I know many of you have probably seen that phony breathalyzer app you can get for your mobile devices. That app is a fun toy to play with at the bar, but really provides no solid feedback on whether or not its safe for you to drive after that extra shot of Jameson. The Breathometer is the first official breathalyzer for your smartphone. All you have to do is plug this little device into your headphone jack on your phone, and blow into the end of it. The Breathometer gives you a fast accurate BAC to determine if you've had one too many drinks. The only thing that would make this better is if it flattened your tires when you are too intoxicated to drive.
