RingConn Gen 2, World’s First Smart Ring with Sleep Apnea Monitoring, No APP Subscription, 12-Day Battery Life, Stress/Heart Rate/Women's Health Tracker, Android & iOS Compatible (Silver, Size 10)

First check the best fit of ring size using the size kit.Writing this review after 45 days, Looks elegant, works excellent, Battery Remains 10 days, Perfectly syncs with the phone. Don't feeling wearing it.App is too professional and provides loads of information on the Vitals, Sleep, Activity and Stress. Ai based plan needs a lot of improvement (still in beta), finding cumulative monthly achievements in the app is bit hard. Sometimes the info provided by app seems to be overwhelming.Sleep Apnea Tracking is good and looks suggestive. Only after couple of months it can be confirmed.Otherwise a best product that comes without any subscription and doing it's job so well.Kudoos to Ringconn Team.
