    A combination of a virtual breathalyzer and a calories calculator.

    A simple program, that is a combination of two applications - a blood alcohol content calculator also called a virtual breathalyzer and a calories calculator. It should be noted that the author is not a nutritionist and does not have a deeper knowledge of the principles of absorption of alcohol. Therefore, the two applications are based on simple algorithms, which are, however, widely used in similar calculations, also in similar calculators available online. The program takes into account a number of factors to produce outcomes as close to actual results as possible. However, the calculations are based on mathematical algorithms and therefore results may differ from reality. Thus, the author is not responsible for the consequences of its use. Download options: - complete application with all the source code as well as jar and exe files. - exe file only. To run the project use Kalkulatory.jar or Kalkulatory.exe. See wiki for a full project description in polish.
