The COLMI RING 2 combines the discreet design of a ring with a comprehensive set of features for monitoring health, sleep, and daily activity. Among other things, it allows you to monitor your heart rate, HRV, blood oxygen levels, stress, and body temperature, and the collected data can be analyzed using AI. With 5 ATM water resistance, you don’t have to take it off when swimming or washing your hands, and the long-lasting battery provides 3 to 5 days of use. Add to that its lightweight, compact design, which allows you to wear the ring comfortably both during the day and while you sleep at night.
Precise sensors allow the ring to collect a variety of health data. RING 2 lets you monitor your heart rate, HRV, blood oxygen levels, stress levels, and body temperature, providing convenient access to a wealth of information in the Q Ring app. This makes it easier for you to take care of your health and respond more quickly to any concerning changes. The collected data can also be used by built-in AI features for more detailed analysis. The system takes into account information regarding heart rate, blood oxygen levels, sleep, and activity, providing intelligent insights. This allows the numerous measurements collected by the ring to be used for more convenient tracking of your fitness and daily habits.
The COLMI RING 2 automatically monitors both nighttime sleep and daytime naps—there’s no need to manually start or stop recording. The device recognizes periods of wakefulness as well as light, deep, and REM sleep phases, and also records the time it takes to fall asleep, sleep efficiency, and nighttime awakenings.
The ring supports various sports modes, such as walking, running, cycling, and swimming. During workouts, it can track metrics such as heart rate, step count, distance traveled, calories burned, and workout duration. This allows you to conveniently track your progress and set new goals.
COLMI RING 2 also offers features designed to monitor menstrual health. These features help you predict your period and provide cycle-related information, helping you better track the changes taking place in your body. This data is available in the app along with your other health information.
The Friends and Family Ranking feature lets you use the Q Ring app to track and compare your step count with loved ones. With the ranking, you can check other users’ results and see where you stand. It’s extra motivation to stay active!
The app offers the “Space of Love” feature, which provides functions designed for couples. It allows you to record anniversaries and unlock successive relationship certificates, while the “Love Reminder” and “Walking in Sync” features provide additional opportunities for daily interaction. The ring can therefore be used not only to track health and activity but also to enjoy shared features with a loved one.
The COLMI RING 2 can also be used for touchless control of selected functions. A simple finger movement lets you control photos, videos, and games, and makes it easy to take photos without having to directly handle your phone. This is a convenient solution for people who frequently participate in video conferences, record vlogs, and more!
The RING 2 stands out for its lightweight and slim design, making it ideal for all-day wear or sleep tracking—it ensures long-lasting comfort. The ring is made of stainless steel, combining durability with an elegant design. Its 5 ATM water resistance rating means you can use it without worry even while washing your hands or swimming.
The high-capacity battery lets you use the ring for about 3–5 days. You won’t have to plug it in very often! The set also includes a handy charging case with a 200 mAh capacity and a USB-C port. You can use it to quickly and conveniently recharge the ring for continued use.
