App Description

BAC calculator - calculate after what time the body will be sober.

Bacalizer is an application that allows you to estimate after which time your body will reach sobriety. Because every human body has a different metabolism, the results should be treated only as a guide. If you want to be 100% sure, use a real breathalyser.

Our promille calculator uses the modified algorithm of Erik Widmark (extended by calculations based on the state of the stomach during alcohol consumption)

Application features:
✨ Calculation of blood alcohol levels and the time when we reach sobriety.
✨ Alcohol management.
✨ Data management required for calculations.

Description of the parameters affecting the number of per mille in our body:
✨ Gender - alcohol dissolves in body fluids, the content of which depends on gender.
✨ Body weight - it is needed to calculate the mass of body fluids in the body.
✨ Height - required for calculating the BMI of our body, which allows more accurate calculation of the mass of body fluids.
✨ Alcohols - the amount of pure alcohol in grams is required for the calculation.
✨ Duration - for the result to be reliable, the dose must be spread over the duration of alcohol consumption.
✨ Saturation of the stomach - whether we drink on an empty or full stomach has an impact on the absorption of alcohol into the body.
