Buzz Buddy for iPhone

From Ezogo:

Buzz Buddy is the responsible drinker's companion.

Buzz Buddy helps you keep on top of your drinking by providing a fun graph of your estimated blood alcohol concentration (BAC). This provides you information on your recent BAC, as well as your projected future BAC.

How it works:

-First, answer some simple questions about your sex, weight, and earlier drinking to set a baseline graph.
-Select drinks as you consume them during the evening to update the graph.
-Refer to the graph to check your BAC. Buzz Buddy will also warn you when your BAC exceeds 0.08%.
-Press the 'Taxi' button to help call a taxi cab in your area.

Buzz Buddy is purely for entertainment. Estimations of blood alcohol concentration are never completely accurate so you cannot rely upon them for legal, health, or safety purposes. Always drink responsibly. You must be 21 years of age or older to drink alcohol in the USA.
