Don’t worry! Your results are as private as you want them to be. All sharing default settings are off so you have complete control over who you spend the night with.
The minimalistic design ensures you can take the Vio everywhere. It comes with a keychain, and the mouthpiece discretely folds into the main white compartment. The device measures 0.5 inches by 1 inch by 2.8 inches. To the untrained eyes, it might just be a sleek remote car key.

Operating on one AAA battery, this Keychain Breathalyzer yields accurate BAC results every time in just seconds. BACtrack is the #1 most-trusted brand of breathalyzers, and with 13 years of experience, nothing less than high accuracy and dependability will do. Using ZeroLine technology, the app predicts when you’ll be at 0.00% BAC so you can make safe transportation decisions.

Bonus feature: You can guess you BAC before you test yourself so you’ll have a clear idea of how every drink affects you.
If you want to make better decisions, get the Vio and charge safely into the night!
