How It Works

Guess Your BAC

Gives you the opportunity, before you test, to guess your BAC level. Compare your perception to actual numbers, and see whether your guesses get better over time.


Allows you to track and attach notes or photos to your results. What you drank and ate, who you were with, and how you felt; personalize results to make more meaningful.

Wireless connectivity

Bluetooth enables a simple connection between BACtrack and your device so you don’t have to breathe into your phone, and you can see the app’s prompts and results as you blow.


Based on your last reading, BACtrack's patented ZeroLine technology estimates the time until your BAC returns to 0.000%, empowering you to make smarter decisions while drinking.
