There are more than half a million apps in Apple's App Store. Some are stunning achievements. Others are not.

Below is a video demonstration of the app Airplane. Touch the "Take Off" button to hear the sound of an airplane engine. Shake the phone to hear a flight attended tell you to put your seatbelt on. That's it.

We leave you with this free app from the "Entertainment" category (that's a stretch) and a hearty "no comment."
