Some older Samsung watches can connect to an iPhone, but Galaxy Watch4 and newer Galaxy Watch models cannot be set up with iOS through Samsung. Compatibility depends on the exact watch model, and some features may be unavailable even on supported models.
Which Samsung watches work with iPhone?
Samsung’s compatibility guidance distinguishes older models from newer Wear OS watches. The following models are listed as supporting iPhone connection, subject to the requirements and regional caveats below.
| Watch or fitness band | Samsung-listed iPhone requirement | Support detail |
|---|---|---|
| Galaxy Watch (2018), Galaxy Watch Active, Galaxy Watch Active2 | iPhone 5 or later with iOS 9 or later | Listed by Samsung U.S.; Samsung Canada also lists these models. |
| Galaxy Watch3 | iOS 9 or later on iPhone 5 or newer | Listed in Samsung Canada’s guidance and compatibility table. |
| Gear Live, Gear S2, Gear S3, Gear Sport, Gear Fit 2, Gear Fit2 Pro | iPhone 5 or later with iOS 9 or later | Listed by Samsung U.S. |
| Galaxy Fit | iPhone 7 or later with iOS 10 or later | Samsung U.S. lists this higher minimum; Samsung Canada also identifies Galaxy Fit as connectable. |
| Galaxy Watch4 and later, including Watch5, Watch6, Watch7, Watch Ultra, Watch8, Watch9 and Watch Ultra2; Galaxy Fit3 | Not compatible with iOS | Samsung U.S. lists Watch4 through Watch7, Watch Ultra, Watch FE and Fit3 as incompatible. Samsung Canada’s September 11, 2026 table marks Watch4 through Watch9/Watch Ultra2 as unsupported. |

Why Galaxy Watch4 and newer models do not pair with iPhone
The dividing line is the watch generation and its operating system. Samsung says Galaxy Watch4 and later models use Wear OS and are not compatible with iOS devices; they cannot be set up using a Samsung app. Samsung Canada’s September 2026 compatibility table likewise marks newer generations through Watch9 and Watch Ultra2 as unsupported. This is not a setting that can be changed on the iPhone to make official setup work.

What works—and what may not—on an iPhone
For a supported older model, Samsung directs users to the appropriate Samsung Galaxy Watch or Galaxy Fit app from Apple’s App Store. Samsung cautions that some features and services may not be available when a watch is connected to iPhone. Its published material does not provide a complete feature-by-feature comparison for every supported watch, so do not assume that an iPhone pairing offers the same experience as a compatible Samsung phone.
How to connect a supported older watch
- Check the exact watch model and confirm that the iPhone meets Samsung’s listed minimum iPhone and iOS requirements.
- Open Apple’s App Store and install the Samsung app identified for that device: Galaxy Watch or Galaxy Fit.
- Open the app, select your watch model, and follow the on-screen setup instructions to pair it.
- If the app does not list the model or setup fails, consult Samsung’s model-specific instructions for your region rather than assuming that another app or workaround is supported.
Samsung notes that screens and settings may vary by region. Its Canadian setup guidance says third-party apps are not recommended or guaranteed for setting up unsupported Wear OS watches with iOS.

What to check before buying or setting one up
- Exact model: Names can be similar across generations. Verify the model number or full product name, not just “Galaxy Watch.”
- iPhone and iOS version: The listed minimums differ by model. For example, Samsung U.S. specifies iPhone 5/iOS 9 for several older watches, but iPhone 7/iOS 10 for Galaxy Fit.
- Local Samsung guidance: Support lists and qualification may differ by region, and Samsung says some models may still be incompatible even when they meet the stated requirements.
- App and feature expectations: Confirm that the required Samsung app is available and account for possible missing features or services.
- Older-model condition and availability: If considering an older compatible watch such as Galaxy Watch Active2, check the seller’s exact model and condition, as well as current app support. Compatibility does not establish that a particular listing is available or suitable.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
