Best scoreboard app available

You have all the following abilities that they dont show how to do or disclose:

Keep scores of all different sport/activities

Can change team names

Can broadcast the game scores live over the internet so you can show it on a projector and have people watch scores from anywhere

Can give and take away points. Took me a while to figure out, swipe up adds a point, swipe down takes off a point.
