Your Vyvo device constantly gathers data which is analyzed to determine your energy levels and disposition based on your Heart Rate Variability (HRV).
This HRV is composed of data from respiratory rate, heart rate, blood pressure, sleep, standing time, steps, and calories.
Vyvo Devices constantly monitor these data and send them to the App, where an advanced algorithm analyzes it and provides you with your energy level for the day.
The Energy feature is available on:
