It offers heart rate, HRV, SpO2, stress and body temperature measurement, automatic sleep monitoring, and insights in the Q Ring app including AI-powered analysis. Thanks to 5 ATM water resistance and a 3–5 day battery life, it is ideal for everyday wear day and night.
Health data and AI insights in the app
Track heart rate, HRV, blood oxygen (SpO2), stress and body temperature. The Q Ring app provides clear statistics and, thanks to artificial intelligence features, helps interpret the data better in the context of sleep and activity.
Automatic sleep monitoring 24/7
The ring automatically records night sleep and daytime naps without manual start. It distinguishes light, deep and REM phases, tracks time to fall asleep, sleep efficiency and nighttime awakenings – ideal for long-term improvement of recovery.
5 ATM water resistance and 3–5 day endurance
Thanks to 5 ATM water resistance, you don’t need to take the ring off when washing your hands or swimming. The 3–5 day battery life is complemented by a practical charging case (200 mAh) with USB‑C charging for convenient top-ups while traveling.
COLMI Ring 2 (size 10) is a smart ring designed for comfortable all-day wear and continuous tracking of key indicators.
