Beer Tracker

"One of the 30 beers yesterday must have been bad" is a line from the song "Kreuzberger Nächte" by the Blattschuss brothers from 1978.

But would anyone still have been able to count all those beer bottles? Now they can, because now there's the Beer Tracker, which acts as a bottle opener and counts the opened bottles at the same time. So in future there will be no more cheating. Or you can simply switch to canned beer...
