COLMI R02 Smart Ring size 11 (20.3 mm) is a lightweight wearable designed for continuous tracking of heart rate, SpO2, sleep, and daily activity across 21 sport modes. It connects via Bluetooth 5.0 to the QRing app for data syncing and long-term analysis. The titanium alloy construction with a hypoallergenic inner layer ensures comfort for all-day wear. With IP68 water resistance and 6–7 days of battery life plus a magnetic charging case, it supports reliable, uninterrupted health monitoring in daily use.
The ring automatically measures heart rate and blood oxygen saturation (SpO2), providing continuous background monitoring without manual activation. It also performs sleep tracking, identifying sleep stages such as light and deep sleep to evaluate overall rest quality and recovery patterns. In addition, it supports 21 sport modes, allowing structured tracking of different activities including walking, running, and general workouts, with metrics such as steps, distance, calories, and duration.
All collected data is stored locally and synchronized to the QRing mobile app via Bluetooth 5.0, where users can review trends and long-term changes. The titanium alloy exterior provides durability against daily wear, while the hypoallergenic inner lining improves comfort during extended use. Its slim, lightweight profile ensures it does not interfere with daily tasks or sleep.
With IP68 water resistance, the ring can be worn during washing, exercise, and exposure to water. Battery life ranges from 6 to 7 days per charge, and the included magnetic charging case allows convenient and fast recharging in approximately one hour. It is designed for users who want continuous health insights without wearing larger wearable devices.
