A mobile breathalyzer can help you make smart decisions next time you're out on the town.

The gadget estimates both your blood alcohol content (BAC) and how long it will take for you to get back to 0.00%.

This will help you plan out your evening: you'll be able to know if you can keep drinking, or if you should stop.

The breathalyzer easily connects to both iOS or Android smartphones via Bluetooth.
