RingConn

RingConn Gen 2

The no-subscription smart ring — most of Oura's daily value for a one-off price, with less polish and a thinner evidence base.

Year one: $299; one-off
Hardware: $299; ~$279–299 one-off, no ongoing cost
Subscription: None; not required
Battery: 10–12 days

RingConn's pitch is simple: buy it once, own the data. It tracks sleep, HRV, resting heart rate, temperature and activity, with battery life that beats most rivals, and the Gen 2 case adds multi-week charging. The app is less refined than Oura's and the validation literature is thin — you're trusting the vendor's own numbers more than published comparisons. For trend-tracking rather than precision, that's an acceptable trade at the price.

Is the measurement validated?

Limited independent validation. Vendor-reported accuracy only; no substantial polysomnography literature. Fine for trends, not for answering a clinical question.

Best for

People who want ring-format sleep tracking without renting it.

Watch out

Thin validation and a less mature app. You're buying the business model as much as the sensor.
