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. :)

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Ghost Radar® sells 4 one-off in-app purchases. Ghost SLS asks for nothing beyond the download.
Ghost SLS holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: Ghost SLS has 3.6K ratings behind it against 655, so its average is the more settled of the two. Written reviews complicate that: 60% of Ghost Radar®'s written reviews are positive against 37% of Ghost SLS's, so the app with the better star average is not the one people write more warmly about.
Ghost Radar® ships an update every 3 months, Ghost SLS every 2 months. The most recent releases landed on October 18, 2026 and October 19, 2026 respectively.
