This is an entertaining, and perhaps even useful, app used to estimate your blood alcohol level.

A friend showed it to me last night during happy hour - he had a 45 minute drive to look forward to and wanted to keep track of what he was drinking.

You tell the app your gender and weight, and then each time you have a drink you note it on your phone. There's a menu that let's you choose from different beer styles, cocktails, etc.

The app keeps track of elapsed time, and combines this info with the estimated alcohol intake + your physical profile to chart your blood alcohol level.

There's also an "intoxicated?" tab that provides helpful links to taxis and DUI attorneys.

The only thing missing is a leaderboard, and a "share this cocktail" to Facebook button.
