Product information

Description

Colmi R02 smart ring in size 11 (20.6 mm diameter, 64.6 mm circumference) in black. This compact wearable provides continuous basic health and activity monitoring: heart rate, blood oxygen saturation (SpO2), sleep tracking, step count, distance and calories burned. The device supports 21 sports modes, has IP68 water resistance, a 17 mAh battery with up to 6 days of operation, and pairs with the QRing app via Bluetooth 5.0 for data synchronization and settings.

Advantages

The Colmi R02 ring combines a lightweight polished stainless steel exterior with a hypoallergenic resin interior, weighing only 4.4 g and measuring 2.7 mm in thickness for comfortable all-day wear. It offers continuous heart rate monitoring, SpO2 measurement, automatic sleep analysis and 21 exercise modes. The ring is IP68-rated for resistance to splashes and immersion, charges magnetically in about one hour and delivers up to six days of use on a single charge. Data and reports are available in the dedicated QRing app.

Suitable for

  • Daily activity tracking (steps, distance, calories)
  • Sleep monitoring and analysis
  • Basic health checks (heart rate and SpO2)
  • Sports and workouts across 21 modes (walking, running, cycling, yoga, etc.)
  • All-day discreet wear with water resistance for showering and swimming

How to use

Charge the ring using the supplied magnetic USB-A cable until fully charged (about 1 hour). Install the QRing app on a compatible smartphone and pair the ring via Bluetooth 5.0 to synchronize data and configure settings. Wear the ring on the finger that gives the most comfortable fit; the device will automatically monitor sleep and track activity when worn. Use the app to view heart rate, SpO2, sleep reports, activity details and to select sport modes.

Usage recommendations

For accurate readings, wear the ring snugly but comfortably on a stable finger position. Keep the ring and sensor area clean and dry when not measuring; follow the app’s guidance for sleep and sport mode selection. Although IP68 provides protection against splashes and immersion, avoid exposing the ring to high-temperature water (hot tubs/saunas) or strong chemicals. Charge regularly to maintain continuous monitoring.
