BACtrack Mobile Smartphone Breathalyzer for iPhone and Android Devices

I use this after EVERY tasting to make sure I'm good to drive. This breathalyzer is police-grade. App works great and it will tell you what time you will be sober. I really believe every one should have one of these. All my friends know, I make them use when we are leaving a bar or party if they are driving (or just for fun to see who is the most drunk if we are ubering). xx C ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~   Brand: BACtrack Color: White Features: #1 RATED SMARTPHONE BREATHALYZER - "Comparing smartphone breathalyzers against the $890 unit used by the California Highway Patrol, only one was spot on with the police-grade model... BACtrack Mobile. My first test, the officer declared my BAC an official 0.048. Of all the units tested, BACtrack Mobile came the closest with 0.047. My next test, I had exceeded the legal limit on the Alco-Sensor IV with a 0.092, while BACtrack Mobile checked in at 0.091." - The New York Times POLICE-GRADE ACCURACY - Powered by BAC
