Drinking Buddy is an estimated Blood Alcohol Content (BAC) calculator. Not a breathalyzer.

It calculates an estimated BAC based off the Widmark formula. All drinks added are standard drinks and are defined as:

12 fl oz of a regular Beer (5% alc/vol)
5 fl oz of wine (10-12% alc/vol)
3 fl oz of wine (16-18% alc/vol)
1.5 fl oz of spirit(40% alc/vol)

Tips:
-click on 'Time' to change the elapsed time
-click on 'Sober' to change your definition of sober (the default value is a BAC of 0.00)
