Master Coach allows easy data transmission thanks to its Wi-Fi connection. It is not necessary to weigh yourself with your smartphone, as transmission to your smartphone is automatic with the Wi-Fi connection. Master Coach analyzes your weight, Body Mass Index (BMI), and body composition, including body fat, muscle mass, body water, and bone mass. This is useful when you are monitoring your weight. The data analysis is available directly on the Wellness Coach-Health application, allowing for complete tracking of your weight. Three months of slimming coaching are offered with every Master Coach purchase.
