This is the wellness monitoring ring that tracks blood oxygen levels, heart rate, and sleep quality. The smart device adjusts to the size of your finger for comfort during daily activities, exercising, or sleeping and transmits the information to a free app on your smartphone or tablet. It monitors your heart rate and blood oxygen saturation (SpO2) and can record workouts as well as count your steps. At night, the device also monitors your sleep quality by tracking your stages of sleep and detecting changes in blood oxygen and breathing due to sleep disorders or snoring. A two-hour charge via AC provides up to 16 hours of power. S/M (ring sizes 5-9), M/L (ring sizes 9 1/2-12), or XL (ring sizes 11 1/2-13 1/2).
