Make Better Decisions While Drinking
When it comes to alcohol, there is often a significant difference between how you feel and how impaired you actually are. BACtrack helps eliminate that uncertainty by giving you an actual number to put with that feeling, empowering you to make better decisions while drinking.
Guess Your BAC
Before each test, you are given the opportunity to guess your BAC level. Compare your perception to actual numbers, and see whether your guesses get better over time.
Track Your Drinking
Save your previous tests, attach notes or photos to your results. Track your drinking habits over time and learn how alcohol affects your body under different circumstances.
Rideshare Integration
Remember, the only safe time to drive is when your BACtrack shows 0.00%. Anything above that? You can call an Uber directly from the App.
"People know they shouldn't drink too much alcohol, but they do. People also know they shouldn't drive if they have been drinking, but they do. To be on the safe side, try this breathalyzer. It is accurate and it will let you know when your blood alcohol has dropped to 0.00% before you can drive."
