Side-by-Side Comparison
| Spec | RingConn Gen 3 (2026) | Amazfit Helio Ring (2024) |
|---|---|---|
| Price | $349.00 | $149.99 |
| Release Year | 2026 | 2024 |
| Battery Life (claimed) (days) | 14✓ | 4 |
| Battery, In Practice | RingConn's 'up to 14 days' assumes vibration alerts switched off; with alerts on the company itself quotes 10-12. The Gadgeteer measured 34% left after seven days of full use with alerts active, which extrapolates to about 10 days, not 14. Ring charges in ~90 minutes, case in ~120. | Amazfit publishes 'up to 4 days' — the shortest claim in this comparison, and it is the headline figure, so continuous SpO2 and temperature sensing pull it down from there. Wireless charging takes about 1 hour 40 minutes. |
| Subscription | None. RingConn states 'no subscription required' and every health feature, including the sleep-apnea assessment and Vascular Trends, is included with the ring. | None. Amazfit states no subscriptions are required, and Zepp Aura Premium (sleep sounds, detailed sleep reports, AI chat) is included free rather than sold separately. |
| 3-Year Cost of Ownership ($) | 349 | 149.99✓ |
| 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. | Three sizes only — 8 (24mm), 10 (25.7mm) and 12 (27.3mm). If your finger falls between them, there is no ring for you; every rival here offers seven to twelve sizes. |
| 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. | Not offered in the way rivals do it — with only three sizes Amazfit publishes inner diameters instead. That removes the kit wait but makes a poor fit far more likely. |
| 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. | Not published on Amazfit's US product page; the store's standard terms apply and should be checked before ordering. |
| 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. | PPG optical sensor for heart rate and blood oxygen, plus a genuine EDA (electrodermal activity) sensor for stress — one of the few rings here where 'stress' has a dedicated sensor behind it rather than being inferred from HRV alone. Readiness and sleep scores are still derived. |
| 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. General wellness product; the EDA sensor is not a cleared medical measurement. |
| Water Rating | IP68 / 10ATM / 100m / 328ft | 10ATM |
| Phone Support | iOS 17.0+ and Android 10.0+; The Gadgeteer found no platform-specific feature gaps | iOS and Android through the Zepp app |
| 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. | Wireless charging dock, and Amazfit's own US page states the USB-C cable is not included in the box — you supply your own. Export: not published by the manufacturer. |
| Warranty | 12 months | 12 months |
| Colors | Future Silver, Royal Gold, Matte Black, Brushed Silver ($369), Brushed Rose Gold ($369) | Titanium |
Category Scores
Subscription Freedom
The RingConn Gen 3 (2026) and Amazfit Helio Ring (2024) are level here, at 9.5/10 each. how much of the ring keeps working with no recurring payment — the category's defining trap is not what separates these two — look to the categories where the scores diverge.
Sleep Tracking
The RingConn Gen 3 (2026) leads clearly here, 8.5 against 7.0 — 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 Amazfit Helio Ring (2024) does not close the gap elsewhere.
Health Sensing
The RingConn Gen 3 (2026) leads clearly here, 8.0 against 6.5 — a 1.5-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 Amazfit Helio Ring (2024) does not close the gap elsewhere.
Battery Life
The RingConn Gen 3 (2026) leads clearly here, 9.0 against 4.5 — a 4.5-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 Amazfit Helio Ring (2024) does not close the gap elsewhere.
Sizing & Fit
The RingConn Gen 3 (2026) leads clearly here, 8.5 against 3.0 — a 5.5-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 Amazfit Helio Ring (2024) does not close the gap elsewhere.
App & Data
The RingConn Gen 3 (2026) leads clearly here, 7.5 against 7.0 — a 0.5-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 Amazfit Helio Ring (2024) 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 Amazfit Helio Ring (2024) does not close the gap elsewhere.
Value
The RingConn Gen 3 (2026) leads clearly here, 8.5 against 7.0 — a 1.5-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 Amazfit Helio Ring (2024) does not close the gap elsewhere.

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
Amazfit Helio Ring (2024)
Pros
- +$149.99 with no subscription — the cheapest ring here from a manufacturer with a real wearables business behind it
- +An actual EDA sensor for stress rather than an HRV-derived guess
- +10ATM water rating matches rings costing twice as much
- +Zepp Aura Premium is bundled, not upsold
Cons
- −Three sizes, full stop — 8, 10 and 12. This is the single biggest reason to buy something else
- −Four-day battery is the worst here by a wide margin; RingConn's cheapest ring does ten
- −Amazfit's own page says no USB-C cable is in the box
- −Data is most useful if you already own an Amazfit watch; standalone the Zepp app is thinner than Oura's
- −The Helio Ring 2 has been confirmed for the second half of 2026, so this is end-of-cycle hardware
