Crimson Team is offering Decision Maker over at the Windows Phone Marketplace that may help you get past those hard decisions.
It's a simple process. Think of your question, tap the "Make Decision" bar, and Decision Maker will offer a yes or no response after consulting with aliens, Santa, Granny and many more reliable sources.
Decision Maker is a simple, stable novelty app for your Windows Phone. The $.99 price is just about right for a novelty app and there is a trial version available if you need a little help in deciding to purchase or not.
You can find Decision Maker here (opens your Zune desktop) and if you follow the break, you can catch a video of Decision Maker in action.
