RingConn® Gen 3 redefines health tracking with a full-featured smart ring designed for seamless, everyday wear. It offers vascular trends monitoring to bring you better insight on health, an impressive 11 to 14 days of battery life with quick charging, and a vibration function to keep you stay on top of key moments. With the Gen 3 smart ring, you can have a complete and continuous view of your health with no subscription fees. Before you order, please note RingConn® ring sizes are different than those used in the US. For accuracy, size before you buy so you’ll know for sure - order the Gen 3 Ring Sizing Kit first, sold separately. Previous sizing kits for other models like Gen 1, Gen 2, and Gen 2 Air, will not work.
