BACtrack Mobile Smartphone Breathalyzer for iPhone and Android Devices

3.9 out of 5 stars 326 customer reviews

About the product
  • #1 RATED SMARTPHONE BREATHALYZER - "Comparing smartphone breathalyzers against the $890 unit used by the California Highway Patrol, only one was spot on with the police-grade model... BACtrack Mobile. My first test, the officer declared my BAC an official 0.048. Of all the units tested, BACtrack Mobile came the closest with 0.047. My next test, I had exceeded the legal limit on the Alco-Sensor IV with a 0.092, while BACtrack Mobile checked in at 0.091." - The New York Times
  • POLICE-GRADE ACCURACY - Powered by BACtrack's platinum-based Xtend Fuel Cell Sensor, BACtrack Mobile utilizes the same police-grade technology trusted by hospitals, clinics, and even law enforcement. These professional organizations trust BACtrack breath alcohol testers because they know they are getting the most accurate and reliable BAC results possible. BACtrack Mobile can detect trace amounts of alcohol, reliably handles high BAC levels and is accurate to the third decimal place.
  • POWERFUL APP-ENABLED FEATURES - Quickly and easily estimate your blood alcohol content (BAC), save and track your results over time, and with ZeroLine, estimate when your BAC will return to 0.00%. You can even call an Uber directly from the BACtrack App if you've had too much. You choose how much, if any, is saved on your device. Note: All sharing settings are turned OFF by default - you much choose to turn these ON.
  • ZEROLINE TECHNOLOGY - With BACtrack's innovative ZeroLine technology, you're in control of your night. After your BAC results are delivered, ZeroLine estimates the time until your BAC is 0.00%, allowing you to quickly and easily know where you stand. You might be surprised at how long it can actually take for your body to metabolize the alcohol in your system! Apple Watch users can utilize the Active ZeroLine™ feature, which offers a continuous countdown to 0.00% BAC available at a glance.
  • 30 DAY MONEY-BACK GUARANTEE & ONE YEAR WARRANTY - BACtrack is the global leader in breathalyzers, providing the most accurate, convenient and affordable breathalyzers on the market, since 2001. We stand by all our products, but if you are unhappy with your BACtrack, you may return it any time during the first 30 days. All BACtracks also come with a full one year warranty, should you have any issues during your first year. Please contact BACtrack's customer service team for more information.
