RingConn Gen 2 vs Oura Ring 4
Which should you buy? Our verdict on both, pulled from our full The Best Smart Rings: 4 Compared (and One to Skip) comparison.
The RingConn Gen 2 delivers a full feature set, a long battery, and no ongoing fee at a lower price, making it the smartest default for most people. The Oura Ring 4 is the runner-up and the accuracy champion, but only worth it if you accept its permanent membership.
RingConn Gen 2
Buy itThe subscription-free ring that undercuts everyone while adding sleep-apnea monitoring and a long battery.
- No subscription: every feature, including sleep-apnea monitoring, is unlocked permanently at purchase
- Long battery, with the maker rating about 10 to 12 days per charge (depending on ring size) plus an included case that extends total runtime dramatically
- Very light and thin titanium build that owners find comfortable for overnight wear
- Sleep-apnea monitoring is a wellness estimate, not a diagnosis, and extra sensing can shorten battery life
- The app and coaching layer feel less polished and less mature than the category leader's
Oura Ring 4
Buy itThe most refined sleep tracking and app experience in the category, if you accept an ongoing membership, billed monthly or yearly.
- Owners and reviewers rate its sleep-stage and resting-heart-rate trends among the most accurate of any ring
- The most mature app, with readiness, temperature-trend, and coaching insights built on years of algorithm refinement
- Works fully across both iOS and Android, with a multi-day battery
- A paid membership is needed for most insights, so the true cost keeps climbing after purchase
- Premium finishes push the hardware price into the top of the range
