Samsung Galaxy Ring Review: The Smart Ring That Actually Works

Smart rings have been a thing for a while now. The Oura Ring has been the gold standard since 2015. But when Samsung announced the Galaxy Ring at their Unpacked event earlier this year, it felt like a different proposition. A smart ring from a company that already makes phones, watches, and earbuds — it could either be perfectly integrated or a mess of proprietary features nobody asked for.

I've been wearing the Galaxy Ring for two weeks. Spoiler: it's really good. But it's not for everyone.

First Impressions: It's Smaller Than You Think

The Galaxy Ring comes in three colors (titanium black, silver, and gold) and sizes 5 through 13. I got size 8 in silver. It weighs about 3 grams — basically nothing. You forget you're wearing it after five minutes.

The design is minimalist. It's a smooth titanium band with a slight concave shape on the inside where the sensors sit. No visible buttons or screens. It's water resistant to 10 ATM (100 meters), so you can swim with it. I wore it in the shower without issues.

The ring comes with a sizing kit — a plastic dummy ring you wear for a day to find your size. Important: don't skip this. A ring that's too loose will slide around and give inaccurate readings. Too tight and it'll be uncomfortable. I went with the size that fit snugly on my index finger, but could also work on my middle finger. That's the sweet spot.

What It Tracks (and How Well)

The Galaxy Ring tracks heart rate, skin temperature, steps, sleep stages, and blood oxygen. It also has Samsung's BioActive sensor (same as the Galaxy Watch) for more accurate heart rate monitoring. The ring uses photoplethysmography (PPG) — basically, it shines light through your skin to measure blood flow.

I compared its readings to my Apple Watch (which I wore on the other wrist) for a week. The step counts were within 2% of each other. Heart rate during rest was nearly identical. During exercise, the ring lagged slightly behind the watch — maybe 5 seconds — but that's expected for a finger-based sensor versus wrist-based. For daily tracking, it's more than adequate.

Sleep tracking is where the ring shines. Because it's on your finger, it's less intrusive than a watch. I barely noticed it at night. The sleep stages (light, deep, REM) matched pretty well with what my Apple Watch reported. The skin temperature sensor is interesting — it detected a 0.5°C rise on a day when I was starting to get a cold. Useful, but not a game-changer.

Battery Life: The Killer Feature

The Galaxy Ring's battery lasts about 7 days on a single charge. That's huge. My Apple Watch needs charging every 36 hours. With the ring, I put it on the charging cradle (a small, puck-shaped charger) for 20 minutes while I shower, and it's good for another two days.

The charging case is compact — about the size of a lip balm tube — and holds two full charges. So you can go weeks without plugging anything in. This alone might be enough reason to choose the ring over a watch if you hate charging devices.

Samsung Health Integration: The Real Reason to Buy In

The ring works with Samsung Health, which is already one of the best health tracking platforms. If you have a Samsung phone, the integration is seamless. The ring automatically syncs data, and Samsung Health presents it in a clean dashboard. You get a "vitality score" each morning based on your sleep, activity, and heart rate variability. It's similar to Oura's readiness score.

But if you don't have a Samsung phone, the experience is limited. The ring works with Android 11+ devices (including Pixels and OnePlus), but some features — like the find-my-ring function and Samsung Wallet payments — are Samsung-exclusive. No iOS support at all. If you're an iPhone user, look at the Oura Ring instead.

Where It Falls Short

The ring has no display. That's by design, but it means you can't check your stats at a glance. You have to open the app. It also doesn't have GPS, so for outdoor runs, you'll need your phone for accurate distance tracking.

The gesture controls are a nice idea but limited. You can double-tap the ring to dismiss an alarm or take a photo (if you're using a Samsung phone). But it's not as useful as it sounds. I stopped using it after a few days.

Most importantly: the ring isn't a fitness tracker in the way a Garmin or Apple Watch is. It's not designed for real-time workout tracking. You can start a walking or running workout from the app, but the ring doesn't have haptic feedback or voice prompts. If you're training for a marathon, get a watch. If you want to understand your sleep and daily activity better, the ring is perfect.

Price and Value

The Galaxy Ring costs $399. That's $50 more than the Oura Ring Gen 4, but the Galaxy Ring doesn't require a subscription. Oura charges $5.99/month for advanced insights. Over three years, the Galaxy Ring saves you about $215. That's significant.

If you're already in the Samsung ecosystem — Galaxy phone, Galaxy Watch, Galaxy Buds — the ring is a no-brainer. It's a seamless addition to your health tracking. If you're not, the Oura Ring is still excellent and works with iPhone too.

I'm keeping mine. It's replaced my Apple Watch for sleep tracking, and I wear it alongside my watch during the day. The battery life alone makes it worth it. If Samsung adds a display in a future version, it could be the ultimate wearable. For now, it's a very good first attempt.
