The verdict
Oura Ring 5 if you will pay that membership; Ultrahuman Ring PRO if you want the dated no-mandatory / ecosystem software sentence
Why: Subscription fork from OEM cells: Oura Ring 5 is membership; Ultrahuman Ring PRO is mixed. Quote the cells. Do not invent a software-quality winner. US PRO is still a dated pre-order (ships 10 Oct 2026) — not an in-stock wrist this week.

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.
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.

Frequently asked questions
Is Ultrahuman Ring PRO in US stock today?
The US buy page we re-opened still says shipping 10 October onwards. Treat it as pre-order, not a same-week retail SKU.
