Better app name?

Here's a question for the crowd.

My uncle is one of a pair of developers for a great app that may save many lives: "CheckPlusBalance helps responsible people quickly, privately and accurately determine their impairment level prior to driving. CheckPlusBalance can help individuals assess their performance regardless of the cause, including marijuana, alcohol, medication, illness or fatigue."

The problem, of course, is the name. Any suggestions for a better one?

(The fact that I'm posting this should imply no disrespect to some great suggestions that we've already heard at this week's pot-luck dinner. The more, the better!)
