Become transparent app

So I saw this cool app about taking a pic of yourself and making you invisible, so I bought it for $0.99, and guess what......IT DOESNT WORK!!!
I demand a refund! When I try to open it up, it shuts down on me right away. So why doesnt it work?
For now its gotta be 1 star because it doesnt work.....when it starts to work again, I put it to 5 stars
