Fit to Drive app

This app attracted my attention a few days ago. It is basically a breathalyzer on your iPhone. The main feature of it is 'are you fit to drive', where you do a series of tests on which it will then calculate your age and say if you're fit to drive. The other feature is a calculator on what you have drank. You will have to put in your age and your weight, then you will have to put the amount you have drank so far. It will then calculate the amount of calories you drank, what it is equal to and how much you have to run to burn it off. Also it will calculate the stuff you can do and the stuff you cant do and when you will be sober.

Overall it is a good app that will come in handy one night that you decide to drive home after you have had a few. It is available for free in the App Store.
