The RingConn(R) Gen 2 redefines health tracking. It is a full-featured smart ring designed for seamless, everyday wear. The digital ring offers automatic sleep apnea monitoring to help you optimize rest and an ultra-slim, lightweight build that merges comfort with style. You also get an impressive 10 to 12 days of battery life (up to 150 days with its portable charging case), quick charging, and with our RingConn(R) EcoPower technology, we've refined optical pathways and enhanced algorithms to achieve reduced power consumption while maintaining familiar performance levels. Best of all, you'll get comprehensive monitoring with no subscription fees. Please note - before you order, be sure to review the Sizing Guide, as seen in the images section, as RingConn(R) ring sizes are different than those used in the US. Or better yet, size before you buy so you'll know for sure - order the Gen 2 Ring Sizing Kit first, sold separately.
