We’ve all heard the sickening sound of bones breaking, now you can make them splinter and crack before your very eyes. Whether you find this app disturbing, calming or a little of both, we think you’ll agree there is something oddly addictive about breaking bones.

Tap on different areas of the hand to watch the bones break and shake the phone to heal. XRay Crack-Up is sure to make you do just that!
