Some older Samsung smartwatches can pair with an iPhone, but Galaxy Watch4 and later models cannot be set up with iOS through Samsung. Compatibility depends on the exact model, and supported older watches may not offer every feature or service when connected. Check Samsung’s current requirements for your region before buying or setting up a watch.
Which Samsung watches work with iPhone?
Samsung’s support information distinguishes older models from newer Wear OS watches. Its U.S. compatibility page lists several older Galaxy Watch and Gear devices for iPhone use, while Samsung Canada’s setup guidance identifies select earlier Galaxy Watch models and Galaxy Fit as connectable through Samsung apps.

Why newer Galaxy Watches do not pair with iPhone
The deciding difference is the watch generation and platform. Samsung says Galaxy Watch4 and later use Wear OS and are not compatible with iOS. Its Canadian compatibility table also marks the Watch4, Watch5, Watch6, Watch7/Watch Ultra, Watch8, and Watch9/Watch Ultra2 generations as unsupported. The cutoff is not simply whether a watch has “Galaxy Watch” in its name: some earlier models are listed for iPhone, while later ones are not.

Samsung Canada puts the distinction plainly: “While select earlier models support iPhone connection, some features and services may not be available.” It also says newer Wear OS watches “are not compatible with iOS devices and cannot be set up using a Samsung app.” Both statements come from Samsung Electronics Canada’s setup guidance, updated March 20, 2026.
What to check before setting up an older compatible watch
- Identify the exact model. Check the model name and number on the watch or its original packaging. Similar product names do not guarantee the same compatibility: Galaxy Fit is listed for iPhone in some Samsung support material, but Galaxy Fit3 is not.
- Check your iPhone and iOS version. For the older Galaxy Watch models listed by Samsung U.S., the stated minimum is iPhone 5 with iOS 9. Galaxy Fit has a higher stated minimum: iPhone 7 with iOS 10. Other listed Gear products use the iPhone 5/iOS 9 minimum.
- Install the app Samsung specifies for that watch. Samsung Canada directs users to the Samsung Galaxy Watch or Galaxy Fit app from Apple’s App Store, depending on the device. Select the watch model in the app and follow its setup instructions.
- Confirm local support and app availability. Samsung notes that screens and settings may vary by region, and its compatibility material warns that some models may still be incompatible even when listed requirements are met.
What may be limited when a Samsung watch is paired with iPhone?
A successful connection does not mean every watch feature or service will work. Samsung explicitly warns that some features and services may be unavailable, and it does not provide a complete iPhone feature-by-feature matrix for every older model in the cited guidance. Check the support instructions for your exact watch rather than assuming it will behave like the same watch paired with a Samsung phone.

Can you use a Galaxy Watch4 or later with iPhone through another app?
Samsung does not support iOS setup for Galaxy Watch4 and later. Third-party apps may offer limited connection options, but Samsung does not recommend or guarantee them; they should not be treated as a supported substitute for compatibility.

Should you buy an older Galaxy Watch to use with an iPhone?
Only consider an older model after confirming its exact model number, your iPhone’s iOS version, and the current availability of the required Samsung app. Galaxy Watch Active2 is one older model Samsung lists as compatible, but it is not a current-generation watch. For any used or remaining-stock listing, verify its condition and that the model on offer is the iPhone-compatible version. If you want a Samsung watch with officially supported iPhone setup, Samsung’s cited guidance does not list Watch4 or later as an option.
