More time on your finger, fewer charging breaks. Compare RingConn Gen 3’s claimed 11–14 days with vibration off or 10–12 days with it on, its 0.09–0.12 oz size-dependent weight, and its subscription-free app. Health reminders and vascular trends add context; they do not provide direct blood-pressure readings or an ECG.
