## What is Alcooler?

Alcooler is the best alcohol concentration measuring application.

The application logs the time you started drinking alcohol and calculates the alcohol concentration. 

It can be used to manage your health and your time. (for driving, work, etc...)

There are two types of lines displayed in the graph
- The red line disappears after 4 hours (per 1 unit)
- The blue line disappears after 6 hours (per 1 unit)
(1 unit is the amount of alcohol you take in a 500mL can of beer)

The calculation method used in this app is called "Widmark method". This method is used in several judges, and it is the most accurate method to calculate alcohol concentration.

The red line is showing the graph of people who are especially weak at alcohol, and the weight is 41kg. (The heavier you are, the faster speed alcohol disappears.)
And the blue line is showing the graph of people who are especially weak at alcohol and the weight is 28kg.
