Good Looking, Easy to Use

Id give this app 4 stars instead of five, except Ive tried a few other options and like this guy the most by far. To paraphrase the Simpsons: this app is not quite breakfast and its not quite lunch but it comes with a slice of cantaloupe at the end. You dont get everything that you would with breakfast but you get a good meal.
Anyway it wont tell you any rules, it doesnt really do anything except let you input data, and change formatting a very little bit. It also has no easy way to dump in data--you can email sheets around but they all have to be hand input by someone originally AFAIK.
But to reiterate, by far my favorite of these character sheet apps.
