When the soccer team to which the child belongs is the game, it is always a helping referee for the coworkers!
I do want to do well if I tried anyway. RefereeLog will record your movements and will help you improve the referee skills.
If you wear it while wearing it, keep track of your movements using GPS. If you look back at the movement after the game, in the next game you may be a notch above.
Of course you can not use it in the official game, but lets improve by practicing in a match!
