Yes—but only selected older Samsung watches officially connect to an iPhone. Galaxy Watch (2018), Galaxy Watch Active, Active2, and Galaxy Watch3 are among the supported models. Galaxy Watch4 and later, along with Galaxy Fit3, are not compatible with iOS under Samsung’s published guidance. Even with a supported older watch, some features may be unavailable.
Which Samsung watches work with an iPhone?
The model generation is the key distinction. Samsung’s US and Canada support pages identify some older watches as iPhone-compatible, while its guidance rules out Galaxy Watch4 and later Wear OS watches for official iOS setup.
| Samsung device | Samsung’s iPhone guidance |
|---|---|
| Galaxy Watch (2018), Galaxy Watch Active, Galaxy Watch Active2, Galaxy Watch3 | Compatible with iPhone 5 or later running iOS 9 or above, according to Samsung US. Samsung Canada identifies these older families for setup with the Galaxy Watch app. Samsung US compatibility guidance; Samsung Canada setup guidance. |
| Galaxy Fit | Samsung US lists iPhone 7 or later running iOS 10 or above as compatible. Use the Galaxy Fit app. Samsung US compatibility guidance; Samsung Canada setup guidance. |
| Gear Live, Gear S2, Gear Fit2, Gear S3, Gear Sport, Gear Fit2 Pro | Samsung US lists these older devices among those compatible with iPhone 5 or later on iOS 9 or above. Check the exact device and whether its app remains available for your phone. Samsung US compatibility guidance. |
| Galaxy Watch4, Watch5, Watch6, Watch7, Watch Ultra, Watch FE | Not compatible with iOS under Samsung’s US guidance because these models rely on Google Play services that iOS does not support. Samsung Canada says Wear OS watches such as Galaxy Watch4 and later cannot be set up with iOS using a Samsung app. Samsung US compatibility guidance; Samsung Canada setup guidance. |
| Galaxy Fit3 | Samsung US explicitly lists it as incompatible with iOS. It is not an iPhone-compatible alternative to the older Galaxy Fit. Samsung US compatibility guidance. |
| Gear, Gear 2, Gear S, Gear Fit | Samsung US says these models are not supported on iOS. The Gear name alone does not establish compatibility. Samsung US compatibility guidance. |
What does iPhone compatibility mean in practice?
Compatibility means a supported watch family has an official Samsung app and can be connected to an iPhone under the stated baseline. It does not mean every watch feature works as it would with a Samsung Galaxy phone. Samsung warns that some features and services may not be available when an older watch is connected to an iPhone.

Third-party apps are not official substitutes
Samsung Canada notes that third-party apps may offer limited connection options for newer Wear OS watches, but Samsung does not recommend or guarantee their performance, feature support, or security. A workaround should not be treated as Samsung-supported setup or as a promise that a Galaxy Watch4 or later will work with an iPhone. Samsung Canada setup guidance.
Check your iPhone and iOS version
Samsung’s published baselines vary by watch family. For Galaxy Watch (2018), Galaxy Watch Active, and Galaxy Watch Active2, Samsung US specifies iPhone 5 or later with iOS 9 or above. For Galaxy Fit, it specifies iPhone 7 or later with iOS 10 or above. Samsung also warns that connections may be unstable on iPhone 6S and 6S+ running iOS 10 or later. These are Samsung’s stated requirements; verify the exact model and current app availability for your iPhone and software version. Samsung US compatibility guidance.

How to set up a supported older watch
- Install the correct Samsung app from the App Store: Galaxy Watch for supported Galaxy Watch models, or Galaxy Fit for Galaxy Fit devices.
- Open the app and select your watch or fitness band from the device options.
- Follow the on-screen instructions to complete connection and setup.
Samsung Canada describes this process for supported devices and cautions that some features and services may not be available with an iPhone. Samsung Canada setup guidance.
How to decide before you pair
- Find the exact model name and generation; “Galaxy Watch” or “Gear” alone is not enough.
- Check whether Samsung lists that model as iPhone-compatible, rather than assuming a newer generation will work because an older one does.
- Confirm that your iPhone and iOS version meet Samsung’s stated baseline for that family.
- Check whether the features you need are available on iPhone; pairing support does not guarantee feature parity.
- For older devices, confirm the relevant Samsung app is currently available in the App Store for your region.
Samsung’s official compatibility and setup information is published for the US, Canada, and UK and may differ by market. Confirm your precise combination against current Samsung support guidance before relying on a connection. Samsung US; Samsung Canada; Samsung UK.
