SLS - Spirit Box offers a unique experience for those interested in the paranormal field. The app features a cutting-edge SLS camera that transforms your device's camera into a ghost detector, mapping human figures in real time without the need for expensive equipment like a Kinect camera. While striving to avoid false positives, it may occasionally interpret non-human objects as human figures, potentially detecting invisible spirits or entities.

The app also includes an upgraded Spirit Box that scans reversed speech audio banks in real time, creating human-like tones for manipulation. Users can adjust scan speeds and enable warnings when a presence is detected, providing a comprehensive paranormal investigation tool.
