Can you keep stats on both the iPhone and iPad for the same game at the same time? For example, it is too hard for my stats guy to do everything and still watch any part of the game.i am trying to find a second person to do defensive stats and let him focus on offensive stats. Any ideas?

You can both keep score, but the stats would not be "combined" for the game. It would look like two separate games. If you each kept track of different things, you could get a report from each game to see the different stats.

I score is built as a single user app.
(It would be far to complex at this time for a 10$ App to be multi user app that allows merged scoring)
