I downloaded the app because the user interface does make it very easy to track player action, while the game is happening. I bought the full version, as that allows to track members of multiple teams.
But it doesn't work. You cannot enter a jersey number higher than 19. You can't edit a team roster once you've created it. Worst of all, the stats you've just spent record, don't save correctly. If you want to go back and check individual player or team, the stats are completely wrong, as if the app made them up on its own! I spent $3.99 for the full version, and I want a refund.
