App doesn't work – Mega Sound SFX - Free, Funny, Original, Loud Sounds, Animals, Pranks, Guns, Jokes, Fun and Derpy Effects! Review

I downloaded this app and it doesn't. Work on my iPhone 7. Then something popped up for a purchase. If I get billed for anything on this app I will contest it with Apple. I am not paying a dime for an app that doesn't work. I think they trick u into pushing a button so you have to pay. Stay clear from this app!!!!!
