As to the App, I believe you have to pay Apple $99 to be a publisher. Not sure about Android. We are (with some occasional contributions every so often from members and staff) completely funded by our webmaster's wallet.
I visit the site a lot on my iPhone, and have thought about it, but I just don't see the demand to make it profitable, or even break even. I might be wrong though.
And regarding Audalis: Yes, we have been considering publishing for many years now, but since so much of the world is just not fleshed out (so many places are just names on an outdated map) and doing said work is basically the collective hobby of a group of very busy nerds... it's going to be a while.
I'm not going to lie, the contests are probably some of the biggest ways we get new material. We rely heavily on equally busy members to write material. Also *wink wink hint hint* lol
Bottom line: enter the contest!
Good suggestions though! I'll look into the app thing more.
