Side-by-Side Comparison
| Spec | RingConn Gen 3 (2026) | Oura Ring 5 (2026) |
|---|---|---|
| Price | $349.00 | $399.00 |
| Release Year | 2026 | 2026 |
| Battery Life (claimed) (days) | 14✓ | 9 |
| Battery, In Practice | 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. | 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. |
| Subscription | None. RingConn states 'no subscription required' and every health feature, including the sleep-apnea assessment and Vascular Trends, is included with the ring. | Required in practice. $5.99/month or $69.99/year after one free month. Oura's own FAQ: without a membership 'your Oura Ring and Oura App will still function, but the insights, personal health data, and benefits you receive will be much more limited' — you keep the three headline scores and lose the 50+ metrics behind them. |
| 3-Year Cost of Ownership ($) | 349✓ | 608.97 |
| Sizes Offered | 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. | 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. |
| Sizing Kit | 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. | 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. |
| Returns & Size Exchange | 14 days for returns and exchanges — the shortest window of any brand here, and it starts before most people have finished testing the fit. | 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. |
| Measured vs Inferred | 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. | 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. |
| FDA Clearance | 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. | 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. |
| Water Rating | IP68 / 10ATM / 100m / 328ft | IP68 and water resistant to 100m/328ft; Oura says it is not for scuba diving |
| Phone Support | iOS 17.0+ and Android 10.0+; The Gadgeteer found no platform-specific feature gaps | iOS and Android, full feature parity |
| Charger & Data Export | 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. | 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. |
| Warranty | 12 months | 12 months |
| Colors | Future Silver, Royal Gold, Matte Black, Brushed Silver ($369), Brushed Rose Gold ($369) | Silver, Black, Brushed Silver ($499), Stealth ($499), Gold ($499), Deep Rose ($499) |

Pros & Cons
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
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
