The Ghost Detector app is designed to detect ghosts, spirits, and other paranormal entities using various sensors. The sensors used for this purpose are quite sensitive and can be affected by many other things besides ghosts. For this reason, the app also includes a built-in camera that you can use to take pictures of any paranormal activity. The pictures you take will then be analyzed and the results will be presented to you. 

The Ghost Detector app is also equipped with an EMF detector and a ghost-finding camera. The EMF detector is used to find any electrical fields and the camera is used to capture any paranormal activity.
