Ads on a black screen
The showed images are either photoshopped or taken by a real night vision camera. In this app you stare to a black screen and the increase the contrast to the camera with a green filter. That’s it! You end with a green image that doesn’t show anything but noise. But that isn’t the worst part, every change you make within the app (increase contrast, change the camera, get back to the app,...) triggers an ad, that’s the real business here. Don’t waste your curiosity.
