This is the ultimate red/yellow card app to judge if a foul deserves a red or yellow card. It is a really simple app that does take minimal disk space.
Fans in the arena can use it to influence the referee.
Hobby referees can use it if they forgot their cards.
Jokingly, you can use it on your friends if they do something wrong.
This top entertainment app will be a lot of fun, and when used massively in an arena it could have a massive effect on the referee!
Download it now, soon it wont be free anymore!
