User comment: Fantastic! Settling the argument with my observing friends over which of our sites is better is worth the $5 all by itself. And if I win the wager for a beer, it will be like getting the app for free.

Hi, my name is Norbert and i am developer of the app, database map and website. It is a voluntary project (i don’t make money out of it, the income is just enough to cover the hosting costs). So my time for support is somewhat limited. Replies can take long. I hope you understand.
