Side-by-Side Comparison
| Spec | Oura Ring 4 (2024) | RingConn Gen 3 (2026) |
|---|---|---|
| Price | $249.00 | $349.00 |
| Release Year | 2024 | 2026 |
| Battery Life (claimed) (days) | 8 | 14✓ |
| Battery, In Practice | Oura publishes 5-8 days and states outright that it varies with ring size, app settings and activity level. Smaller sizes are nearer 5. Charging takes 20-80 minutes depending on how flat it is. | RingConn's 'up to 14 days' assumes vibration alerts switched off; with alerts on the company itself quotes 10-12. The Gadgeteer measured 34% left after seven days of full use with alerts active, which extrapolates to about 10 days, not 14. Ring charges in ~90 minutes, case in ~120. |
| Subscription | Required in practice. $5.99/month or $69.99/year after one free month, on exactly the same terms as the Ring 5 — the membership is per account, not per ring, so upgrading later does not cost a second subscription. | None. RingConn states 'no subscription required' and every health feature, including the sleep-apnea assessment and Vascular Trends, is included with the ring. |
| 3-Year Cost of Ownership ($) | 458.97 | 349✓ |
| Sizes Offered | US 4-15, no half sizes — the broadest range here, and the reason to buy the older generation if your finger is very small or very large | US 6-15, no half sizes. RingConn warns its sizing differs slightly from standard US ring sizes and from other smart-ring brands, so an Oura size does not transfer. |
| Sizing Kit | Free plastic sizing kit ships before the ring; wear the sizer at least 24 hours including overnight. Budget about a week before the real ring is ordered. | Free sizing kit selectable at checkout; it arrives in 3-8 days and the ring only ships after you confirm a size, so the kit adds one to two weeks to delivery. |
| Returns & Size Exchange | Oura does not publish a return window on its warranty page. The 1-year limited warranty excludes scratches, dents and batteries, and secondhand purchases from unauthorised resellers are not covered at all. | 14 days for returns and exchanges — the shortest window of any brand here, and it starts before most people have finished testing the fit. |
| Measured vs Inferred | Green plus infrared LEDs for continuous heart rate and HRV, red plus infrared for blood oxygen reported overnight rather than continuously, an NTC skin-temperature sensor and an accelerometer. Readiness, Stress and Resilience are derived scores on top of those signals. | Optical heart-rate sensor, temperature sensor, 3-axis accelerometer and a vibration motor. Heart rate, SpO2, HRV, respiratory rate, skin temperature and stress are tracked continuously against a personal baseline. Vascular Trends is the trap: it needs an external cuff reading first to calibrate and then reports trends, so it is not a standalone blood-pressure measurement. |
| FDA Clearance | None published. Oura markets the ring and app as general wellness, not as a medical device. | None published. The sleep-apnea assessment is a risk indicator, not a diagnosis, and Vascular Trends is explicitly a trend against a cuff baseline you supply. |
| Water Rating | Water resistant to 100m/328ft | IP68 / 10ATM / 100m / 328ft |
| Phone Support | iOS and Android, full feature parity | iOS 17.0+ and Android 10.0+; The Gadgeteer found no platform-specific feature gaps |
| Charger & Data Export | Proprietary size-specific dock plus USB-C cable in the box; the Ring 5 charger is a different part. Export: not published as a one-click history download; Oura documents a personal-access-token Cloud API. | Universal wireless charging case — unlike Oura's, one case fits every ring size, and RingConn quotes 150+ days of untethered use from it. Export: not published by the manufacturer. |
| Warranty | 12 months | 12 months |
| Colors | Silver, Black, Brushed Silver, Stealth, Gold, Rose Gold | Future Silver, Royal Gold, Matte Black, Brushed Silver ($369), Brushed Rose Gold ($369) |
Category Scores
Subscription Freedom
The RingConn Gen 3 (2026) leads clearly here, 9.5 against 2.0 — a 7.5-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 Oura Ring 4 (2024) does not close the gap elsewhere.
Sleep Tracking
The Oura Ring 4 (2024) leads clearly here, 9.3 against 8.5 — a 0.8-point margin on sleep staging depth, overnight accuracy and how usable the morning report is. If that is what you are buying for, the RingConn Gen 3 (2026) does not close the gap elsewhere.
Health Sensing
The Oura Ring 4 (2024) is marginally ahead, 8.2 to 8.0. 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 RingConn Gen 3 (2026) leads clearly here, 9.0 against 7.0 — 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 4 (2024) does not close the gap elsewhere.
Sizing & Fit
The Oura Ring 4 (2024) and RingConn Gen 3 (2026) are level here, at 8.5/10 each. how many sizes exist, how good the sizing kit is, and how forgiving the exchange policy is is not what separates these two — look to the categories where the scores diverge.
App & Data
The Oura Ring 4 (2024) 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 RingConn Gen 3 (2026) does not close the gap elsewhere.
Durability
The RingConn Gen 3 (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 Oura Ring 4 (2024) does not close the gap elsewhere.
Value
The RingConn Gen 3 (2026) leads clearly here, 8.5 against 7.5 — a 1.0-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 4 (2024) does not close the gap elsewhere.

Pros & Cons
Oura Ring 4 (2024)
Pros
- +Sizes 4 to 15 — if the Ring 5's 6-13 window excludes you, this is the Oura that fits
- +Now routinely $249 in silver or black, $100 under its own list price, for sensing that is a generation behind at most
- +Recessed sensors mean no protruding domes pressing into the finger, unlike the Circular Ring 2
- +Same app, same membership, same iOS/Android parity as the Ring 5
Cons
- −The $5.99/month membership still applies, so three years costs $458.97 even at the discounted hardware price
- −Noticeably chunkier than the Ring 5 — that is the whole reason the Ring 5 exists
- −Discounted stock is concentrated in Silver and Black; Gold and Rose Gold still list at $499
- −Warranty covers manufacturing defects only, not the scratches titanium picks up in normal wear
- −Amazon listings are per size and per colour, so the ASIN you click must match the size you actually need
RingConn Gen 3 (2026)
Pros
- +No subscription at all: $349 once, against $608.97 over three years for a base Oura Ring 5
- +A vibration motor means silent alarms and alerts — no other ring in this comparison at this price has one
- +The charging case is size-universal and good for 150+ days, so travel needs no cable
- +RingConn settled with Oura and holds a multi-year patent licence, so US supply is not at risk the way Ultrahuman's was
Cons
- −Vascular Trends is not blood-pressure measurement — you must supply a cuff reading to calibrate it, a requirement reviewers found buried in the fine print
- −The 14-day battery figure only holds with vibration alerts off; ten days is the realistic number with them on
- −14-day return and exchange window is the tightest here, which is punishing in a category where sizing is the main complaint
- −RingConn sizing deliberately differs from standard US ring sizes, so you cannot skip the sizing kit
- −Premium brushed finishes cost $369, and the app leaves several of its own metrics undefined
