Product Description
One Ring to Rule All Vitals
In the world of digital health, smart ring is less about leading you into ‘Mordor’ and more about guiding you towards better health awareness. It’s your personalised ‘Elrond’ for health tracking, taking a back seat while keeping a close eye on you.

Any part of the body with blood flow can detect PPG signals, and the earlobe, fingertips, and finger pulp have the best signal quality. The ring shape is more accurate compared to other wearable devices.

Fashion, Exquisite and Technology
In blood-related detections, the ring shape fits the skin better than the traditional wrist device. This ensures accuracy and avoids interference, while also providing good acquisition of raw data such as blood volume wave (PPG). Additionally, its small size and portability make it easier to wear and monitor daily.
