It can seem somewhat abstract to know just how much you can drink before being able to get behind the wheel (the safest amount will always be none), so the BACtrack Vio breathalyzer keychain is designed to help you quickly track your intoxication level.
The keychain incorporates a law enforcement-grade sensor within that will provide you with an estimate of your current blood alcohol content (BAC) and relay the information via Bluetooth to your smartphone. The accompanying app will then give you a rough estimate of when you'll be sober enough to drive thanks to the ZeroLine technology it sports.
The BACtrack Vio breathalyzer keychain is ultra-portable and ensures that drunk driving and even buzz driving isn't something you partake in.
