CoachPad is an app for iPad to help coaches to develop their strategies or plays and to study their opponents. The app does not focus only in soccer but also in other kinds of collective sports, bringing to the coaches different possibilities of interaction and customization. A differential point here is the focus on the referee. The other apps in the market usually ignore the referee, but here he is also one of the most important elements of the game. The app can also be used to study and to evaluate the participation and position of referees during a match or in a special play. Currently the project is in a development phase to be launched soon in the AppStore.
