How to Connect Galaxy Watch Ultra 2 to Your iPhone.

Samsung's dive-rated flagship: an 800mAh battery, a 5,000 nit screen, and the first Galaxy Watch to run a Qualcomm chip instead of an Exynos.
About the Galaxy Watch Ultra 2
Announced at Unpacked in July 2026 and on sale from 7 August at $699.99. Two things make it a real generational change rather than a refresh.
First, Samsung left Exynos. The Ultra 2 runs a Qualcomm Snapdragon SW6100 Wear Elite, a 3nm penta-core part, the first Qualcomm silicon in a flagship Galaxy Watch. Second, the battery jumped to 800mAh, up 35% on the original Ultra, while the case got 12% thinner at 10.7mm. The screen peaks at 5,000 nits, which is brighter than most phones.
It is also the first Galaxy Watch certified as a dive watch. Alongside 10ATM and MIL-STD-810H it carries EN13319 to 40 metres and IP69K, and Samsung has a diving app built with Mares coming later in 2026. Samsung raised its commitment with this model to five operating system upgrades and five years of security updates.

Connect in 3 Steps
Install Lynio Watch on your Galaxy Watch Ultra 2
From the Play Store on the watch. If Google sign-in will not work there, Lynio sends the app across as a signed bundle over Wi-Fi instead.
Follow the in-app pairing guide
Keep both on the same Wi-Fi, Bluetooth on, and leave the app open until pairing finishes.
What You Get After Pairing
| Works | Does not carry over |
|---|---|
| Notifications from your iPhone | Samsung Pay and Samsung Wallet |
| Calls, made and answered from the wrist | Samsung Health's phone app |
| Contacts synced from the iPhone | Bixby |
| Music playback control | Samsung Find |
| Workouts and health data written to Apple Health | |
| Dive rating, water temperature, GPS, every on-watch sensor |
Samsung's ECG reading is the one to check for yourself. Samsung ties it to the Samsung Health Monitor app on a Galaxy phone, so the sensor is on the watch but that specific reading depends on Samsung's own software.
Frequently Asked Questions
No. A Galaxy Watch is the one case where an Android phone is not needed at any point, including first-time setup.
Yes. EN13319 certification, 10ATM and IP69K all run on the watch's own hardware, so pairing to an iPhone through Lynio doesn't change any of it.
No. Both need Samsung's own phone-side software, which does not exist on iOS. The watch's own sensors and hardware controls still work through Lynio.
