Oura Ring 5 hub notes
- Smallest current Oura: 6.09 mm wide, 2.28 mm thick, 40% less volume than Ring 4 (Oura).
- Typically 6–9 days and ~80 minute charge despite the smaller shell.
- Same membership feature list as Ring 4 (sleep, 24/7 HR, Stress, Heart Health, Women's Health, SpO2). Health Radar / Counsel Health / GLP-1 Insights are described as Gen3-and-newer software, not Ring-5-only scores.
Ring 5 is the smallest current Oura: 6.09 × 2.28 mm titanium, sizes 6–13, typically 6–9 days, same membership software family as Ring 4. Buy it if you fit 6–13 and will pay membership. Skip it if you need sizes 4–5 or 14–15 (still a Ring 4 run) or you refuse a subscription.
RingConn Gen 3 hub notes
- No subscription on the OEM compare page.
- Battery: 10–12 days vibration on, 11–14 days vibration off; case charge about 120 minutes.
- Vascular health trends + sleep-apnea pattern (compare page: Yes on Gen 3 and Gen 2, not Gen 2 Air).
Gen 3 is the no-sub RingConn flagship: from $349, 2.3 mm, sizes 6–15, up to 14 days, sleep-apnea pattern plus vascular trends and haptic health alerts. Buy it if you want those extras without membership. Skip it if you want the thinner Gen 2, a jewelry-small Oura 5, or clinical BP/apnea diagnosis.

Frequently asked questions
Can I skip Oura Membership by buying RingConn instead?
RingConn’s compare page says no subscription fee. Oura’s cell: Oura Membership required for full app function. US $5.99/mo or $69.99/year; 1 complimentary month for new members. Account-tied, not ring-tied.. That is a software-access fork, not a medical claim.
