Smartring COLMI R02 size 12 21.3mm (black) + charging case

Smartring COLMI R02 size 12

The COLMI R02 Smart Ring, size 12 (21.3 mm), black, is a lightweight and discreet smart ring that combines health monitoring with sports features. The device measures your heart rate, blood oxygen saturation (SpO2), analyzes your sleep, and records your daily activity and workouts in 21 sport modes. Thanks to Bluetooth 5.0, it works with the QRing app, saving data for later synchronization, while IP68 waterproofing and the included charging case ensure convenient use for up to 6-7 days on a single charge.

Compact shape and comfortable to wear

The ring was designed for maximum comfort during everyday use. Its low weight of 4.7g and thickness of just 2.7mm means you'll quickly forget you're wearing it. It doesn't restrict your hand movements and doesn't get in the way while typing, working out, or exercising. This means you can wear it continuously all day and night without having to take it off. This, in turn, allows for continuous data collection, even in moments often missed with larger devices.

Monitoring health and body parameters

COLMI R02 constantly monitors basic body parameters, such as heart rate and blood oxygen saturation (SpO2). Measurements take place automatically in the background, meaning you don't have to manually activate each function. This makes it easier to notice changes in your body based on activity, stress, or rest. Data is saved in the device's memory, so even if you don't have your phone with you, nothing will be lost. After syncing with the app, you can analyze the results in a broader context and observe long-term changes.

Sleep and Recovery Analysis

One of the ring's strengths is sleep monitoring, which works automatically every night. The device recognizes sleep stages, such as light and deep sleep, and records total rest time. This allows you to see not only how much sleep you're getting, but also how effectively your body is regenerating. Data is saved locally and synced with the app in the morning, giving you a complete picture of your sleep without the need for a constant connection. This feature will be especially appreciated by those who don't like to sleep with their watch on.

Sports and Activity Modes

The ring offers 21 sports modes that cover the most popular forms of exercise. Whether you choose walking, running, or general training, the device records key activity data. This includes steps, distance, calories burned, and duration. This allows you to better control your training intensity and gradually increase your activity. Regularly recording your data also makes it easy to see progress and stay motivated.

Connectivity and Compatibility

Bluetooth 5.0 is responsible for communication, ensuring a stable connection and low power consumption. After pairing with the QRing app, all data is stored in one place, where it is presented in a clear form. Synchronization is quick and requires no complicated configuration. The ring is compatible with Android 4.4 and newer, iOS 8.0 and newer, and Harmony OS, making it easy to connect to both older and newer smartphones.

Charging Case and Battery Life

The included case doubles as a practical docking station, making it easy to both store and charge the ring. Simply place it in the appropriate spot to begin charging via the magnetic contacts. The ring itself offers a battery life of 6-7 days, allowing you to use it without frequent charger recharging. A full charge takes about an hour, so even a short break is enough to restore full functionality. This solution is well-suited for everyday use, where simplicity and speed are key.

Durability and materials

The titanium alloy casing increases resistance to scratches and everyday wear. This allows the ring to better withstand contact with hard surfaces and maintain its aesthetic appearance for longer. The hypoallergenic resin interior improves comfort and reduces the risk of irritation. This is especially important when wearing the device for many hours a day. IP68 water resistance allows you to use the ring while washing your hands, exercising, or in contact with water without having to remove it.

How to choose the right size

Choosing the right size is crucial for comfort and measurement accuracy. To do this, simply wrap a thin string or thread around your finger, mark the point of contact, and measure the length. Compare the result with the size chart. This model is available in sizes 8 (18.1 mm), 9 (18.9 mm), 10 (19.8 mm), 11 (20.6 mm), and 12 (21.3 mm), allowing for a wide range of users. For greater accuracy, it's best to measure in the evening, when fingers are naturally slightly larger than in the morning.
