Breathalyser BAC calculator

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.
