Great device to make sure you're safe! I've had it for a few months and love it. It is small, easy to use, connects with my iPhone and just works.

James S., Redwood City, CA

It is highly accurate and I love that it forecasts the time period for your body to metabolize the alcohol out. It has been a great tool and a HUGE eye opener for me.

Accuracy You Can Trust

Xtend® Fuel Cell Sensor Technology

Engineered from technology used in experimental vehicle fuel mixing, BACtrack Mobile utilizes proprietary platinum-based Xtend® Fuel Cell Sensors which deliver the most accurate, consistent BAC results, with police-grade accuracy.

Advanced MicroCheck® Sensor Technology

The Vio employs BACtrack's proprietary Advanced MicroCheck® Sensor Technology. Using a semiconductor as a base, these sensors go through a patented burn-in process, which delivers more accurate and reliable results, when compared to standard semiconductor sensors.

Optimal Breath Capture

Breathalyzer accuracy begins with an effective breath capture mechanism. BACtrack breathalyzers are carefully designed to exclude ambient air, fumes, and other airborne gases that could contaminate results. To enhance accuracy, BACtrack Mobile features a miniature solenoid air pump to test only air from the deep lungs.


BACtrack smartphone breathalyzers are compatible with iOS devices, including iPhone and iPads, as well as most Samsung and Google devices. It is also fully compatible with Apple Watch, where your BAC results are sent directly to your wrist. And with the new Active ZeroLine™ feature, you can view a continuous countdown of your BAC at a glance. See full list of compatible devices below.

Apple Health Kit

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.

Instantly Connect to the App in Seconds

Utilizing Bluetooth technology, BACtrack smartphone breathalyzers seamlessly connect to your iPhone or Android smartphone. Connecting is easy - simply open the BACtrack App (after downloading from the iTunes or Google Play stores), power on your breathalyzer, and voilà, the app automatically recognizes your device!

Learn How Alcohol Affects Your Body

While your BACtrack is warming up, you are given the option to guess what you think your BAC will be. The App will let you know how close you are and if you're improving over time. This isn't just some fun party trick - after using your BACtrack regularly, you'll notice that you are much better at knowing how alcohol affects your body.

Estimate When Your BAC Will Return to 0.00%

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 eliminate the alcohol in your system!

Privacy and Sharing

Your BAC results can be as private or as public as you want them to be. Simple privacy settings put you in control over what data is saved, if any. Choose to share readings privately via text message with a friend or family member, along with photos, location and time. Note: All sharing settings are turned Off by default - you much choose to turn these On.
