RingConn Gen 2 review

RingConn Gen 2 is the cheaper way to get apnea detection in a ring, and RingConn itself recommends it for people whose main focus is sleep and snoring risk. It measures time in REM, light and deep sleep, including naps, and detects breathing interruptions that may indicate sleep apnea. RingConn reports an OSAHS detection accuracy of 90.7% for its Sleep Breathing Insights algorithm, validated against a polysomnography reference dataset. During the day it tracks heart rate, blood oxygen, body temperature, steps and calories. The titanium ring is 6.8mm wide, 2mm thick and 2 to 3g, rated IP68 to 100m, and lasts up to 10 to 12 days depending on size, though RingConn warns the apnea feature can raise power use. US pricing starts at $299. What you give up against the Gen 3 is vibration alerts and vascular health insights, and the size-specific charging case cannot be replaced separately.

Who it is for

People whose main concern is sleep and snoring risk and who want apnea detection for less than the Gen 3.
