RingConn Gen 3 review

RingConn Gen 3 is the most complete no-subscription ring on this list for sleep. Overnight it records sleep duration, sleep stages, sleep apnea risk indicators and vascular load trends, and around the clock it tracks heart rate, HRV, blood oxygen, respiratory rate, skin temperature and stress. New for this generation are vibration alerts for health changes, sedentary reminders and low battery, plus vascular health trend insights, which RingConn is careful to describe as trends rather than single blood pressure readings. Its comparison table lists up to 14 days of battery, 10 days of offline storage, a 2.3mm titanium shell and sizes 6 to 15, with US pricing from $349. The universal charging case also charges other RingConn rings. Downsides are practical: Gen 3 sizing differs from earlier RingConn rings and standard ring sizes, and RingConn notes the ring is not a medical device, so apnea indicators are a prompt to see a doctor.

Who it is for

Sleepers who want breathing and apnea risk indicators plus long battery life without paying a monthly fee.
