Now I couldn’t get into this app maybe Stereogram isn’t for me but let me tell you a bit about how 3D stereogram Human works , this application is made ​​to the point that it is possible to enjoy a three-dimensional feeling of real completely, different from other stereograms.So you might be saying What is a stereogram app? well by intentionally focusing on something with your eyes, pictures will become 3D. Now I do agree that you have to be 17 to download this app since some of the pictures aren’t for young kids some of the features of this app include Brightness adjustment,Reduction and expansion function of pictures by pinch in and pinch out. You can view the app in all pictures,  parallel method,cross-eyed method,answer pictures there’s also a bookmark function and  slide show function with full screen. This app is developed by the same developer as the Sleep app  Overall I can’t see the purpose in this app from my point of view
