Omniscient is the perfect application for playing jokes on all of your friends. With a fresh interface, this application offers the perfect way to freak your friends out.
Here's how it works: To begin, you type in the answer to the question. As you do this, "Please Answer:" will appear so the person you are fooling doesn't see the answer. After the answer, type an "x" followed by the actual question for the answer. The question will appear in the question area as you type. When you are done typing it, simply hit "Answer" to show your friend the answer and fool them!
Due to the way it was created, it can answer any and every single question you ask it (provided that you yourself know the answer). Your friends will think your iPhone knows everything, it's perfect!
