Bacalizer is a free Android application developed by Mike Silver that allows you to calculate your blood alcohol levels and estimate the time when you will reach sobriety. The app is designed to be a guide as every human body has a different metabolism. It uses the modified algorithm of Erik Widmark, which is extended by calculations based on the state of the stomach during alcohol consumption.

The application features a user-friendly interface that allows you to manage your alcohol intake and data required for the calculations. The parameters affecting the number of per mille in your body include gender, body weight, height, the amount of pure alcohol in grams, duration, and saturation of the stomach.
