the watch once with an Android phone. Install Merge on the watch from Google Play and Merge on the iPhone from the App Store, approve Bluetooth and Health permissions, and pair. Merge requires a subscription.

  4. Verify in Apple Health

    Open Health > Browse > Activity > Steps > Data Sources & Access and confirm the app appears as a source.

Bridge apps for Samsung Galaxy Watch

Independent apps that copy Samsung Galaxy Watch data into Apple Health. Prices as listed on the App Store on October 27, 2026.

  • Merge: Connect Android Watches

    Subscription: $3.99/month or $35.99/year (Basic), $5.99/month or $59.99/year (Pro), 14-day trial

    Unofficial; needs an Android phone for first activation

After setup

With Samsung Health for iOS, data reaches Apple Health only when the app syncs, and users report gaps. Merge runs as a background Bluetooth connection with the watch in range; Samsung features such as ECG, blood pressure and LTE activation do not work without an Android phone.

Avoid double-counting

If an iPhone and the watch both count steps, set the priority in Health > Browse > Activity > Steps > Data Sources & Access > Edit and drag the watch's app above iPhone. Samsung Health for iOS can also read iPhone steps from Apple Health, so avoid letting it re-count the same steps.

  5. Tap Done. Repeat for other data types you track with more than one device, such as Active Energy or Walking + Running Distance.

Samsung Galaxy Watch not syncing to Apple Health?

Galaxy Watch won't pair with my iPhone

Expected for Galaxy Watch4 and newer: Samsung lists them as not supported on iOS. Only older models work with Galaxy Wearable for iPhone.

Samsung Health on iPhone doesn't show my watch

The iOS Samsung Health listing supports only older wearables (Gear S2/S3/Sport, Gear Fit2/Fit2 Pro, Galaxy Fit/Fit-e/Fit2, Watch Active2, Watch3). Update both Galaxy Wearable and Samsung Health and the watch firmware.

Sleep from an older Galaxy Watch is not in Apple Health

Samsung Health for iOS passes very little to Apple Health. Users report that power-cycling the phone and watch and reopening Samsung Health sometimes restores syncing inside Samsung Health, but Apple Health support stays limited.

Steps are double-counted

Choose one steps source in Apple Health (Data Sources & Access > Edit) and don't let Samsung Health both read iPhone steps and write watch steps.

Merge drains the watch battery

A frequent App Store complaint. The developer says normal use should stay under 5%; check Merge's notification and sync settings.
