The Body Tracker is exclusively available in the Pro version. It allows you to track and graph anything that can be expressed as a number. Among the infinite possibilities are: weight, bicep measurement, calories consumed, calories burned, miles jogged, amount of supplements taken, protein intake, etc.
There are some default measurements but you can easily define your own. Measurements that are not used are not displayed in the first summary screen which will avoid clutter.
We recommend that you enter your height at least one time, even if you know it won't change. With weight and height values available, GymACE will automatically calculate and graph your Body Mass Index (BMI).
If you own a Withings (Nokia) Body Scale, you can connect it in the settings.
