Smart Rings / RingConn
RingConn Gen 2 Air (2025)
$199 once, ten-day battery, no monthly bill — the apnea engine is what you gave up.
Overall score 8.1/10
Pros
- + $199 all-in, and $199 is still the three-year cost — a base Oura Ring 5 is $608.97 over the same period
- + Ten-day battery in a 2mm, 2.5-4g band that does not look like a wearable
- + Same IP68 / 100m rating as RingConn's flagship
- + RingConn's Oura settlement means the US supply is licensed, not provisional
Cons
- − Sleep-apnea monitoring is removed — that is the specific feature the $269 Gen 2 keeps, and the reason for the price gap
- − Dock charger instead of a charging case, so no reserve charges when travelling
- − Only two finishes, both light-coloured, and no matte black
- − 14-day return window in a category where the number one complaint is fit
- − No published data export
RingConn Gen 2 Air (2025) review: what the specs say
$199 once, ten-day battery, no monthly bill — the apnea engine is what you gave up. At $199, RingConn's 2025 model sits among the cheapest we cover — the smart Rings we compare run from $149.99 to $479. It scores 8.1/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Subscription Freedom at 9.5/10 — how much of the ring keeps working with no recurring payment — the category's defining trap. The weakest is Health Sensing at 6.8/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: sleep-apnea monitoring is removed — that is the specific feature the $269 Gen 2 keeps, and the reason for the price gap; and dock charger instead of a charging case, so no reserve charges when travelling. Every specification on this page comes from RingConn's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.

Full Specifications
| Battery Life (claimed) | 10 days |
| Battery, In Practice | RingConn publishes 'up to 10 days'. There is no vibration motor and no apnea engine running overnight, which is part of why it holds up. Full charge takes about 90 minutes; the ring stores 5-7 days of data offline if you do not open the app. |
| Subscription | None. Everything the ring measures is free — but note that what it measures is a shorter list than the Gen 2, because sleep-apnea monitoring is removed. |
| 3-Year Cost of Ownership | 199 $ |
| Sizes Offered | US 6-14, no half sizes; RingConn sizing differs from standard US ring sizes |
| Sizing Kit | Free sizing kit selectable at checkout and shipped before the ring, adding one to two weeks to the order. |
| Returns & Size Exchange | 14 days for returns and exchanges. |
| Measured vs Inferred | Optical heart-rate sensor, skin-temperature sensor and accelerometer. Heart rate, SpO2, HRV, respiratory rate and skin temperature are tracked; stress is a derived score. Sleep-apnea monitoring, which the full Gen 2 has, is absent from this model. |
| FDA Clearance | None published. General wellness product. |
| Water Rating | IP68 (100m/328ft) |
| Phone Support | iOS 17.0+ and Android 10.0+ |
| Charger & Data Export | Magnetic charging dock rather than the Gen 2's case — the biggest thing you give up alongside apnea monitoring, because there is no pocketable reserve of charges. Export: not published by the manufacturer. |
| Connectivity | Bluetooth 5.0 |
| Material | Titanium steels with PVD coating and medical-grade epoxy resin; 2mm thick, 2.5-4g |
| Warranty | 12 months |
