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.

The picks in detail
Oura Ring 5
Bottom line. The better all-rounder, and the only choice for iPhone users - if you accept the membership.
Pros
- Dramatically smaller and lighter than the Ring 4 (about 40% smaller, 2-2.69g)
- Longer 6-9 day battery, up from 5-8 days
- New Blood Pressure Signals and Nighttime Breathing metrics on top of Oura's class-leading sleep tracking
- Optional charging case holds around a month of power for travel
Cons
- Oura Membership at £5.99/month (or £69.99/year) is still required for the full feature set
- £399 entry price rises to £499 for premium finishes
- Blood Pressure Signals show cardiovascular patterns, not a clinical blood-pressure reading
- No screen and a fixed size - you commit to one finger and need a sizing kit first

Samsung Galaxy Ring
Bottom line. The best no-subscription ring for Galaxy-phone owners who'll stay on Android.
Pros
- No subscription - every feature on the device works for the lifetime of the ring with the included Samsung Health app
- Titanium build with a slightly concave outer profile that resists everyday scuffs visibly better than the flat-faced Oura 4
- Deep integration with Samsung Health and Galaxy phones - sleep, HRV, skin temperature, women's-cycle and AGEs Index all in one app you already use
- Wireless charging case included in the box (rare in the category - competitors ship a single puck) and rated up to 7 days battery life
- 10 ATM + IP68 water resistance so it can be worn in the shower and pool without removal
Cons
- Android-only in practice - there is no fully-supported iOS app, so iPhone owners should look elsewhere
- The most useful AI insights (My Vitality Score, advanced energy scoring) require a Galaxy phone running One UI 6.1+
- Sensor count is conservative - no SpO2, no ECG, no continuous skin-temperature stream, which means sleep-stage detail is less granular than Oura's stack
- Cycle and pregnancy tracking exists but is less feature-rich than the equivalent in Oura's app
- Sizes 5 and 6 carry visibly less battery than sizes 11–13, so small-finger users can expect closer to 5 days than 7

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.
Which should you buy?
Buy the Oura Ring 5 if
You're on iPhone or want the best tracking
