RingConn and Oura both make titanium smart rings that track sleep, heart rate, HRV, temperature, and blood oxygen. The big difference is how you pay. Oura charges a membership on top of the ring. RingConn has no subscription: you buy the ring, and every feature in the app is included.
The short answer: buy a RingConn Gen 3 ($349) if you don’t want another subscription, you want longer battery life, or you need a size 14 or 15. Buy an Oura Ring 5 ($399 plus $69.99 a year) if you want the most polished app, the deepest sleep and readiness insights, and the smallest, lightest ring. On a tighter budget, the RingConn Gen 2 Air is $199 with no subscription.

Best smart ring overall
Oura Ring 5
Oura's smallest, lightest ring, with the most polished sleep and readiness app; membership required.
Price and Subscription
This is the deciding factor for most people.
- Oura Ring 5 costs $399 for silver or black and $499 for gold, rose, stealth, and brushed silver. Oura Membership costs $5.99 a month or $69.99 a year, and the app’s scores and insights depend on it. New members get the first month free.
- RingConn Gen 3 costs $349, or $369 for metallic finishes, and there’s no subscription. It also comes with three months of Strava’s paid subscription.
Over three years, an Oura Ring 5 costs about $609 with an annual membership, and the RingConn Gen 3 still costs $349. That $260 difference grows every year you keep the ring.
Battery Life
RingConn lasts much longer. The Gen 3 is rated for up to 14 days, or about 10 to 12 days with vibration alerts turned on. The Oura Ring 5 is rated for 6 to 9 days, depending on ring size and use.
RingConn includes a wireless charging case with the Gen 3. Oura includes a charging dock and sells a $99 charging case, which holds up to five charges, separately.
Size, Weight, and Comfort
Both are thin titanium rings that are easy to sleep in. The Oura Ring 5 is Oura’s smallest yet: 6.09 mm wide, 2.28 mm thick, and from 2 grams. The RingConn Gen 3 is 2.3 mm thick and 2.5 to 3.5 grams, so they’re close, but Oura is a little lighter. RingConn’s inner shell is black, while Oura is metal inside and out.
RingConn comes in more sizes: 6 to 15, compared with Oura’s 6 to 13. If you need a large size, RingConn may be your only option. Order the brand’s sizing kit before you buy either ring, because smart-ring sizes don’t always match jewelry sizes, and the Gen 3 uses a different sizing system from earlier RingConn rings.
Sleep and Recovery
Both track sleep stages, resting heart rate, HRV, skin temperature, and blood oxygen overnight, and both give you daily sleep and recovery-style scores.
Oura’s app is the more polished of the two. Its Sleep, Readiness, and Activity scores are clear and well explained, and Oura adds features regularly, including an AI health companion, menstrual cycle insights, and lab-test panels. Oura has also published more validation research than most smart-ring makers.
RingConn covers the same basics and includes sleep, stress, activity, and women’s cycle predictions, all without a fee. Its app is simpler and less refined, but most people will find it does the job.
Health Features
- Blood pressure: neither gives blood pressure readings. RingConn Gen 3 offers vascular health trend insights. Oura Ring 5’s Health Radar adds blood pressure signals that flag possible signs of elevated blood pressure.
- Sleep apnea: RingConn Gen 3 and Gen 2 have sleep apnea pattern insights. Oura Ring 5 adds nighttime breathing signals to Health Radar.
- Vibration: the RingConn Gen 3 is one of the few smart rings that can vibrate. It uses vibration for health alerts and reminders, not for phone notifications or alarms. Oura has no vibration.
These are wellness features, not diagnoses. If either ring flags something, talk to a doctor.
The Cheaper RingConn: Gen 2 Air
The RingConn Gen 2 Air costs $199 with no subscription. It’s 2.0 mm thick, lasts up to 10 days, and comes in sizes 6 to 14. Compared with the Gen 3, it drops vibration alerts, vascular insights, and sleep apnea insights, and it uses a wired charging dock instead of a case. For basic sleep, heart rate, and activity tracking at the lowest total cost, it’s the best value in smart rings.
