You’re standing in the electronics aisle, or maybe you’re scrolling through a late-night tab spree, and you see it. The Samsung Galaxy Watch 7—or maybe that beefy, rugged Galaxy Watch Ultra—is just sitting there looking sleek. Then you look at the iPhone 15 or 16 in your hand. You think, "I want that watch, but I love this phone. Can I make this relationship work?"
Honestly? It's complicated.
Back in the day, Samsung and Apple at least tried to play nice. You could download an app, sync up an old Galaxy Watch 3, and go about your business. But things changed. Specifically, things changed when Samsung moved to Wear OS (the Google-powered software) starting with the Galaxy Watch 4. Since then, the "official" answer from Samsung is a hard no for anything modern. But if you’re a tinkerer or someone who just wants to know if there's a workaround, the reality is a bit more nuanced.

The Samsung Watch and iPhone Compatibility Wall
Let’s get the bad news out of the way first. If you bought a Samsung Watch and iPhone hoping they would work like peanut butter and jelly, you’re going to be disappointed.
Samsung’s latest lineup—the Galaxy Watch 4, 5, 6, 7, and the Ultra—all run on Wear OS. This software is built on a foundation of Google Play Services. Since Apple doesn't allow Google Play Services to run deep in the guts of iOS, these watches simply will not pair with an iPhone through the official Galaxy Wearable app. You can try to open the App Store on your iPhone and search for it, but you'll only find the "Legacy" version that supports older Tizen-based watches.
It's a bummer. It’s basically a walled garden meeting a "no trespassing" sign.
- Galaxy Watch 7 & Ultra: Absolutely no official iOS support.
- Galaxy Watch 6 & Classic: Same story—Android only (specifically Android 11.0+ with 2GB RAM).
- Galaxy Watch 4 & 5: Nope.
- Galaxy Watch 3 & Older: These actually do work. They use Samsung’s old Tizen OS, and the "Samsung Galaxy Watch (Gear S)" app is still sitting on the iOS App Store.
Why did they kill the connection?
It wasn't just a random act of spite. By moving to Wear OS, Samsung gained access to a massive library of Google apps—Maps, Assistant, and the Play Store. That move required a deep integration with Android that iOS just doesn't permit. Apple keeps its "iMessage and Health" secrets locked tight, and Google needs its own "Play Services" to make the watch's brains function. They’re like two people who speak different languages and refuse to use a translator.
Is There a Way Around It? Sorta.
I’ve seen people on Reddit and various tech forums trying to use third-party "bridge" apps like Merge. These apps try to act as a middleman, pushing notifications from your iPhone to an "unsupported" watch via Bluetooth.
Does it work? Kinda. But it’s a janky experience. You might get a notification that you have a text, but you won't be able to reply. You might see your heart rate on the watch, but it won't sync to Apple Health. You’re basically turning a $600 Ultra smartwatch into a $30 "dumb" watch that happens to have a really nice screen.

