When used correctly, this application can track your BAC level over the course of an evening, whether you’re drinking pints of beer, small glasses of wine or double martinis! Simply enter your drinks as you consume them, and based on your weight and gender the chart will tell you when you will return to under .08% blood alcohol level! Developed by well-known DUI lawyer James C. Egan of Seattle, Washington, this app is a lifesaver for avoiding per se DUI in any state. Other great features of the app: Bartender Ninja sobriety game (break those bottles!), text of the popular article “What you should know before being stopped for DUI,” by James Egan, an easy way to record an officer’s conversation (legal to do in Washington State!), and an easy way to call or text messages to James Egan personally, and set up a Skype/ Facetime consultation. Best of all, it’s perfectly free!”

This app is provided as a resource by The Law Offices of James C. Egan PLLC, includes James C. Egan, a former prosecutor and public defender, Karl J. Verzani, Jay W. Wilkinson and Lynda J. Stone, experienced criminal trial attorneys. You will find us in downtown Seattle in the heart of historical Pioneer Square at First Avenue and Yesler Way.

Love the information


My only question about the DUI information is "Are all the procedures of the police officers and legal restrictions the same in different states?" I'm from Illinois and I am hoping these tips will help me if I get in a similar situation. Thanks again

Excellent app with excellent information.


Lots of accurate and very useful info within the FAQ section. BAC calculator seems as though it works fairly well but would not trust my foreseeable future to it. All in all good app.

Nice app


Really cool. One good feature would be a landscape view for a longer chart
