Samsung Galaxy S4 A must use app. THINK BEFORE YOU DRIVE!!!!!!! This app could be better if the features were easily accessible. I had trouble calculating BAC and I am sober. The arrows to change weight and hours are very sensitive. If you mean to touch down you are going up. Also, as I was going through the "Know your rights" section, I would go to scroll and it would take me to the previous screen. Making this app "drunk friendly" is a must with the size of the buttons to make your choices. Good app otherwise
This is a necessary app for anyone who has a drink socially anytime anywhere This is the responsible app to have. Being INFORMED is what it is all about, an option to call a Taxi and help if you don't ALL RIGHT IN YOUR PHONE!
This really works!
