I paid the 99 cents for the create your own feature and with the thought of ads being disabled but nope. You cannot edit or go back or retry a pic without being constantly raped by ads, some forcing you to watch or wait 5 seconds of video before allowing you to skip.
Also while recording what looks to be a perfect fit or match seems to change after saving and your mouth being half cropped out. Another problem I've experienced is in the gallery. I'll try and load up one of my creations just for it to freeze, I'll back out and load another just to the last pop up instead and still froze. Even if you delete it's still what comes up. This app has very amusing potential. I'm using an IPad Air 2 btw.
