How to use
Wear the Smart RING PRO on the finger that provides the best fit for size 11 and ensure the sensor surface maintains contact with the skin.

Regular wearing during daytime and sleep provides the most consistent trend data.
Usage recommendations
For reliable readings, wear the ring snugly but comfortably and keep the sensor area clean and dry.
