Untappd is a beer drinking app for your smartphone, you can also use it on a browser
This app lets you track the different beers you try.
You check into a beer, you can rate it (out of 5), add your location, take a photo, make a note 140 characters, and then share this information with your other social networks – Facebook, Twitter and Foursquare.
One cool feature of this app is you earn badges for checking into beers. Yup thats gamification for just trying new beers, no point in just drinking the same green bottled lager everyday. (here are the badges you can earn)
