You can add drinks to this application in real time to see how drunk you are and how drunk you will be the next hours until you become sober. The app calculates your estimated BAC (blood alcohol concentration) based on a formula that has been studied and praised in scientific papers. You can set a limit on how drunk you want to become, and the app will warn you if you are about to cross that limit. In order for the app to be as precise as possible, you will be given a choice to enter information such as your gender and more. Please note that the BAC given in this app is just an assumption and it might not be relevant to you since many factors can play a part in how drunk you actually are, such as how much you have eaten before drinking. However, there is a parameter supplied within the app where you can tweak the formula slightly.
