I have used several apps for green screen videos on the iPad, and this one is definitely the best. It is very forgiving with wrinkles and shadows on your green screen, and makes it easy to create videos which look professional. Last year my fourth and fifth graders created hundreds of green screen videos with this app, and they loved it. If you are going to buy a Green Screen app on your iPad, this is the one to get!
