I just recently got this app, and I have to say it is excellent, just from the stuff I've gone through (I need to buy my schoolbooks before I can pay for the extra features).

I am baffled by the deities though. I'm surprised that they have only been mentioned twice in the comments here. I tried looking through the deities for Apollo, but when I found it I got a bizarre version that I believe came from the D&D wiki's 3.5e homebrew section. Why hasn't anybody at least put in the basic stats (name, pantheon, alignment, suggested domains, and symbol) for deities that are in the back of the PHB? I would do it, but I haven't had a chance to look at the content creator, and I won't have a chance till the end of this semester.
