Side-by-Side Comparison
| Spec | Oura Ring 5 (2026) | Ultrahuman Ring PRO (2026) |
|---|---|---|
| Price | $399.00 | $479.00 |
| Release Year | 2026 | 2026 |
| Battery Life (claimed) (days) | 9 | 15✓ |
| Battery, In Practice | Oura's own claim is a range, 'up to 6-9 days depending on ring size and usage' — the small sizes sit at the bottom of it because the battery is physically smaller. TechCrunch's reviewer was at roughly 25% after five days of continuous wear. Charging takes about 80 minutes. | 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 | Required in practice. $5.99/month or $69.99/year after one free month. Oura's own FAQ: without a membership 'your Oura Ring and Oura App will still function, but the insights, personal health data, and benefits you receive will be much more limited' — you keep the three headline scores and lose the 50+ metrics behind them. | 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-$39 each, and AFib detection is one of them. 'No subscription' and 'AFib included' are not the same sentence. |
| 3-Year Cost of Ownership ($) | 608.97 | 479✓ |
| Sizes Offered | US 6-13, no half sizes. Ring 4 covered 4-15; Oura told TechCrunch the smaller form factor is harder to manufacture at the extremes, so small and large fingers lose the option entirely. | US 5-14, no half sizes. Ultrahuman states its sizes may differ slightly from standard US ring sizes. |
| Sizing Kit | Free plastic sizing kit ships before the ring. Oura instructs you to wear the sizer for at least 24 hours including overnight, so the kit round trip adds roughly a week before the ring is even ordered. | Complimentary sizing kit with plastic sizers in sizes 5-14, shipped with the order. |
| Returns & Size Exchange | Oura does not publish a return window on its warranty page. The 1-year limited warranty explicitly excludes 'normal wear and tear, such as scratches and dents caused by everyday handling' and lists batteries as a non-covered consumable part. | Not published on the pages reviewed. Check Ultrahuman's US terms at checkout before ordering a size. |
| Measured vs Inferred | Green and infrared LEDs for continuous heart rate and HRV; red and infrared LEDs for blood oxygen, which Oura reports as an overnight figure rather than an all-day continuous trace; NTC skin-temperature sensor; accelerometer. Readiness, Stress, Resilience and Health Radar are derived scores computed from those four signals, not separate measurements. | 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 | None published for the Ring 5 or its app features — Oura markets the whole product as general wellness. The Blood Pressure Signals feature announced alongside the Ring 5 is not a cuff-equivalent blood-pressure measurement. | 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 | IP68 and water resistant to 100m/328ft; Oura says it is not for scuba diving | 100m / 328ft |
| Phone Support | iOS and Android, full feature parity | iOS and Android |
| Charger & Data Export | Proprietary size-specific dock in the box plus a USB-C cable — a charger made for one ring size does not fit another, so a replacement has to match your ring. Export: not published as a one-click history download; Oura documents a personal-access-token Cloud API that third-party tools use to pull history. | 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. |
| Warranty | 12 months | 12 months |
| Colors | Silver, Black, Brushed Silver ($499), Stealth ($499), Gold ($499), Deep Rose ($499) | Bionic Gold, Space Silver, Aster Black, Raw Titanium |
Category Scores
Subscription Freedom
The Ultrahuman Ring PRO (2026) leads clearly here, 7.0 against 2.0 — a 5.0-point margin on how much of the ring keeps working with no recurring payment — the category's defining trap. If that is what you are buying for, the Oura Ring 5 (2026) does not close the gap elsewhere.
Sleep Tracking
The Oura Ring 5 (2026) leads clearly here, 9.5 against 8.0 — a 1.5-point margin on sleep staging depth, overnight accuracy and how usable the morning report is. If that is what you are buying for, the Ultrahuman Ring PRO (2026) does not close the gap elsewhere.
Health Sensing
The Oura Ring 5 (2026) is marginally ahead, 8.5 to 8.3. A gap this small rarely decides a purchase on its own, though it counts if what the sensors genuinely measure — heart rate, SpO2, temperature, ECG — rather than infer is your priority.
Battery Life
The Ultrahuman Ring PRO (2026) leads clearly here, 9.5 against 7.5 — a 2.0-point margin on real days between charges with continuous sensing on, plus what the charging case adds. If that is what you are buying for, the Oura Ring 5 (2026) does not close the gap elsewhere.
Sizing & Fit
The Ultrahuman Ring PRO (2026) leads clearly here, 8.0 against 6.5 — a 1.5-point margin on how many sizes exist, how good the sizing kit is, and how forgiving the exchange policy is. If that is what you are buying for, the Oura Ring 5 (2026) does not close the gap elsewhere.
App & Data
The Oura Ring 5 (2026) leads clearly here, 9.0 against 7.5 — a 1.5-point margin on app stability, insight depth, platform parity and whether you can get your history out. If that is what you are buying for, the Ultrahuman Ring PRO (2026) does not close the gap elsewhere.
Durability
The Oura Ring 5 (2026) leads clearly here, 8.0 against 7.5 — a 0.5-point margin on finish scratch resistance, water rating in practice, and whether the finish is warrantied. If that is what you are buying for, the Ultrahuman Ring PRO (2026) does not close the gap elsewhere.
Value
The Ultrahuman Ring PRO (2026) leads clearly here, 6.5 against 6.0 — a 0.5-point margin on what the ring delivers against its total cost of ownership, not just its sticker price. If that is what you are buying for, the Oura Ring 5 (2026) does not close the gap elsewhere.

Pros & Cons
Oura Ring 5 (2026)
Pros
- +Genuinely the smallest ring here — 40% smaller than Ring 4 and the first Oura that does not read as a gadget on the hand
- +Sleep staging remains the reference the rest of the category is measured against
- +iOS and Android get identical features, which Samsung cannot say
- +100m water rating and a new PVD coating Oura claims is more scratch resistant than Ring 4's
Cons
- −$5.99/month forever: the real three-year price of the base finish is $608.97, more than triple a RingConn Gen 2 Air
- −Sizes 6-13 only — Ring 4 went 4 to 15, so this generation silently dropped the smallest and largest fingers
- −The premium finishes are a $100 tax for the same electronics: Stealth, Brushed Silver, Gold and Deep Rose are all $499
- −Warranty explicitly excludes scratches and dents, and the battery is listed as a non-covered consumable
- −The charger is keyed to your ring size, so it is not a part you can borrow or generically replace
Ultrahuman Ring PRO (2026)
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
