ColMi R02 9

The smart ring in a minimalist design mirrors the functionality of fitness bracelets. The only difference is that the device is intended to be worn on the finger rather than the wrist. The ring pairs with mobile devices via Bluetooth v 5.0 wireless communication protocol. It transmits data about user activity and key health parameters to the linked app. The ColMi R02 9 measures pulse, determines saturation level (oxygen saturation of the blood), tracks the number of steps taken, and roughly estimates the calories burned.

Additional functions of the model include sleep monitoring and stress level control. The device's body, which is 2.7 mm thick, houses a lithium-polymer battery with a capacity of 17 mAh, providing up to 7 days of autonomous operation. The ring features water resistance of 30 WR / 3 ATM and an IP68 dust and moisture protection. The model is available in three color options: black, gold, and stainless steel.
