This is the best app I have ever seen in my whole life!!! If you do not know how to view the 3D image, it can be very frustrating!(You are not alone, I couldnt see it at first either!)This is a quick tutorial on how to view the image...First, move the device about ten inches away from your face, next blur/squint your eyes so that you can still see the screen, focus on the middle of the screen (This is where the picture will show up), after that adjust your eyes and move the screen toward you and away from you until you can see it!!! I hope this review helped!!!!!!!!!
