Once you have imported your teams and are happy with your events for the live game you wish to tag, simply create a game.
When the game commences hit the Start Game button and and events as you see fit. Use your thumbs to tap on the event you wish to tag and follow the outcomes as you see fit. This starts to create time stamps and begins to create a profile of the live game you are watching. Remember if you wish to tag an event for an opposition team double tap the event so that the tag changes to a blue colour - this is a indication that you are tagging for the opposing team and not the home team.
