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.

Samsung aped iPhone filters, but served it better on the Galaxy S25
Using filters on the Samsung Galaxy S25 Ultra.

With the arrival of the Galaxy S25 series, Samsung introduced a bevy of camera-centric changes. Take for example the Galaxy S25 Ultra, which upgrades to a 50-megapixel ultrawide sensor, a new Spatio Temporal filter for blur reduction, 8K capture across all lenses, default 10-bit HDR recording, and more. But the company silently gave a massive boost to filters.

So far, users have only been able to pick a filter and capture media with the effect applied on top. There was no scope for fine-tuning the filter characteristics in real time. That limitation has finally gone to the grave with the Galaxy S25 series.

The Galaxy S25 has already broken records, and it’s not even out yet

The Samsung Galaxy S25 has proven so popular already, its pre-orders in South Korea have surpassed that of the Galaxy S23 series. Samsung claims 1.31 million Galaxy S25 phones have been pre-ordered between January 24 and February 3, while the previous S-series model managed 1.21 million pre-orders during the same period.

Samsung has also revealed how the series is performing at a device level. Perhaps unsurprisingly, the Galaxy S25 Ultra is the most preordered model in the range, with 52% of buyers opting for the most expensive S25 phone. The standard Galaxy S25 is in second place with 26% of the pre-orders, leaving the Galaxy S25 Plus in last place with 22% of the pre-orders.

Samsung is ushering in what will undoubtedly be an exciting year for smartphones with its new Galaxy S25 lineup. With all three models featuring a bespoke version of Qualcomm's most powerful silicon to date and a wealth of new Galaxy AI features, and the usual gorgeous AMOLED displays, they're more compelling than ever.

The Galaxy S25 might be the runt of the litter, but it's still a pocket-sized powerhouse — and it doesn't come cheap. At $800, you'll definitely want to shield it from the bumps and scrapes of life. That starts with a robust case, but don't forget the screen. After all, its the most fragile part of any phone, and the Gorilla Glass Victus 2 only goes so far. Adding some extra protection is a good idea, particularly if your phone spends time in a purse or backpack alongside keys and other abrasive items.
