Smart Rings / Ultrahuman
Ultrahuman Ring PRO (2026)
15-day battery and no subscription — until you notice AFib is a paid add-on.
Overall score 7.8/10
Pros
- + 15-day claimed battery and 45 days with the case — nothing else here is close
- + 250 days of on-ring storage means it keeps working through a phone loss, a trip or a long stretch offline
- + ProRelease cutaway is the only answer any of these brands has to a swollen finger and a ring that cannot come off
- + Core sleep, recovery and stress data carries no recurring fee
Cons
- − AFib detection is a paid annual PowerPlug ($24-$39), so the 'no subscription' pitch does not cover the feature people most want
- − Ship dates keep moving — TechTimes said 20 June, gadgetsandwearables said 10 August, and Ultrahuman's own page now says 15 September onwards
- − Ultrahuman was banned from US import in October 2025 over Oura's patent; the Ring PRO is a redesign, and that history is a real supply risk
- − $479 as configured is the most expensive ring here, and the $399 version does not include the charging case
- − No FDA clearance is published for the AFib PowerPlug in the coverage of the US relaunch
Ultrahuman Ring PRO (2026) review: what the specs say
15-day battery and no subscription — until you notice AFib is a paid add-on. At $479, Ultrahuman's 2026 model sits at the premium end of the category — the smart Rings we compare run from $149.99 to $479. It scores 7.8/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Battery Life at 9.5/10 — real days between charges with continuous sensing on, plus what the charging case adds. The weakest is Value at 6.5/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: AFib detection is a paid annual PowerPlug ($24-$39), so the 'no subscription' pitch does not cover the feature people most want; and ship dates keep moving — TechTimes said 20 June, gadgetsandwearables said 10 August, and Ultrahuman's own page now says 15 September onwards. Every specification on this page comes from Ultrahuman's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| Battery Life (claimed) | 15 days |
| Battery, In Practice | Ultrahuman claims up to 15 days in standard mode, and 'up to 45 days' only when you count recharges held in the PRO charging case. Independent long-term battery testing under continuous SpO2 and temperature sensing was not available at the time of writing — the ring has only been shipping in the US for weeks. |
| Subscription | No subscription for your core data — sleep, recovery, movement, stress and circadian insights are included. But the clinical-sounding features are sold as optional annual PowerPlugs at $24-$39 each, and AFib detection is one of them. 'No subscription' and 'AFib included' are not the same sentence. |
| 3-Year Cost of Ownership | 479 $ |
| Sizes Offered | US 5-14, no half sizes. Ultrahuman states its sizes may differ slightly from standard US ring sizes. |
| Sizing Kit | Complimentary sizing kit with plastic sizers in sizes 5-14, shipped with the order. |
| Returns & Size Exchange | Not published on the pages reviewed. Check Ultrahuman's US terms at checkout before ordering a size. |
| Measured vs Inferred | PPG optical sensing plus skin temperature and motion, processed by an on-ring dual-core chip with on-chip machine learning. AFib detection, metabolic insight for GLP-1 users, ovulation tracking, snoring analysis and migraine insight are all software PowerPlugs layered on the same sensors — buying more PowerPlugs does not add hardware. |
| FDA Clearance | Not published by Ultrahuman for the Ring PRO or its AFib PowerPlug in the sources reviewed. Coverage of the US relaunch describes AFib detection as a paid PowerPlug and does not cite an FDA clearance. |
| Water Rating | 100m / 328ft |
| Phone Support | iOS and Android |
| Charger & Data Export | Standard charger and a 1m USB-C cable in the box; the PRO Charging Case is a $100 accessory (bundled into the $479 configuration). Export: not published by the manufacturer, though 250 days of history is retained on the ring itself. |
| Connectivity | Bluetooth Low Energy (version not published by Ultrahuman) |
| Material | Titanium unibody with PVD coating, epoxy and polycarbonate, with a ProRelease cutaway for emergency removal |
| Warranty | 12 months |
