No. You cannot use any Galaxy Watch with an iPhone. Samsung’s current support guidance says the Galaxy Watch4 and newer Wear OS models do not work with iOS. A small group of older Galaxy Watch models, including the Galaxy Watch3, was designed with iPhone compatibility, but even those come with functional limits, and their exact requirements depend on the model and your country.
Which Galaxy Watch models work with an iPhone
The dividing line is the watch generation, because the generations run on different software platforms. Older Galaxy Watch models run Samsung’s Tizen system. Galaxy Watch4 and later run Wear OS, which relies on Google Play services. Samsung says those services are not supported on iOS, so the newer watches cannot be paired with an iPhone through a normal setup.

The iPhone listings for the older models come from a regional Samsung page, not a worldwide one. Treat them as a starting point and confirm the exact model against Samsung’s support information for your country before you buy or set up.

A compatible listing does not mean the watch behaves the same way it does with an Android phone. Samsung’s developer documentation covers the limits for older watches, including a plain statement from its “iPhone Limitations for Galaxy Watch Apps” page, dated January 26, 2017: “Companion applications are not supported for iPhone.” That line applies to the Tizen-era watches, not to every Galaxy Watch, and it is the reason the platform split matters.

The same page explains the connection itself: “The connection between a Galaxy Watch and an iPhone is based on Bluetooth Low Energy (BLE), which has a lower bandwidth than Android devices.” In practice, data-heavy features such as audio or video streaming and map apps may not work properly over that link. Some standalone apps may still function when the watch connects directly to Wi-Fi or cellular, but that depends on both the watch and the app. Some companion-app programming interfaces are also unsupported on iPhone.
Samsung’s official material does not provide a complete feature-by-feature list for each model, country, iOS version, and app. Do not assume messaging, notifications, health tracking, payments, or any particular app will work the same way on an iPhone as on Android. Check the specific feature you need.

Requirements for older models
For the Galaxy Watch, Galaxy Watch Active, Galaxy Watch Active2, and Galaxy Watch3, Samsung Australia lists iPhone 5 or later running iOS 9 or later. That is a stated baseline for one region at the time of the listing. It is not a guarantee for every territory, and the sources do not establish whether newer iOS versions or newer iPhones are supported. If you are setting up a watch on a current iPhone, verify compatibility for your exact combination before relying on it.
How to check before you pair
- Confirm the exact model name. The Galaxy Watch3 is an older Tizen watch, while the Galaxy Watch4 and later are Wear OS, so a similar-sounding name can mean a different platform.
- Open Samsung’s compatibility or support information for your country and find the model listed there.
- Check your iPhone model and iOS version against the stated minimum for that listing. For the Australian listing, that means iPhone 5 or later and iOS 9 or later.
- List the features you need, such as notifications, messaging, fitness tracking, or specific apps, and check each one against the limitations above.
- If you are buying a used or older unit, check that the seller’s listing names the exact model and that the watch’s condition matches the description before you pay.
If you are considering an older model
A Galaxy Watch3 is the most recognizable older model that Samsung lists as iPhone-compatible, so it is the one most readers searching for an iPhone option will encounter. Availability, condition, and price vary by seller and region, and the official sources do not address them, so verify the listing yourself. Pick an older model only if its listed compatibility matches your iPhone and the features you need.

Galaxy Watch4 and newer models are a different case. They are built for Wear OS and Android phones, so an iPhone is not a supported partner for them under Samsung’s current guidance.
