Circular Ring Slim: One minute review

The Circular Ring Slim is a smart ring packed with sensors. It’s designed to be worn 24/7 and collects data about your heart rate, breathing, temperature, SpO2 levels, sleep, steps and more. Unlike other smart rings, it has a vibrate function too, enabling you to set alarms. Think of it as a fitness tracker designed to collect data from your finger, rather than your wrist.
