Smart Rings / RingConn
RingConn Gen 2 (2024)
The cheapest way to get sleep-apnea screening on a finger with no monthly bill.
Overall score 8.4/10
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
RingConn Gen 2 (2024) review: what the specs say
The cheapest way to get sleep-apnea screening on a finger with no monthly bill. At $269, RingConn's 2024 model sits in the middle of the range — the smart Rings we compare run from $149.99 to $479. It scores 8.4/10 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 App & Data at 7.3/10, 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: the apnea figure is RingConn's own 90.7% accuracy claim, not an FDA-cleared diagnostic — it flags risk, it does not diagnose; and rose Gold is $359, $90 above the sale price of the other finishes. 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) | 12 days |
| Battery, In Practice | 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 | None. Sleep-apnea monitoring, continuous SpO2, cycle tracking and every other metric are included with the hardware. |
| 3-Year Cost of Ownership | 269 $ |
| Sizes Offered | US 6-14, no half sizes; RingConn sizing differs from standard US ring sizes |
| Sizing Kit | 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 | 14 days for returns and exchanges, in line with RingConn's other rings. |
| Measured vs Inferred | 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 | None published. Sleep-apnea monitoring is marketed as a wellness risk indicator; it is not an FDA-cleared apnea diagnostic. |
| Water Rating | IP68 (100m/328ft) |
| Phone Support | iOS 17.0+ and Android 10.0+ |
| Charger & Data Export | Magnetic charging case included, good for about 150 days of ring charges. Export: not published by the manufacturer. |
| Connectivity | Bluetooth 4.0+ |
| Material | Aerospace-grade titanium alloy with medical-grade epoxy resin; 2mm thick, 2-3g |
| Warranty | 12 months |
