Maryland develops ENDUI app to estimate blood-alcohol levels, prevent drunken driving

The state of Maryland is getting into mobile app development with ENDUI, an app aimed at preventing drunken driving. It helps users estimate their blood-alcohol level and offers two games to test their cognitive abilities.

ENDUI (pronounced “End DUI”) includes a number of features, including a button that dials 911 so the user can report a drunken driver, a user-generated list of designated drivers, a cab or public transportation finder, and facts about DUI.

There’s also a blood-alcohol estimator (the app says this is for educational purposes only), which asks the user to entire their gender and weight, as well as the number and type of drinks they’ve recently consumed. For example, a 160-pound male who had a double shot of 151 an hour ago would have a blood-alcohol level of 0.10, above the 0.08 Maryland limit. “Get a cab, use your designated driver, or get a ride home with someone who has not been drinking,” the app says.

There are also two games to test your reaction time and concentration. The former asks the user to tap a red “Brake” button as soon as they see certain objects appear in their way; the latter asks the user to repeat a sequence of road signs that light up and make noises, sort of like a game of Simon.

ENDUI is funded by the National Highway Traffic Safety Administration and was developed by the Maryland Highway Safety Office for $50,215.

Maryland Remembers, an annual memorial honoring the state’s citizens killed by drunken drivers, estimates that 152 people were killed in impaired-driving-related crashes in Maryland last year.

New York, New Mexico, Colorado and California are among other states with similar apps.

ENDUI is available for Android and iOS devices. So far, user reviews appear mostly negative.
