If you like this kind of thing …
I'm sorting through my apps because they were all dumped onto my iPad when I set it up and I don't know what they all are. This looks usable and cheap at $2 for 60 masks, at least that's the price today. The masks- although that seems like the wrong word- are more attractive than some others I have. I tend to not use this type of thing but I can see the value.
I got 3 masks for free and then was asked to pay. It's kind of useless with only 3 but for the price I think I'll keep it in my Photo Tools folder and see if I use it.
