Next time you find yourself in one of those situations, just run this app, enter the amount of options available to you, and press go.
The app chooses a random number from 1 to the maximum options that you have entered. And then displays it to you. Meaning you no longer have to choose for your self. Its like flipping a coin with more than 2 sides.
This app can also be used for things that require a random number. For example if you didn't have a dice for a game. Just enter six as the amount of options and then press go each time you want to role the dice. The app will then pick a random number out of six, just as a virtual dice would.
