If you've ever wanted to get on TV Shows such as Ghost Hunters, then Ghost Prank is the app you need. Ghost Prank automatically superimposes a picture of a dodgy ghostly figure on your images. Sounds pretty bad? It generally is and it's hard to work out whether this is a parody app or a serious attempt at creating possible ghost sightings. However, if you just want to get a few cheap giggles on Facebook or Twitter, then Ghost Prank can instantly publish your creations online.
