An alcohol checking program promises users to tip them before they get in serious trouble.

Tester response
An iPhone alcohol checking application dare promise that it may help to reduce the fatal consequences of drinking too much alcohol intake. Specifically, the program can test his own party’s response capabilities, logic and coordination skills, and thus judge whether he is able to drive home. Therefore, the program has also been named: ‘Fit to Drive’.
The program can also give an indication of when the user is again able to drive. But the purpose of the many tests in the program is primarily to raise awareness about dangers of drunk driving.
The program is made by Danish Designit in cooperation with the Medicus Engineering. It is free to download the program until the New Year.
