Today marks the first day of October, and that means the Munich Oktoberfest is coming to a close. Yep, there are only two days left to celebrate among the six million people who travel to Germany to get drunk and loose at one of the world's most famous festivals. No worries, though: There are a bunch of fake ones about to take place all over America. And even if you can't attend those, you can still get twisted on your own or with friends and have fun using some iPhone drinking apps. From drinking games to breathalyzers, the iTunes App Store offers several apps catered to all beer drinkers. So, in celebration of the end of Oktoberfest and our own NY Craft Beer Week, we present the 7 Coolest iPhone Beer Apps. Drinks are on the house!
