If you're a dedicated beer geek, chances are you're using the app Untappd to track your libations. For the unfamiliar, the mobile software allows you to log and rate beers while following what and where your friends are drinking. With a new update to the iOS version, the app is getting a load of new features. First, there's a new barcode scanner that'll make searching for beers you're drinking a breeze. Rather than having to manually search, all you'll have to do is point your phone's camera at the barcode on a bottle or can.
