An easy way to avoid drunk driving? There's an app for that.
"Stay in the Blue" has been developed and launched by three University of Michigan students: Steven Coffey, Roddy Hyduk and Jenn Angell.
How it works:
App users put in their gender and weight. They then punch in drink types -- even those that are tailored to local bars and restaurants.
The app then calculates blood-alcohol content (BAC) over a period of time.
As drinks get entered, a BAC gauge moves from being in the "blue" to "maize," "orange" and finally into "red."
"Stay in the Blue" refers to keeping a person's BAC below 0.06 percent.
Michigan's legal limit is 0.08.
The app also has taxi information.
It's available for free in iTunes and is slated to be available in October for Android users.
