The COLMI R02 combines a stylish ring with a smart fitness tracker. Thanks to precise sensors, it tracks heart rate 24/7, blood oxygen saturation (SpO2), and provides an in-depth evaluation of sleep quality including individual stages. All data is clearly available in the QRing app for better recovery and training planning.
During activity, the ring accurately counts steps, distance, and calories burned, and offers up to 21 sports modes—from walking and running, through cycling and yoga, to dance or aerobics. The IP68-rated design shrugs off rain and showers, and magnetic charging replenishes the battery in approximately 1 hour. Polished stainless steel on the outside and hypoallergenic resin on the inside ensure all-day wearing comfort.
