The COLMI R02 is a smart ring that combines advanced fitness features with a minimalist design. It tracks your heart rate, sleep quality and stages, and blood oxygen saturation (SpO2) 24/7. During activity, it automatically counts steps, calories, and distance to provide accurate data for a healthier lifestyle.
Choose from 21 sport modes (e.g., walking, running, cycling, yoga, dance, aerobics) and monitor progress in the QRing app. Thanks to IP68 water resistance, you don’t need to take it off for handwashing, rain, or swimming. Battery life up to 6 days and magnetic charging ensure worry-free use.
The elegant body made of polished stainless steel is complemented by an inner layer of hypoallergenic resin for comfortable wear. The ring weighs just 4.4 g, is 2.7 mm thick, and in this version is size 8 (diameter 18.1 mm, circumference 56.9 mm), so it’s barely noticeable on your hand.
