Armed with the power of Xtend™ Fuel Cell Sensor technology, the BACtrack breathalyzer uses the same technology used by professional groups around the world. Quickly test and view BAC results, and read safety information about corresponding impairment levels. With ZeroLine™, a revolutionary new feature that estimates your decrease in BAC over time, the app estimates when your BAC will return to 0.000%. Saved BAC readings are automatically mapped on the Tracking Graph, allowing you to get a clear picture of your drinking habits and gain insight about how your body processes alcohol. Track what you drank and where with photos, notes, and drink logs. Your BAC results remain private, or choose to share via text message, Facebook, Twitter, etc.
