Our verdict
Where it wins
- No subscription ever, unlike Oura's monthly fee, so the health data and features you get on day one stay unlocked for good
- Real-world battery life matches the roughly 14-day claim in reviews, meaning one charge every two weeks of normal use
- Titanium build rated to 10 ATM / 100m water resistance, plus a free sizing kit so you order the ring size that actually fits
- Broad sensor set (HR, SpO2, HRV, skin temperature, respiratory rate) plus vibration alerts
Where it loses
- Heart rate accuracy during intense exercise is reported as inconsistent by early reviewers
- The companion app is described as less polished and busier than Oura's, even though it's free
- Some Gen 3 features, like the vibration alarm, were still rolling out and not fully available at launch
The RingConn Gen 3 tracks sleep, heart rate, SpO2, and related health signals with close to two weeks of battery per charge, and it never charges a monthly fee, which makes it cheaper to own over time than subscription-based rings like Oura. Reviewers say the app is less refined than Oura's and heart rate readings can wander during hard workouts. It is a reasonable pick for someone who mainly wants sleep and recovery tracking without ongoing costs, but it is not a medical device.

More on the RingConn Gen 3
Common questions
Does the RingConn Gen 3 require a subscription?
No. RingConn's official product page and retailer listings state that all app features, including sleep, heart rate, and vascular health insights, are included with the ring at no extra monthly cost.
How accurate is RingConn Gen 3 sleep tracking compared to Oura?
No independent lab has published a direct head-to-head accuracy test. Reviewers note RingConn Gen 3 tracks similar metrics (sleep stages, HRV, SpO2, respiratory rate) and gets longer battery life, while generally rating Oura's app as more polished.
How do I find my correct ring size before buying?
RingConn ships a free plastic sizing kit (sizes 6-15) before your actual ring order. You wear the sizer for a day or two, then submit your chosen size through your RingConn account before the real ring ships.
