The best way to not get a DUI is to not drink and drive. But, sometimes you don't have one or you're not sure if you are safe to drive. That's where this app comes in. It uses a similar field sobriety test to those used by police. It calculates your ability to count backwards from 15 in a set amount of time. If you can do it, you're good to go. If you pause, take too long, skip numbers or give up, the app says you are not safe to get behind the wheel. Obviously, this app is not idiot proof and should be used for entertainment purposes only.
