Product Details

COLMI R12 Smart Ring

COLMI R12 Smart Ring brings key fitness and activity information directly to your finger through an integrated touch display. Check the time, step count, heart-rate reading and battery level without opening your phone, then sync broader trends to the QRing app on compatible Android and iOS devices.

Why it stands out

Built-in display with tap and gesture control

Tracks heart rate, blood oxygen, sleep, steps, distance, calories and selected sports

Gesture controls for compatible phone functions, including remote photography

Wireless charging base with USB-C cable

Sizes 7–13 in black, gold and silver finishes

The COLMI R12 Smart Ring uses Bluetooth Low Energy and is designed for everyday fitness and wellness tracking. For better sensor contact, wear the ring snugly with the sensors positioned against the inside of your finger. Choose your size carefully using the supplied diameter and circumference chart.

The COLMI R12 Smart Ring is a general-wellness wearable, not a medical device. Measurements are estimates and should not be used to diagnose, treat or monitor a medical condition. Battery life, water resistance and feature availability can vary by size, settings, app version and usage.
