I don't know what all the good reviews are about, they must be fake reviews, because this app does not do anything. All you can do, is take a picture (which, why bother, smartphones already have a camera), or use a filter that changes the colors of everything. While pretty, that's not exactly a useful function. I have no idea what the other filters do, because you have to pay for them, and since there isn't a free trial or anything, I'm not going to waste my money on something that probably doesn't do anything it says it does. Don't bother.
