Oura Ring 5 vs Samsung Galaxy Ring: Which Wins?
The Oura Ring 5 and the Samsung Galaxy Ring are the two best-known smart rings you can buy, and they take opposite approaches. The Oura Ring 5 (the latest ring from Finnish health-tracking firm Oura) charges a monthly membership but works on any phone; the Samsung Galaxy Ring (Samsung's first smart ring) has no subscription but is built for Galaxy phones. Which wins depends almost entirely on the phone in your pocket.

Samsung Samsung Galaxy Ring
Bottom line. The best no-subscription ring for Galaxy-phone owners who'll stay on Android.
Pros
- No subscription - every feature works for the life of the ring
- Wireless charging case included in the box
- Deep integration with Samsung Health on Galaxy phones
Cons
- Android-only in practice - no fully-supported iOS app
- Best features need a recent Galaxy phone (One UI 6.1+)
- Fewer sensors - no SpO2 or ECG
What's the real difference?
Three things decide this one. Phone platform: the Oura Ring 5 works fully on iPhone and Android; the Samsung Galaxy Ring is Android-only in practice, and its best insights need a recent Galaxy phone running One UI 6.1+ (Samsung's Android software layer). Cost model: both rings are £399, but Oura adds a mandatory £5.99/month membership for the full app, while Samsung charges nothing beyond the hardware. Sensors and accuracy: Oura's tracking is deeper and more independently validated, and it adds Blood Pressure Signals and Nighttime Breathing; the Galaxy Ring runs a more conservative sensor set with no SpO2 and no electrocardiography (ECG).
Samsung counters with one genuine hardware win: a wireless charging case in the box, which Oura does not match.
Subscription vs no subscription: which matters more?
Over three years, Oura's membership adds roughly £215 on top of the £399 ring - so the true cost gap is far wider than the identical sticker prices suggest. If you want to pay once and own every feature forever, the Galaxy Ring is the clear value choice.
The catch is that the saving only counts if you stay on a Galaxy phone. Switch to an iPhone, or even a non-Samsung Android handset, and the Galaxy Ring loses much of what makes it good - while the Oura Ring 5 keeps working exactly the same on whatever you move to.
