If you’ve ever had a DWI, you know you don’t want another one. A second offense in New Hampshire means losing your license for three full years, and a third offense means losing it indefinitely. Luckily, as the saying goes, there’s an app for that. In fact, there are several iOS and Android apps designed to keep you from getting behind the wheel when you’ve had a few too many.
The simplest sort of app for drinkers is the blood alcohol content (BAC) calculator. These programs do just what they promise: they calculate your blood alcohol content and let you know if it’s safe for you to drive. Most of them ask you to provide physical details—height, weight, gender, age—and a list of what you consume over the course of an evening. It’s only an estimate, but these apps can give you a sense of how much alcohol is in your system at any given moment. Some even have an element of fun to them. EndDUI includes several games which test your ability to focus.
For those looking for more accurate BAC numbers, there are also breathalyzer apps out there. These require you to buy additional devices, but you can get a reasonably accurate reading simply by breathing into the equipment.
Finally, of course, the easiest way to avoid drinking and driving is not to drive at all. Some of the best apps out there for keeping you offer the road are the ones that find you rides. Uber and Lyft work great if you’re looking for rideshare companies. If you live in the city, CityMapper can help you find public transportation. Yet another option is SaferRide. This app allows you to call someone from your list of friends to come and pick you up. It even includes a button that will tell you where you are, so you can let your driver know how to find you.
