Awful. Please read for an actual review.
The app follows the trend of allowing you to download it, use it right up until you try to save an image then tells you to rate the app 5 stars before you can continue. Evidently, you can get away with 1 star. Which is what this deserves.
You get an ad pop up anytime you literally do anything. There's no explanation as far as which image's face is swapped onto which body. Unless the pictures are perfectly symmetrical like in the advertisements, the results are pretty horrid. And there's no easy way to edit.
Correction, there isn't a way to edit. Basically look at 10 different ads for awful freemium games, then if you don't like how your image came out? Start over from the beginning.
Really. Like the high score is misleading. This is a terrible terrible app.
