This app is designed to calculate the blood alcohol content (BAC) of a person after consuming a certain amount of alcohol. It is based on the formula of the Swedish chemist Erik Widmark and the volume of the drink. The app provides two different modes: a detailed mode and a fast mode.

In the detailed mode, it is possible to enter the volume of the drink and the alcohol content in the formula. Furthermore, the app provides a graphical evaluation of the result. It is also possible to find additional information in the options menu.

In the fast mode, it is possible to select pre-written drinks, and it is also possible to select the type of drinks (i.e. beer, wine, or liquor).

This app is useful for calculating the BAC of a person after consuming a certain amount of alcohol. It is not intended for use as a substitute for professional medical advice, diagnosis, or treatment.
