iBAC - Check your blood alcohol content on your iPhone at App Store analyse

This app turns your iPhone into a breathalyzer. You can determine your blood alcohol content by blowing into the device, just as you do with a real breathalyzer. Of course, the resulting value does not reflect the real blood alcohol content of your breath since it can be influenced by whether you blow evenly and move the iPhone during the test. In some situations, you obtain results which really do correspond to the actual blood alcohol percentage.

One special feature enables you to post the result to your facebook profile so that you can keep your friends up to date on your current state or your party spirit.

DISCLAIMER!: The BAC calculation is an approximation *only* and is affected by a number of factors that can vary from individual to individual. Always drink responsibly and never drink and drive.
