Oura Ring 4 vs Samsung Galaxy Ring: Which Smart Ring Wins?

By Rowan Keller·Published November 11, 2026

Has been buying open-box and returned stock for over a decade, and built Warehouse Watcher to stop losing track of it.

Oura Ring 4 vs Samsung Galaxy Ring is the smart ring argument that fills r/ouraring and r/FitnessTrackers every week, and it is really an argument about a subscription. Both rings are titanium, both track sleep, heart rate and temperature, and both last about a week on a charge. The difference is what happens after you pay: Oura charges $5.99 a month for the insights that make the ring useful, while Samsung charges nothing, ever. The thesis: buy the Oura Ring 4 if you want the deepest sleep data and you use an iPhone, buy the Galaxy Ring if you use Android and refuse to rent your own health data back.

The short version: Oura wins on sleep insight depth, app maturity and cross-platform support. Samsung wins on comfort, weight and long-term cost. Neither ring is a fitness tracker, neither replaces a sports watch, and the right choice is mostly decided by the phone already in your pocket.

The subscription is the real price tag

The math is blunt. An Oura Ring 4 at its early-November Amazon price of $249 plus three years of membership at $69.99 a year costs $458.97 in total. A Galaxy Ring at its $324.99 late-October Amazon price costs $324.99 in total, and it never costs another cent. The ring with the lower sticker price ends up the more expensive buy within two years.

That is why the subscription is the most debated topic in r/ouraring, a community of about 177,000 members. Every buying thread lands on the same question: how do you feel about paying every month for features on a device you already bought? Decide before you buy, because the fee is not optional in practice: without membership you keep basic tracking and lose the readiness scores, trends and illness alerts that are the reason to own an Oura at all.

Sleep tracking: Oura goes deeper, Samsung scores shakier

Sleep is what both rings are for, and it is where Oura earns its fee. The Ring 4 tracks sleep stages, heart rate variability, skin temperature, blood oxygen and resting heart rate, then turns them into readiness and sleep scores with plain-language guidance. It also flags early illness from temperature and heart rate shifts, and estimates cardiovascular age, a feature no competing ring offers. Reviewers who wore both rings for weeks concluded that Oura wins on health insight depth.

The Galaxy Ring tracks the same core signals through Samsung Health and gives you an Energy Score each morning, plus sleep coaching and, since November 2026, a sleep apnea detection feature that received FDA clearance in July 2026. That is a genuine Galaxy Ring exclusive. But testers who wore both rings found Samsung's sleep scores the least consistent of the three major rings, sometimes dropping a full night's score by 10 to 20 points for no clear reason. Both rings estimate sleep from pulse and movement, they are not sleep labs, and they are best used for trends, not diagnoses.

Comfort, battery and everyday wear

You wear a ring all day and all night, so comfort decides whether it gets used or sits in a drawer. The Galaxy Ring wins this round clearly. It weighs 2.3 to 3.3 grams depending on size, against 3.3 to 5.2 grams for the Oura Ring 4, and its concave profile makes it feel smaller than it is. It is also narrower, 7 mm against Oura's 7.9 mm. Testers consistently call the Samsung the more comfortable ring of the two.

Battery is close enough to call a tie: Oura claims 5 to 8 days depending on size and settings, Samsung claims up to 7 days, and both charge in their own cases in about an hour. Neither ring has a screen, GPS or speaker, so neither does anything useful for workouts beyond basic automatic activity detection. If you want workout data, keep your sports watch; a ring is a sleep and recovery device that happens to count steps. Both rings are properly swim-proof, the Oura rated to 100 metres, the Galaxy Ring to 10 ATM plus IP68, and both demand a sizing kit before you order, because neither brand's sizes match standard jewellery rings.

Phone support: the iPhone dealbreaker

This is the round that ends the debate for half of all buyers. The Galaxy Ring does not work with iPhone, full stop. It needs an Android phone running Android 11 or newer, and some features, Double Pinch gestures and Find My Ring among them, only work on Samsung Galaxy phones. If you own an iPhone, this comparison is over: buy the Oura Ring 4, or buy a different ring entirely.

Oura works with both iPhone and Android, which is a quiet advantage in mixed households. Its app is also the more mature of the two, with years of algorithm development behind its readiness and illness detection, and integrations with more than 40 apps including Strava and Natural Cycles. Samsung Health is solid and improving, and it ties neatly into Galaxy Watches and Galaxy AI, but it is a Samsung-first world, and it shows the moment you step outside it.

Price and deals: both rings are in discount season

Both rings are in their discount season. The Oura Ring 4 launched at $349 in October 2024 and Amazon had it at $249 in early November 2026, its lowest price of the year, because the Ring 5 arrived in May 2026 and the older model is being cleared. On Amazon.ca, Silver Ring 4 models list from about CA$470. The Galaxy Ring launched at $399.99 in July 2024 and has spent most of 2026 on sale: $324.99 on Amazon in late October, $299.99 on Samsung's own site earlier in the year, and the CAD version is listed on Amazon.ca. Prices move daily, so treat any number here as a snapshot.

The verdict: Oura Ring 4 vs Samsung Galaxy Ring, who should buy which

Buy the Oura Ring 4 if you want the deepest sleep and recovery insights, you use an iPhone, or you live in a mixed iPhone and Android household. Buy the Samsung Galaxy Ring if you use a Samsung or other Android phone, you refuse to pay a monthly fee, or you want the lightest, most comfortable ring. If you are platform-free and price-sensitive, the Galaxy Ring is the cheaper buy over three years.
