Colmi Smartring R12 20MM 10 (black) (R12 Black 10)

Smartring Colmi R12 20MM 10 (black)
Colmi R12 is a smart ring equipped with an LED screen, health monitoring sensors, and gesture control functions. It monitors heart rate, blood oxygen levels, sleep, and physical activity around the clock. It supports various sports modes and allows you to remotely control your smartphone. With 1ATM water resistance, you can wear it in the shower and while swimming, and the battery provides up to 5 days of operation or up to 15 days in standby mode. The included charging base will allow you to renew the device's power quickly and conveniently.

Easy-to-read display
The built-in LED screen located directly on the ring allows you to quickly view key information—without having to reach for your phone. You can check the current time, number of steps taken, battery level, and current heart rate. This is especially useful in situations where using a smartphone is inconvenient or impossible—such as when cycling or working out.

Health and activity monitoring 24/7
Colmi R12 is equipped with advanced biological sensors that analyze heart rate, blood oxygen levels (SpO₂), sleep, and stress levels around the clock. Heart rate is measured in real time, and the ring is capable of detecting even small changes, allowing a better understanding of the body's reactions in different situations. The quality of sleep is assessed based on its phases—light, deep, and awake—and the data is presented in the app in the form of clear graphs. This allows you to track your habits and take specific actions to improve your well-being and recovery.

Sport modes and exercise tracking
The ring supports several workout modes—including walking, running, cycling, or swimming. During activity, the Colmi R12 records heart rate, distance traveled, number of steps, exercise time, and the number of calories burned. This allows you to accurately track your progress and better plan your workouts. The data collected by the ring syncs with the app, giving you access to daily, weekly, and monthly statistics.

Simple gesture control and practical features
Colmi R12 also allows you to control your smartphone with gestures. With a simple movement of your hand, you can scroll the screen in apps such as TikTok, or remotely take a photo with your phone. This feature comes in handy when taking selfies or recording videos without touching the screen. In addition, the ring allows you to manually count repetitions, such as during prayer, affirmations, or exercise. Simply press a button on the case to record the next event—this data is also saved in the app.

Rugged design
The Colmi R12 has a water resistance rating of 1ATM, which means it can easily be used while washing hands, bathing, and even swimming in the sea or pool. In addition, the built-in rechargeable battery allows you to use the ring for about 5 days, depending on the intensity of use. In standby mode, the operating time extends up to 15 days. A charging base is included, which makes it easy to replenish energy quickly and conveniently without cables.
