This app is intended for entertainment purposes only and does not provide real “paranormal activity” or “ghost locating” functionality. Ghost Detector - Lost Souls detects possible signs of paranormal activity around you. Using advanced algorithms, the app analyzes electromagnetic fields, temperature changes, vibrations, and sounds to interpret possible nearby presences. For the best experience, use it in a low-light environment with as little noise as possible. Note: during development, strange events occurred. Random-looking code fragments appeared to connect into unexpected protocols; during tests, noises were heard and objects seemed to move. Good luck!
Ghost SLS
This app emulates an SLS camera to detect human figures using your device's camera. It includes filters to help distinguish real detections from false positives caused by lighting. Users can capture and share photos of their findings and connect with others in a community chat.
- SLS camera emulation
- Human figure detection
- Camera filters for false positives
- Photo capture and sharing
- Community group chat

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. :)
