This app will keep you awake by making you press a RESET upon the desired seconds once you choose the seconds depending on how sleepy you are you press the start button when it reaches 3 seconds you will get warnings if you fail to press the RESET button the ALARM will sound until you press it then it starts all over again until you stop the app. If your family is in the car they will know if you failed to press the RESET button and take action.
Sleepiness causes auto crashes because it impairs performance and can ultimately lead to the inability to resist falling asleep at the wheel.
I made this application because I used to fall asleep with my family in the car. Believe me I know first hand the danger it poses.
