Side-by-Side Comparison
| Spec | Ultrahuman Ring PRO (2026) | Samsung Galaxy Ring (2024) |
|---|---|---|
| Price | $479.00 | $299.99 |
| Release Year | 2026 | 2024 |
| Battery Life (claimed) (days) | 15✓ | 7 |
| 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. | Samsung claims a seven-day charge but notes in the same breath that the smallest sizes reach only about six days. The 'up to 14 days' headline is the ring plus a full charge held in the cradle, not fourteen days of wear. |
| 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-$39 each, and AFib detection is one of them. 'No subscription' and 'AFib included' are not the same sentence. | None. Samsung Health is free and every Galaxy Ring metric is included with the hardware — this is the whole argument against Oura. |
| 3-Year Cost of Ownership ($) | 479 | 299.99✓ |
| Sizes Offered | US 5-14, no half sizes. Ultrahuman states its sizes may differ slightly from standard US ring sizes. | US 5-13, nine sizes, no half sizes |
| Sizing Kit | Complimentary sizing kit with plastic sizers in sizes 5-14, shipped with the order. | Free sizing kit; Samsung tells you to wear the sample ring for 24 hours or more before confirming the size, which front-loads several days onto the order. |
| Returns & Size Exchange | Not published on the pages reviewed. Check Ultrahuman's US terms at checkout before ordering a size. | Not published on Samsung's Galaxy Ring product page; Samsung.com's standard consumer return terms apply and should be checked at checkout. |
| 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. | Accelerometer, PPG optical sensor and a skin-temperature sensor. Heart rate and blood oxygen are PPG-derived; Energy Score, Sleep Score and stress are Samsung Health composites calculated from those three inputs, not separate measurements. |
| 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. | None for the ring. Samsung's FDA-cleared ECG and blood-pressure features live on the Galaxy Watch, which has electrodes; the ring has none and cannot do either. |
| Water Rating | 100m / 328ft | 10ATM (100m for up to 10 minutes) plus IP68 (6ft for 30 minutes) |
| Phone Support | iOS and Android | Android only. There is no iOS app at all — an iPhone owner cannot use this ring, and full functionality assumes a compatible Samsung Galaxy phone with a Samsung account. |
| 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. | Proprietary transparent charging cradle with USB-C, included. Export: Samsung Health writes to Android Health Connect and offers a personal-data download through the Samsung account, so history is not locked to the ring. |
| Warranty | 12 months | 12 months |
| Colors | Bionic Gold, Space Silver, Aster Black, Raw Titanium | Titanium Black, Titanium Silver, Titanium Gold |

Pros & Cons
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
Samsung Galaxy Ring (2024)
Pros
- +Zero subscription — three years costs $299.99 against $608.97 for a base Oura Ring 5
- +Now routinely $299.99 against a $399.99 list price
- +The charging cradle is the best-designed in the category and adds a genuine second week away from mains power
- +10ATM plus IP68, and a concave outer profile that keeps knocks off the widest point of the ring
Cons
- −Android only — no iOS app exists, so an iPhone is an outright disqualification, not a degraded experience
- −Several features (gesture control, auto workout hand-off) assume a Samsung Galaxy phone specifically, not just any Android
- −No ECG and no blood pressure: Samsung's FDA-cleared versions of both are Galaxy Watch features and cannot be added here
- −Health insight depth is behind Oura's — the scores are simpler and there is less to interrogate
- −Two years on from launch with the successor reportedly pushed to early 2027, so this is late-cycle hardware
