The only smartphone breathalyzer that employs police-grade Xtend® Fuel Cell Sensors, the same advanced technology trusted by hospitals, businesses, schools, and even law enforcement. BACtrack Mobile Pro is equipped with a miniature breath capture pump to ensure reliable and consistent results. You can actually feel the pump activate at the end of every test.

How It Works


Breath into the BACtrack and results are sent wirelessly to your iOS or Android device.



See accurate reading and a ZeroLine® estimate of when your BAC will reach 0.00%.



Decide what comes next. Save your number? Test someone else? Switch to water? Hand over your keys?

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.




Estimates when you will likely be sober, based on your last reading.

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.

Apple Watch

Sends accurate results straight to your wrist. Apple Watch features include Active ZeroLine™, which offers a continuous countdown to 0.00% BAC available at a glance.

Accuracy-Focused Engineering

We focus on our technology so BACtrack’s pro-grade series consistently outperforms.

Precise Results

The linear response of the Pro Series’ Xtend® Fuel Cell Sensor Technology provides precise results over the complete range of alcohol concentrations expected in the breath, from 0.000 to 0.400 % BAC. BACtrack pro-grades can accurately detect trace amounts of alcohol and reliably handle very high BACs.


Pro-grade models produce the most consistent and reliable results. For example, they are more likely to show the same test result when someone is tested repeatedly in a very short period of time. This means pro-grade BACtracks easily handle multiple high-frequency tests.

High BAC Testing

Pro-grade models are consistently accurate at higher BAC concentrations. If someone is very intoxicated, for example at 0.22% BAC, these models are more likely to provide an accurate test result as compared to semiconductor models, which are less accurate at higher BAC values.

No False Positives

Pro-grade models will not show a false positive due to the presence of acetone, which some semiconductor models misread for someone who is diabetic or on a low calorie diet.

Long-Term Reliability

Extended sensor life helps pro-grade models maintain accuracy for up to thousands of tests, delivering long-term reliability.

Faster Warm Up Time

Pro-grade BACtrack models offer a faster warm-up time, a benefit when conducting high volume and back-to-back tests.

Longer Battery Life

Low power requirements enable up to 300 tests on one battery charge.

BACtrack Mobile App for iPhone and Android

The power of your smartphone unlocks a variety of additional breathalyzer features. See clear and vibrant instructions and results, plus features that raise your drinking IQ.