And honestly, if you're spending that kind of money, you deserve better than "kinda works."
The "Tizen" Loophole
If you are absolutely dead-set on the Samsung aesthetic but refuse to leave the iPhone, you can hunt down a Galaxy Watch 3 or a Watch Active 2 on eBay. These older models still sync with iPhones. You'll get:
- Basic notifications.
- Step tracking.
- Heart rate monitoring (synced to the Samsung Health app on iPhone, not Apple Health).
- Changeable watch faces.
But keep in mind, these watches are getting old. The batteries are tired, and the software hasn't seen a meaningful update in ages. It’s like buying a vintage car—it looks cool, but don't expect it to have CarPlay.
Samsung Watch and iPhone: The Missing Features
Let’s say you do manage to get a connection via a third-party app or an older model. What are you actually missing? It’s a long list.
Samsung Wallet is a no-go. You can't pay for your morning latte with your wrist if you're on an iPhone. Bixby or Google Assistant? Forget about it. They need a data handshake with an Android phone to process your voice. Even the advanced health stuff—like the ECG (Electrocardiogram) or Blood Pressure monitoring—is locked behind the Samsung Health Monitor app, which only exists on Samsung Galaxy phones.
It’s not just an "iPhone vs. Samsung" thing; it's often a "Samsung Phone vs. Everything Else" thing. Even Google Pixel users can't use every single feature of a Galaxy Watch 7 without some side-loading gymnastics.
Better Alternatives That Actually Work
If you’re an iPhone user and you just can’t stand the "rectangular" look of the Apple Watch, you have other options that don't involve hitting a brick wall.
1. Garmin (The Rugged Choice)
Garmin is the king of cross-platform support. Whether you have an iPhone 18 Pro Max or a Galaxy S26, a Garmin watch like the Fenix 8 or the Forerunner 970 will work perfectly. You get 20+ days of battery life, which puts both Apple and Samsung to shame. Their app, Garmin Connect, syncs beautifully with Apple Health.
2. Amazfit
If you want the round look of a Samsung watch without the price tag or the compatibility headaches, look at the Amazfit GTR series. They look premium, they have amazing AMOLED screens, and their Zepp app works flawlessly on iOS. Plus, they’re way cheaper.
3. Google Pixel Watch (Wait, No)
Just a heads up: Don't get confused and think the Pixel Watch will work because Google is "more open." The Pixel Watch is also strictly Android-only. Stick to Garmin, Fitbit, or Polar if you want a high-end experience on an iPhone that isn't made by Apple.

What Most People Get Wrong About This Combo
People often think that because a watch has Bluetooth, it should work. "It’s just data, right?"
Not really. Modern smartwatches aren't just Bluetooth accessories; they are tiny computers that require a shared ecosystem to handle security, encryption, and health data privacy. When you pair an Apple Watch to an iPhone, they share a "secure enclave." Samsung does the same with its "Knox" security. These two systems are designed to be impenetrable, which unfortunately means they are also impenetrable to each other.
A Note on LTE Models
Some people try to bypass the phone entirely by getting a Galaxy Watch Ultra with LTE. They think, "I'll just give the watch its own cellular plan and use it as a standalone device."
While you can technically use an LTE watch without a phone nearby, you still need an Android phone to set it up initially. You can't activate the eSIM on a Samsung watch using an iPhone. You’d have to borrow a friend’s Samsung, set it up, and then... well, you still wouldn't get your iPhone's texts or calls forwarded to it. It’s a mess.
Real-World Advice: Stop Trying to Force It
Look, I get it. The Galaxy Watch Ultra is a gorgeous piece of hardware. That "Squircle" design and the titanium finish are tempting. But if you’re using an iPhone, you’re paying for a premium experience that you are essentially throwing away by trying to use a Samsung wearable.
If you want the best possible experience, here is the hard truth:
- iPhone User? Buy an Apple Watch Series 11 or the Ultra 3. The integration (unlocking your Mac, finding your phone, Siri, iMessage) is unbeatable.
- Hate Apple Watches? Buy a Garmin. You’ll get the round face, the data, and the durability without the software headache.
- Have to have Samsung? Switch to a Galaxy S25 or S26. The grass is pretty green over there, too.
Your Next Moves
If you already have a Samsung Watch and just switched to an iPhone, don't throw the watch in a drawer just yet.
- Check your model: If it’s a Watch 3 or older, download the Samsung Galaxy Watch (Gear S) app from the App Store and see if you can live with the limited features.
- Trade it in: Both Apple and Samsung have aggressive trade-in programs. You can often get a decent credit for a Galaxy Watch when buying an Apple Watch, or vice-versa at Best Buy.
- Sell it on Swappa or Back Market: These watches hold their value reasonably well. Sell the Samsung watch and use the cash to buy a used Apple Watch Ultra—it'll save you hours of frustration.
Trying to bridge the gap between a Samsung Watch and iPhone in 2026 is like trying to use a Mac keyboard on a Windows machine—you can get the keys to type, but the shortcuts will never feel right. Save yourself the trouble and stay within the ecosystem that actually wants your devices to talk to each other.
