The BACtrack Vio Smartphone Breathalyzer has to be one of the coolest breathalyzers on the market. By using your smartphone as the display for your blood alcohol content (BAC) you can do some pretty cool stuff. For example, the BACtrack Vio can track your BAC results over time and give you an estimate of when your BAC should be back to 0.00%. Curious what your BAC was last night or last week? It can do that as well. You can even attach pictures, notes, drinks, etc… for some interesting history lessons. The BACtrack Vio even integrates with the Apple Health app. Video of the BACtrack Vio after the break.
