Switch videos or music with a flick of the hand and take remote photos. A repeat counter is included for prayers, affirmations, or workouts.
The COLMI R12 is a subtle, lightweight, and durable smart ring that combines a fitness tracker, notification assistance, and practical phone control. The built-in LED display right on the ring shows time, steps, heart rate, and battery status—no need to reach for your phone. Thanks to 1ATM water resistance, you can use it confidently while washing hands, in the shower, and even while swimming.
Advanced biosensors continuously measure heart rate, blood oxygen level (SpO₂), HRV, stress, and analyze sleep stages. In the QRing app, you get clear statistics and long-term trends to better plan training and recovery. It includes sports modes (walking, running, cycling, swimming) and records distance, workout time, calories, and steps.
Gesture control lets you easily switch short videos or music and take photos remotely. The practical repeat counter (tasbih, affirmations, exercise sets) is recorded in the app. Fast charging is provided by a magnetic charging dock with a USB‑C cable; battery life is 3–5 days depending on use and up to 15 days on standby.
