    Great piece of tech that allows me to track my sleep and stress levels. However, make sure to open the app. I recently got sick and just kind of sat around all day, and it wasnt until the evening when I checked the app, it ended up registering that I slept all day.

    Love how I can tell if my body responds to a late meal or high sugar meal by noting elevated resting heart rate. I am using this ring to become more in tune to how my body reacts to various foods and rest…or lack thereof. Very accurate.
