The idea is great!
Honestly this app is really cool! I didn’t prank anybody and that’s because the home screen thing you start on is for the iPhone 6 Plus, 7 plus, or 8 plus. I’m using an 11 year old iPhone 5s! So sure, I can use a home screen photo from my library, but I’m to lazy to, like everybody today. Another reason I didn’t prank anyone is because the cracks just aren’t realistic, especially on older iPhones with lower resolutions, like my iPhone 5s. However, I do love the app because everything is mostly free that I’m aware of, so good marketing, developers!
