Oura Ring 5 vs RingConn Gen 3: Which Is Better?
The Oura Ring 5 and the RingConn Gen 3 sit at opposite ends of the smart-ring value scale. The Oura Ring 5 (the latest ring from Finnish firm Oura) has the most trusted tracking but charges a monthly membership; the RingConn Gen 3 (from smart-ring maker RingConn) costs less, charges no fee, lasts far longer per charge and is swim-proof. For value-focused buyers, this is the closest fight Oura faces.

RingConn RingConn Gen 3
Bottom line. The best-value all-rounder - no fees, huge battery, swim-proof.
Pros
- No subscription - every feature included, even vascular insights
- Class-leading 10-14 day battery
- IP68 water resistance for swimming, plus silent vibration alarms
Cons
- Sleep-stage accuracy still trails Oura
- App is capable but less polished than Oura's
- Vascular and blood-pressure readings are trends, not clinical measurements
What's the real difference?
Four things separate them. Cost: the RingConn Gen 3 is £349 once with no fees; the Oura Ring 5 is £399 plus a mandatory £5.99/month membership, so RingConn is far cheaper to own. Battery: RingConn leads the whole category at 10-14 days versus Oura's 6-9. Water resistance: the RingConn Gen 3 carries an IP68 rating (dust-tight and protected for sustained immersion) suitable for swimming, and adds silent vibration alarms. Accuracy and app: Oura still leads - its sleep-stage tracking is more validated and its app more polished and coaching-led, while RingConn's vascular and blood-pressure readings are trend indicators rather than clinical measurements.
Is the RingConn Gen 3 good enough to skip Oura?
For most people, yes - if cost matters. The RingConn Gen 3 covers the essentials well, never charges a fee, lasts twice as long per charge and you can swim with it. Over three years it costs hundreds less than the Oura Ring 5 once membership is counted.
Skip it only if accuracy is your priority. Oura's sleep staging is still a step ahead, its app gives clearer, more actionable guidance, and its data history is deeper. If you want the most trustworthy numbers and the best daily coaching, that remains Oura's territory.
