Add your recipes for your drinks. Register your intake. The app performs a theoretical calculation of the time it takes your body to process alcohol.

The recipes can be detailed eg Mojito, Havana Beach ... or simple eg wine 12%, beer 5% ...

You easily mark what you have been drinking and the amount.
Alternatively you can do a registration without a recipe.

When you finish your registration, the app calculates the time it takes for your body to break down the alcohol based on your gender and your weight.
