Whats the best app to use for character creation?

So I'm trying to search for good character creation sheets for my iPad so it can be easier to view than constantly switching programs on the computer, but everyone i find seems to have something wrong with it in one way or another. What do you guys use? Can it export pdf's?

Moving to Off-Topic. Is there a specific system you're looking to create character sheets for?

4e

I toyed with all kinds of generators till I broke down and bought the best. Others work. And some are better than others. But this is the best I've used. <a href="http://www.wolflair.com/index.php/index.php?contex" rel="nofollow">http://www.wolflair.com/index.php/index.php?contex</a>... This isn't for iPad - but you can send your sheets to the iPad once created (for Pathfinder anyway - not sure about 4e). It can export PDFs.
