Get 20% off the BACtrack Vio Smartphone Breathalyzer (available worldwide)

So you’ve had a drink or two – but are you really okay to drive? The BACtrack Vio will let you know in an instant. Small enough for your pocket, this handy little gizmo pairs with your phone over Bluetooth to give you clear, accurate readings in seconds.

To use it, flip up the mouthpiece, blow for five seconds and check your Android or iOS device for your Blood Alcohol Content reading. The app will also estimate when your level will return to zero, so you can make smart choices about whether and when to drive.

Not only is the Vio good for figuring out how long it will take for you to be sober, but it’s also quite a bit of fun!
