SLS - Spirit Box: A revolutionary ghost detection tool designed for those interested in the paranormal field, this free app offers a unique experience with its advanced features.The standout feature of SLS - Spirit Box is its cutting-edge SLS camera. This tool transforms your device's camera into a ghost detector. It analyzes real-time images frame by frame, mapping human figures without the need for expensive equipment like a Kinect camera. While it aims to eliminate false positives, it may occasionally interpret non-human objects as human figures. It should not map when there is nobody in front of the camera but if something is mapped and there is nobody there this raises the intriguing possibility of detecting spirits or entities that are invisible to the naked eye. At least, that is the theory. You can choose to disable/enable an audible and visual warning when a presence is detected.
One of the app's additional features is an upgraded Spirit Box, derived from "The Machine ghost box." It scans reversed speech audio banks in real-time, creating human-like tones for manipulation. Notably, no pre-programmed words exist in any language. Users can adjust the scan speed from 100 to 1000 ms using plus/minus buttons, or opt for the auto button to randomly select scan speeds.
It's worth mentioning that this app utilizes high CPU usage due to real-time frame by frame analysis. For optimal performance, a powerful CPU is recommended. However, even on low-end devices, the SLS camera accurately pinpoints the location of detected presences, prioritizing precision over high frame rates.

This app is very useful 2-n-1 tool for speaking to Spirits and seeing that they are there. It's a spirit box, and a SLS camera. The downfall to this app is that it doesn't video record sessions or allow for use of the camera for still photo thru the app. You need to download a screen recorder with that records both internal and external audio, if there is not one pre-installed. It's not easy to take a screensot while using the app. Add the ability to record, video and audio. through the app!

I think this app, last updated in 2017, has potential. It's easy to use and works on my latest Samsung phone. I think it said "dead beat" referring to a guy that doesn't pay child support. I don't bother use the recording since I have a separate recorder.

I used to love this app. But now what's happening is I can not scan the room and see the SLS camera. It will not open. im kind of disappointed because I love playing with this app. So hopefully, maybe you can fix it. And I can get back to my ghost hunting. Thank you.

This app is very real.l and amazing. I've actually had full length conversations with a handful of my close friends who have recently passed on at the same time .I swear as God as my witness it was like a zoom call it blew me away I practically fell off the couch. Totally amazing app guys please keep doing whatever it is your doing because you've nail it on this one .personally I'd give it 10 stars if I could unbelievable .

it's got the longest sound snippets making it one of the most comprehensible Ghost Boxes i've used. i've had a 1201 error earlier when i tried to record. They spoke English, which is weird seeing that i live in Japan. i asked how many Spirits were here, '1,000' a male voice said. i did get a clear answer from a kid voice when i asked the Spirits to listen and identify what made a mystery sound i had caught on a voice recorder and i had uploaded videos with the mystery sounds played at various speeds and tempos. 'Aliens' the kid voice said. Great. You can't fight Aliens. it's not like they can be exorcised. i played a Taoist Onmiyoji giving an exorcism in Japanese and a Catholic Priest giving an exorcism in Latin for the Spirits. Nothing happened. Cool app. Thanks for making this app. Arigato.

Freshly downloaded and the camera doesn't work even though it is enabled in settings. Whatever the bottom button is = it's hidden by advertising. I played the video to be free of those adverts + it didn't go away. Sad times

The sls system does work and all but let's just talk about the spirit box for a second - we tried the Estes method with this app last night and we experienced the real deal and had a full conversation that was almost completely comprehensive. 10/10, my only complaint being the app is a little slow
