Blood Alcohol Content Calculator

When you first launch ENDUI on your iPhone or iPad, you will be asked to enter your gender and weight. Furthermore, you can input the kind of drinks you've had through the night, along with the duration over which you've had these drinks.

This app will then automatically estimate your blood alcohol level so you can determine whether it's save for you to get behind the wheel. Considering the large number of accidents that occur due to drunk driving, this app truly has the potential to save lives!

Other Features

There are plenty of other functions and features in this app. You can use the "Report a drunk driver" option, which will immediately call 911, allowing you to report any sightings of drunk driving.

If you find that you are over the limit for driving, you can also call a designated driver, whose number you can input easily prior to heading out on the town. You can also call a cab through this app.

There are two games that simulate driving, and test your reflexes and memory, allowing you to further determine whether you should be driving.
