Mobile app for the community. Ideas.

I mostly use the guard calculator, and then probably the library website (physics department). If all of this were in an app, it would be great. Regarding the lobby rating and other things, I don't think the rating itself deserves to be displayed yet. We need statistics on templates, heroes, castles, and other things; then it would be interesting to study the rating. As it is, it's just numbers to look at.
