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.
Ultrahuman Ring PRO hub notes
- Up to 15 days (Turbo ~12 / Chill 15+); case up to 45 days extra.
- Up to 250 days on-ring storage; case up to 1 year of ring data (Chill Mode footnote).
- No recurring fee for core data (US buy FAQ, 2026-09-19).
PRO is the long-battery, no-mandatory-sub Ultrahuman: $479, up to 15 days, 250-day storage, PRO case. In the US it is a pre-order shipping from 10 October 2026 — the February blog excluded the United States. Buy it if you will wait and want continuity. Skip it if you need a ring on a finger this week, or if AIR’s lighter 4–6 day leftover is enough.
