Does Samsung Galaxy Watch 4 Work with iPhone?

Name: Google Pixel Watch 4
Brand: Google
Availability: PreOrder
Rating: 4.8 (1250 reviews)

No, the Samsung Galaxy Watch 4 does NOT work with iPhone or iOS devices. It requires an Android phone running Android 6.0 or higher.

Why No iPhone Support

Apple's Restrictions: iOS limits Bluetooth pairing to Apple Watch for smartwatches and blocks third-party wearable integration.
WearOS Platform: WearOS is designed primarily for the Android ecosystem, with the Galaxy Wearable app requiring Android permissions.
Business Decision: Samsung focuses on Android/Galaxy ecosystem users.

What Doesn't Work with iPhone

iPhone users cannot:

Pair the watch via Bluetooth
Receive notifications
Make or receive calls
Reply to messages
Install or manage apps
Sync health or fitness data
Even perform initial setup

The watch is completely non-functional with iPhone - this is total incompatibility, not a partial limitation.

Alternatives for iPhone Users

Apple Watch (Best Option): Apple Watch SE 2 ($249, budget-friendly), Apple Watch Series 9 ($399, current flagship), or Apple Watch Ultra 2 ($799, premium/rugged).
Other iOS-Compatible Options: Fitbit Sense 2 / Versa 4 (good fitness tracking), Garmin watches (excellent for fitness, long battery), or Amazfit GTR 4 (budget-friendly with basic features).

If You Have Both Phones

If you own both iPhone and Android:

Pair with Android phone for full functionality
LTE model can work independently after initial Android setup
Cannot pair simultaneously with both phones
Switching phones requires factory reset

Will Samsung Add iOS Support?

Unlikely. WearOS platform is designed for Android, Apple restricts third-party wearables on iOS, and Samsung has not announced any plans for iOS support.

Before You Buy

Verify your phone's operating system in Settings About. If you have an iPhone, buy an Apple Watch instead - it's the best smartwatch experience for iOS users.
