Chips and sensors
The ring’s main chip is the Realtek RTL8762 ESF, which processes data and handles communication with the mobile app. A Vcare VC30F sensor measures heart rate, while an STK8321 sensor records movement. Together, their readings help track activity and selected health indicators.
The ring’s measurements are indicative and do not replace medical diagnosis. If you have health concerns or questions about your readings, consult a healthcare professional.
Material, colours and sizes
The COLMI R10 has a stainless steel body and comes in black, silver and rose gold. It is offered in sizes 7 to 13.
Before choosing a size, measure your finger circumference and compare it with the ring’s sizing chart. A good fit matters both for comfort and for keeping the sensor in contact with your skin.
App and compatibility
The ring uses Bluetooth 5.0 BLE to connect wirelessly to a smartphone. It is compatible with devices running Android 5.1 or later, or iOS 8.0 or later.
The QRing app provides statistics for reviewing health and activity data and offers a Slovak-language interface. Before using it, check the app’s permissions and personal data processing policies.
IP68 and 5 ATM water resistance
The COLMI R10 carries IP68 and 5 ATM ratings. IP68 covers protection against dust and immersion under specified conditions; 5 ATM indicates resistance to water pressure. The ring is intended for situations such as showering and swimming, but the ratings do not guarantee protection against damage in every encounter with water.
Resistance conditions can vary. Hot water, soap and wear may affect protection, so follow the manufacturer’s instructions.
Battery and charging
Battery capacity depends on ring size: smaller sizes have a 15 mAh battery and larger sizes have an 18 mAh battery. The charging case has its own 200 mAh battery and can recharge the ring up to 13 times. The actual number depends partly on the ring’s battery capacity and charging losses.
The ring can be charged in the case or with a magnetic cable. The case is particularly useful when travelling without a power source nearby. The available information does not specify the ring’s runtime on one charge or its charging time.
The COLMI R10 combines heart rate and motion tracking in a discreet ring format. When choosing one, pay attention to sizing, phone compatibility and the conditions for use around water.
