That’s old hat! With Wiesn FindMe you can simply use your mobile to mark your current position or a place to meet on the Oktoberfest map and then send a picture of it to your friends. This even works without GPS! And in case the outline map of the Oktoberfest is not sufficient Wiesn FindMe also has detailed views of many large tents!
So just mark your position, share with friends and enjoy the party.
