The verdict
RingConn Gen 3 for new buyers on this RingConn line; RingConn Gen 2 if the leftover size, finish, or dated ticket is the fit
Why: Same brand (RingConn). RingConn Gen 3 ranks newer/current on this line. Cells are OEM quotes dated 2026-09-19 / 2026-09-19 — not a lab winner for comfort, accuracy, or real-world battery. Gen 3 ring-charge minutes were still blank on the FAQ block we re-opened; case FAQ still ~120 minutes. Do not invent ring minutes.

- No subscription (compare page).
Gen 2 is the thinner leftover RingConn: 2.0 mm / 2–3 g, 10–12 days, no sub, sleep-apnea monitoring, from $299 — but the page was out of stock on 2026-09-19. Buy it if you find stock and want the slimmer sleep-first ring. Skip it if you want Gen 3 vibration / vascular trends / size 15, or if checkout is empty.
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.
