The app "Breathalyzer" is intended for entertainment only and cannot be substituted for the licensed devices for measuring BAC. Our “Breathalyzer” can be used only for pranks. Unlike the real Breathalyzers, our application does not provide reliable results for the concentration of alcohol in blood. After entering the specific parameters of a person (gender, height, weight, age and amount and type of probable drink), you can estimate a would-be period after which somebody’s BAC results could be considered as acceptable or not for driving in a certain country. The app "Breathalyzer" has a prank alarm clock that will wake you up after a certain period, which corresponds to the supposed time required to achieve the acceptable limit for blood alcohol concentration. Using our "Breathalyzer” for entertainment with your friends, keep in mind that the results obtained by using this application cannot be considered as reliable and cannot lead to the decision whether one can drive or not. The application developers warn that, despite the fact that the this alcotester uses Widmark’s and Watson’s formula for calculations, the results can be used for entertainment purposes only, and the only way to calculate the BAC correctly is using a breath test or a blood test.
