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. :)
