Can anyone recommend an app for the iPad for fantasy?

What I'm looking for:

1) Something for draft day that I can enter people's rosters right at the draft then enter it on site when I get home (Commish)?
2) Possibly a ranking sheet for myself for draft day?
3) Or anything else you recommend

The draft location doesn't have wireless or this could all be solved. We use CBS Sports for our site. Thanks in advance.......
