Doesnt work

I dont understand any of the good reviews. I cant get it to work. I tap the screen, the shutter clicks once or three times, then it says "please waiting align..." for about a minute (a minute between pictures, really?) Then, if it doesnt crash, it goes back to my picture (one picture, not a split screen). But there are no controls, no way to edit or do anything but exit the app. The picture does not save to camera roll, so I have nothing. Its not just useless, its unusable. Btw, I use avgnite cam. It works.
