Ghost Radar® is the original application designed to detect paranormal activity. Ghost Radar® attempts to detect paranormal activity by making various readings on the device. Traditional paranormal equipment can be easily fooled when simple mundane bursts of normal energy occur. Ghost Radar® sets itself apart by analyzing the readings and giving indications only when interesting patterns in the readings have been made. Please note we offer no guarantees of accuracy or any warranties, therefore, since results from this application cannot be verified scientifically the app should be used for entertainment purposes.
Ghost SLS

For our Ghost Hunter friends this tool will allow you to use your Apple device to scan for human figures. Ghost SLS works as an SLS Emulator to so you can get results without buying an expensive camera. The camera filters allow you to determine if the figure detected could be due to the lighting conditions of the area so you can spot false positives. Because this is not a true SLS camera your results in low light may be less reliable. Because of this it is recommended that you turn on your camera's torch light if you are scanning in dark areas. You can also snap photos of what you catch to share with your friends or other investigators. Join our group chat to discuss ghostly things with other users. If things get a little spooky we recommend turning on some lights and taking a break from the app for a while. :)
