What are the differences between BACtrack Mobile and BACtrack Vio?

Last Updated: Apr 17, 2019 09:21AM PDT
BACtrack’s two smartphone products both offer accurate and reliable results, and provide a user with a quick and easy way to get an estimate of their BAC (Blood Alcohol Content). Both devices use BACtrack's latest sensor technologies, employ Bluetooth connectivity, and sync with the same BACtrack companion app on iOS and Android.
BACtrack Mobile is powered by a Lithium-ion battery and charges with a micro USB.  Users can perform up to a couple hundred tests on one charge. BACtrack Vio uses 1 AAA battery for power, which powers the Vio for up to 60 tests.
BACtrack Mobile typically has a 25% faster warm up time compared to the Vio - the time between when you initiate a test and actually blow. In the just-launched version of the app (now available on iOS and coming to Android at the end of the month), we just added the “What’s Your BAC?” feature which prompts users to guess their BAC during this time.
BACtrack Mobile and Vio also use different sensor technologies. BACtrack Mobile employs BACtrack's police-grade Xtend® Fuel Cell Sensor Technology, whereas BACtrack Vio uses MicroCheck® sensor technology.  Here are the sensor technology differences:
  • A user can see slightly more consistent results with BACtrack Mobile.  For example, a user who is truly a 0.055% BAC and tests 3 times in a row with Mobile might see these results: 0.056, 0.057, 0.053% BAC. Typically results are within a +/- 0.005 %BAC range.  For BACtrack Vio, results are typically within a 0.010% BAC range. So in this example, the readings might be 0.050, 0.0.057, 0.060% BAC.
  • Because of BACtrack Mobile's Xtend Fuel Cell Sensor, BACtrack Mobile's results will be more consistent at higher BAC levels - 0.20 %BAC for example - as compared with BACtrack Vio.
  • BACtrack Mobile's solenoid air pump is also more likely to prevent user errors during the breath sampling process; it is also more likely to identify incomplete breath samples and require a retest, usually required for professional testing applications.
