Ivy automatically tracks your sleep so you know how long and how well you sleep. See the percentage of light and deep sleep you have each night and learn about your sleep quality.
Ivy tracks your sleep and sleep patterns with a 3-axis accelerometer and your heart rate data with an optical heart rate monitor. Within the IVY app you are able to see a detailed breakdown of your sleep which includes information about your deep sleep, light sleep, and awake periods.
During the night, Ivy also tracks your resting heart rate and your respiratory rate, as well as your cardiac coherence. This information impacts your Readiness score which is available on the Readiness screen.
