This is a new free application for iPhone which should appeal to all the outoign folks. Last Call is to be taken with a touch of humor anyway. This application allows you to calculate your level of alcohol in the blood depending on how much you drank, what you have been drinking alcohol and your weight. And if you exceed the legal limit, a button appears that allows you to find a taxi near you or find a lawyer in a directory if you are arrested by law enforcement. Funny but it will be reallu useful if you will need it.
