This story is part of our Samsung Galaxy Unpacked 2026 coverage

The Samsung Galaxy Watch Ultra is official after Samsung’s Galaxy Unpacked event in Paris this week. The Galaxy Watch Ultra launched alongside the Galaxy Watch 7 and Samsung’s new foldables — the Fold 6 and Flip 6. It was also showcased along with the Galaxy Buds 3 and the Samsung Galaxy Ring. There weren’t big surprises here, with the Galaxy Watch Ultra largely being the device that was rumored in the lead-up to the event.

With its release, the Galaxy Watch Ultra is now the main competitor to the Apple Watch Ultra 2, with its 1.5-inch Super AMOLED sapphire glass screen, Exynos W1000 processor, and larger 590mAh battery. But for all the similarities it has to Apple’s Ultra smartwatch, does the Galaxy Watch Ultra actually work with the iPhone? Here’s what you need to know.

Does the Galaxy Watch Ultra work with the iPhone?

The Galaxy Watch Ultra does not work with any iPhone model. That’s not surprising since the latest Galaxy Watches, including the Galaxy Watch 4, Galaxy Watch 5, and Galaxy Watch 6, were all incompatible with the iPhone. This is because Samsung moved away from its Tizen operating system, and all these smartwatches, including the Galaxy Watch Ultra, require Google Play Services to function — which iPhone owners are unable to access.

Again, none of this should be a surprise. There’s usually very little cross-compatibility between Android and iOS when it comes to accessories. The OnePlus Watch 2 doesn’t work with an iPhone since it requires the use of the OHealth app. Similarly, while the AirPods do work with Android devices, many features are missing, including easy pairing, spatial audio, Find My tracking, Auto EQ, and more.

If you’re an iPhone owner who wants to use a Samsung smartwatch for whatever reason, you’ll need to get an old device like the Galaxy Watch 2 Active or Gear S3. However, most iPhone users will be better off getting an Apple Watch, like the Apple Watch SE, Apple Watch Series 9, or Apple Watch Ultra 2. They’ll give you a better experience with the full ability to use all the health and fitness tracking features.

The Galaxy Watch Ultra should work with any Android phone with Android 8.0 and higher and a minimum of 1.5GB RAM. Naturally, it should also work with most, if not all, Samsung phones, including the latest Galaxy Z Fold 6 and Galaxy Z Flip 6. In fact, you’ll probably be able to get a bundle deal for both devices. If you use the Watch Ultra with a non-Samsung phone, you’ll need to download the Samsung Wearable and Samsung Health apps to take full advantage of features and get complete control over watch faces and settings.

The Galaxy Watch Ultra features IP68 water and dust resistance, meaning it can withstand water immersion. It’s rated 10ATM waterproof up to 50 meters and has a MIL-STD-810H rating, meaning it survived a battery of lab tests for durability. It’ll come running Samsung One UI Watch 6.0 and support Bluetooth 5.3, dual-band Wi-Fi, NFC, and GPS dual frequency.

You can preorder the Samsung Galaxy Watch Ultra now for $650.

The wearable on your wrist can predict blood pressure crisis events days in advance
A hypertensive crisis can lead to acute organ damage, and the abrupt spikes in blood pressure are also linked to stroke, kidney damage, fluid backup in the lungs, and heart attack. Research says wearable devices can provide a warning 3 days in advance.

In the domain of wearable devices, we have reached a stage where they are available in a variety of form factors. You can go with a smartwatch, something a little more subtle like a smart band without a screen, or even a smart ring. And as the form factors have continued to evolve, so have the capabilities and the sensing hardware. What started with basic light-based heart rate tracking has now reached a stage where smartwatches are capable of tracking multiple metrics, such as taking electrocardiogram readings, tracking sleep, looking for signs of sleep apnea, or even detecting spikes in blood pressure levels.

Now, fresh research courtesy of the American Heart Association claims that these mass-market wearable devices can help predict episodes of dangerously high blood pressure, or hypertensive crisis, up to three days in advance. The research was conducted over a period of 12 months and involved more than 4,000 participants living with stage 2 high blood pressure.

Wear OS is borrowing your phone’s status bar so you never lose track of time
Your smartwatch is finally getting the one thing it was weirdly missing.

If you have ever opened an app on your Wear OS smartwatch and had no idea what time it was, Google is working on a fix. In October, the company launched a Wear OS canary emulator inside Android Studio. It lets developers try out new features and design tweaks well before Google ships them to anyone’s wrist.

The biggest addition in this build is a status bar that never leaves. It lives at the top edge of your round watch face, floats above whatever app you have open, and keeps the clock and your watch’s status icons in view.

Samsung's first AI-powered smart glasses are finally getting closer to store shelves. According to a new report from South Korea's ChosunBiz, the company is planning to launch its Intelligent Eyewear in mid-December, and if you're waiting to get your hands on them outside the US or South Korea, you might be disappointed.

For those catching up, we reported earlier in October that Samsung was planning a November launch. However, the latest report suggests the release has been pushed back by a few weeks. Samsung hasn't officially confirmed the new date, and there's still no word on how much the glasses will cost.
