It is an application for measuring the posture.
You can when standing, one leg at the time, measuring the balance of the body at the time of the walk, to compare.

Because I use the acceleration sensor of the terminal, there are times when it does not work properly by the terminal.
Please refer to the manual from here how to use.Some functions are restricted when Lite.
