The COLMI R12 blends minimalist design with smart features in a compact ring. The integrated LED display shows time, steps, heart rate, and battery status without pulling out your phone. Thanks to precise biometric sensors, you have a 24/7 overview of your health and activity, with data clearly presented in the QRing app.

The ring supports sports modes (walking, running, cycling, swimming), tracking distance, workout duration, and calories. With gesture control, you can scroll short videos, skip music tracks, or trigger the camera remotely. A handy manual counter feature (e.g., prayers, affirmations, workout reps) is saved to the app for easy review.

The 1ATM water-resistant build handles showers and swimming, while durable materials (stainless steel + epoxy resin) keep it lightweight and comfortable. The battery lasts 3–5 days depending on use, up to 15 days on standby, and recharges in about 1 hour using the included USB‑C charging base.

  • LED display on the ring: instant glance at time, steps, heart rate, and battery.
  • 24/7 health monitoring: heart rate, SpO₂, sleep, stress, HRV.
  • Sports and training: multiple modes, calories, distance, in‑app stats.
  • Gesture control: music, videos, e‑books, remote camera shutter.
  • 1ATM water resistance: carefree in the shower and while swimming.
  • Light and comfortable: just 4.7 g, durable stainless steel and epoxy.
