Side-by-Side Comparison
| Spec | Ultrahuman Ring PRO (2026) | RingConn Gen 2 (2024) |
|---|---|---|
| Price | $479.00 | $269.00 |
| Release Year | 2026 | 2024 |
| Battery Life (claimed) (days) | 15✓ | 12 |
| 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. | RingConn publishes 10-12 days for the ring and 150 days including the case. There is no vibration motor to switch off, so the figure is less conditional than the Gen 3's. Ring charges in about 90 minutes. |
| 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-$39 each, and AFib detection is one of them. 'No subscription' and 'AFib included' are not the same sentence. | None. Sleep-apnea monitoring, continuous SpO2, cycle tracking and every other metric are included with the hardware. |
| 3-Year Cost of Ownership ($) | 479 | 269✓ |
| Sizes Offered | US 5-14, no half sizes. Ultrahuman states its sizes may differ slightly from standard US ring sizes. | US 6-14, no half sizes; RingConn sizing differs from standard US ring sizes |
| Sizing Kit | Complimentary sizing kit with plastic sizers in sizes 5-14, shipped with the order. | Free sizing kit selectable at checkout, shipped ahead of the ring; the kit round trip adds one to two weeks before the ring is dispatched. |
| Returns & Size Exchange | Not published on the pages reviewed. Check Ultrahuman's US terms at checkout before ordering a size. | 14 days for returns and exchanges, in line with RingConn's other rings. |
| 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. | Optical heart-rate sensor, skin-temperature sensor and accelerometer. Heart rate, SpO2 and temperature are tracked continuously rather than spot-sampled. The sleep-apnea figure RingConn quotes (90.7% accuracy) is a risk indicator derived from those signals, not a clinical sleep study. |
| 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 published. Sleep-apnea monitoring is marketed as a wellness risk indicator; it is not an FDA-cleared apnea diagnostic. |
| Water Rating | 100m / 328ft | IP68 (100m/328ft) |
| Phone Support | iOS and Android | iOS 17.0+ and Android 10.0+ |
| 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. | Magnetic charging case included, good for about 150 days of ring charges. Export: not published by the manufacturer. |
| Warranty | 12 months | 12 months |
| Colors | Bionic Gold, Space Silver, Aster Black, Raw Titanium | Royal Gold, Future Silver, Matte Black, Rose Gold ($359) |
Category Scores
Subscription Freedom
The RingConn Gen 2 (2024) leads clearly here, 9.5 against 7.0 — a 2.5-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 Ultrahuman Ring PRO (2026) does not close the gap elsewhere.
Sleep Tracking
The RingConn Gen 2 (2024) is marginally ahead, 8.3 to 8.0. A gap this small rarely decides a purchase on its own, though it counts if sleep staging depth, overnight accuracy and how usable the morning report is is your priority.
Health Sensing
The Ultrahuman Ring PRO (2026) leads clearly here, 8.3 against 7.8 — a 0.5-point margin on what the sensors genuinely measure — heart rate, SpO2, temperature, ECG — rather than infer. If that is what you are buying for, the RingConn Gen 2 (2024) does not close the gap elsewhere.
Battery Life
The Ultrahuman Ring PRO (2026) leads clearly here, 9.5 against 8.7 — a 0.8-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 RingConn Gen 2 (2024) does not close the gap elsewhere.
Sizing & Fit
The RingConn Gen 2 (2024) leads clearly here, 8.5 against 8.0 — a 0.5-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 Ultrahuman Ring PRO (2026) does not close the gap elsewhere.
App & Data
The Ultrahuman Ring PRO (2026) is marginally ahead, 7.5 to 7.3. A gap this small rarely decides a purchase on its own, though it counts if app stability, insight depth, platform parity and whether you can get your history out is your priority.
Durability
The RingConn Gen 2 (2024) 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 RingConn Gen 2 (2024) leads clearly here, 8.7 against 6.5 — a 2.2-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 Ultrahuman Ring PRO (2026) does not close the gap elsewhere.

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
RingConn Gen 2 (2024)
Pros
- +Sleep-apnea monitoring included with no subscription — the Gen 2 Air drops this feature entirely
- +$269 on sale from $299, and three-year cost is that same $269
- +2mm thick and 2-3g, thinner and lighter than any Oura
- +150-day charging case means one wall charge a season
Cons
- −The apnea figure is RingConn's own 90.7% accuracy claim, not an FDA-cleared diagnostic — it flags risk, it does not diagnose
- −Rose Gold is $359, $90 above the sale price of the other finishes
- −Bluetooth 4.0-class radio and a 2024 sensor stack; the Gen 3 adds vibration alerts and vascular trending
- −14-day return window, and RingConn sizes do not map to standard US ring sizes
- −No published data-export route, so your history lives in RingConn's app
