Quick note because people have been asking.
The Android app for Tales of the Cocktail 2012 is available in Google Play Store. If you had the previous app installed, you should simply be able to update. Otherwise find it here.
This year the app is also available for iOS. You can find it in iTunes
It was very interesting building the iOS app. A lot of pre-held myths about developing for iOS were shattered in the process. In fact I've been (gasp) doing quite a bit more iOS dev over the last 6 months than Android dev. If I get time I may make a post or two about it.
Enjoy the apps!
