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. :)

Verdict
The clearest difference is price: NightVision at Free against Ghost SLS's $0.99. NightVision also leads on review sentiment (50% vs 37%). Ghost SLS's advantage is rating (4.4 vs 3.8) and update cadence (every 2 months vs every 16 months). On ads, in-app purchases, monetization model and device support there is nothing between them.

NightVision is free to download; Ghost SLS costs $0.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Ghost SLS holds the better App Store score, 4.4 against 3.8. That said, the two scores are not equally well evidenced: Ghost SLS has 3.6K ratings behind it against 19, so its average is the more settled of the two. Written reviews complicate that: 50% of NightVision'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.
NightVision ships an update every 16 months, Ghost SLS every 2 months. The most recent releases landed on October 1, 2026 and October 14, 2026 respectively.
