Wiesen 2012 is an amusing way to navigate through the 14 festival halls (popularly known as "beer tents"), 15 small tents, and 114 kiosks selling sweets, fruit, souvenirs and coffee at Oktoberfest. The list of tents include details about the managing brewery and beer price. Other than the €14.60 wheat beer sold in the Weinzelt Tent, the average price for one liter of beer is €9.35 this year - 43% more than one liter of Oktoberfest beer in 2002, according to the City of Munich's official site. The app's cartoon icons can be deceiving, but Wiesen 2012 includes extensive information on the festival to enrich visitors' experiences at the Oktoberfest. It includes a map with directions to amusement rides, attractions and activities around the fairgrounds, another map directing users to local nightclubs, a weekly weather forecast, transport information, beers, and beer prices from each year and a festival program, beginning with the opening ceremonies on Sept. 22 to the closing on Sunday Oct. 7. The app also includes a dictionary of Bavarian terms and a live video of the festival grounds. The most entertaining, but arguably most useful, feature calculates users' blood alcohol level based on the time of day the first beer was consumed, the number of beers consumed, and the user's gender and weight. This free app is compatible with iPhone, iPod touch, and iPad, but requires iOS 3.0 or later.
