Ghost radar (joke)

幽霊を検出するためのレーダーの専門シミュレータを使用してください！

If you want to scare friend with horrible ghosts and zombies - use this app! It shows where are paranormal beings near you. Of course it's only a simulation, so it shows random images of ghosts and zombie. But you can say to friends that you feel that your home is haunted. Then show them this app to scare friends!
