Too many drinks? New cellphone app may tell you so

A new federally funded cellphone app allows people who may have had one too many to get an idea just how drunk they are -- and hail a ride home.

Users enter their sex, height, weight, and number of drinks consumed to help figure out their blood-alcohol level. They also can play two interactive games to test reaction time and cognitive agility. And the app uses GPS technology to call cabs and pre-load phone numbers for potential designated drivers.

The app, called ENDUI -- pronounced "End DUI" -- was announced Thursday by government and police officials in Maryland. Funded by federal money reserved for drunken-driving education efforts, the app is among several in a handful of states to tackle drunken driving -- though Maryland's is one of the most elaborate.
