In time for arguably the wildest night of the year, the Colorado Department of Transportation has launched a free iPhone application to help partygoers calculate their blood alcohol levels and call a cab.
The app, called R U Buzzed, launched earlier this month and, according to the Wall Street Journal, has been downloaded more than 40,000 times.
The application prompts users to enter weight, gender, hours drinking and the amount of beer, wine and liquor consumed. (The calculator assumes that one drink is equal to 12 fluid ounces of beer, 5 ounces of wine or 1.5 ounces of hard liquor.)
Then it calculates and displays a blood alcohol content number. Even if you're under the legal limit of 0.08 percent, it might say "You're buzzed!" and warn you that "You could be arrested for impaired driving. Designate a sober driver."
The app includes a disclaimer that the estimates aren't accurate enough to be considered legal evidence. It also says that individuals may vary in alcohol tolerance and may be influenced by food, medication, health and psychological condition.
A GPS feature also helps users locate a taxi. But non-Coloradoans take note -- because the applications was built for the state Department of Transportation, estimates are based on Colorado law and the GPS feature may not work for out-of-staters.
The Colorado Department of Transportation also advises that the best plan is to designate a sober driver before people start drinking.
R U Buzzed is just one of about 100,000 applications available in Apple's App store.
Here is a sampling:
If a fear of flying keeps you grounded, Virgin Atlantic has a new iPhone application just for you.
Launched in partnership with developer Mental Workout, the new application is based on (and named after) the airline's Flying Without Fear course, which the company says has a 98 percent success rate.
The application, available for the iPhone and iPod Touch, includes relaxation and fear therapy exercises, frequently asked questions and a video that explains a flight from start to finish.
It even features a "fear attack button" for emergencies, with breathing exercises and quick tips.
"Our first iPhone app will bring the benefits of our successful Flying Without Fear course to millions of people around the world who are now using mobile technology to make their lives better," Sir Richard Branson, Virgin Atlantic's president, said in a statement. "The app will put many travelers at ease and enable them to prepare for their first Virgin Atlantic flight."
At $4.99, the it's on the pricier side for iPhone applications. But as proof that the app is based on a sound program, Virgin Atlantic said its Flying Without Fear course recently helped Whoopi Goldberg overcome her fear of flying.
"The program works, I was a skeptic. I hadn't flown in 13 years but after doing their program, I understood that while my fear was real, there were many things I didn't know or had misinformation about, which they were able to clear up," the actress said in a statement. "So what happened? I now fly. It's that simple."
Recently, developers released an application that promises to remotely unlock, start and warm your car from almost anywhere in the world.
