With the help of a skin fold measuring device (Caliper), your body fat percentage can be determined very precisely by measuring the subcutaneous fat tissue at defined body parts. It is important that you measure with a high-quality caliper – such as the the eaglefit® Slim Guide Caliper – that will apply the same force to the skin fold to be measured at any opening angle.
There are different measuring methods, which calculate the total body fat percentage approximately from 3 to 9 measured values. In the app you have the choice between 6 different methods. Once you have decided on a method, the app tells you where to measure the thickness of the respective skin fold. After measuring and entering all values, the app uses the previously selected algorithm to calculate your average body fat percentage, the weight of your muscle mass as well as your fat mass and allows a comparison with previous measurements. This allows you to track your body fat percentage over several weeks, months and years. 

The "Health Integration" with the Apple Health App enables the analysis and further processing of the data.
