The Tracking Graph

Expanded Results Screen

With ZeroLine®, you can view an estimate of when your BAC will return to 0.00% based on your current result.

Categorize your BAC result as “verified” by answering whether or not you waited 15 minutes before testing (which affects the accuracy of the reading). Your answer will affect how your BAC result is displayed on the Tracking Graph.
