During the Texans Raiders game last night I downloaded the WinView Games Ultimate Live Football Predictions app on my android phone. This is a real time app that lets you make predictions live during the game. You enter a contest by choosing a football game from the lobby schedule and then you join a free competition room (20 people). All you have to do next is predict the plays on the field in real time.
It is very interactive, and the options can be as simple as deciding if the next play will be a run or a pass.
