Is the Galaxy Fit3 compatible with iPhone?
Yes. The Samsung Galaxy Fit3 (SM-R390) works with iPhone through Fit3 Bridge, an independent app that connects to the band directly over Bluetooth. It isn't compatible with Samsung's apps: Galaxy Wearable doesn't exist for iPhone.
Why does Samsung say it isn't compatible with iOS?
Samsung sets up the Fit3 with Galaxy Wearable, which is Android-only. The iPhone app "Samsung Galaxy Fit" (formerly Gear Fit) only supports up to the Fit2. That's why the box says Android 10 or later and stores tell you it won't work. But the band itself uses standard Bluetooth: the limit was the app, not the hardware.
What works with iPhone?
- Pairing and first-time setup, even on a freshly reset band.
- Steps, distance, calories, heart rate, sleep, blood oxygen, floors, water and workouts in Apple Health.
- WhatsApp, Telegram, Messages or any app's notifications on the band, through an iOS 27 Shortcuts automation the app installs.
- Apple Music controls, weather, find my phone, and taking photos with the band's button.
- Settings: brightness, vibration, goals and heart rate alerts.
What doesn't work?
- Replying to messages from the band.
- Controlling Spotify or YouTube Music (iOS doesn't allow it for other apps).
- Using it with the app closed: Fit3 Bridge has to stay in the background. If you swipe it away, iOS drops the connection.
Which iPhones does it work with?
Any iPhone with iOS 17 or later: iPhone XS, XR, 11, 12, 13, 14, 15, 16, 17 and SE (2nd generation and later). Notifications from other apps need iOS 27.
How much does it cost?
Fit3 Bridge has a 3-day free trial with everything unlocked. If it's useful, it's a one-time purchase at your local App Store price, no subscription. It works with any Galaxy Fit3 you bought on Amazon, Best Buy or anywhere else, as long as it's model SM-R390.
