Are You a Good Thief? 
Do you think you have the thief skills to take anything without someone noticing?

SEE WHO CAN MOVE THE FURTHEST
Are You a Good Thief? tests your abilities to move your iPhone or iPod touch without disturbing the sleeping person. The faster you are at moving it without waking the sleeping victim the better you are!

RACE YOUR FRIENDS - SEE WHO'S FASTER
Try racing your friends to see who can move the sleeping person the furthest in the shortest time period. The game even will save your highest record for the longest time without waking them!

Think of it like a thief game, almost as if you were playing truth or dare and you got dared to take the phone without anyone noticing. How far can you steal an iPhone or iPod touch without triggering any of the accelerometer sensors? If you get really good, see how fast you can move to a checkpoint before the sensors trigger. If you're not really that good, just slowly creep around the house with a snoring device. That's right, it actually snores as you're moving it. If you move it too fast though, you'll hear them wake up. Great game for children and fun entertainment to watch others creeping around at a party with your phone or iPod trying not to trigger it. Think of it like a great party game, like Truth or Dare with a live action twist to it.
