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.



Personalization

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.



ZeroLine®

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.




Apple Health

Integrates seamlessly with Apple Health so you can see your total health picture and assess how alcohol may influence factors such as sleep and activity level.


Proprietary Sensors

Provides the most accurate results because of our sensors: professional-grade Xtend® fuel-cell and reliable MicroCheck sensor technology.





Mouthpieces

Includes washable, disposable mouthpieces to improve accuracy by collecting the highest quality sample, and to allow you to test others safely.
