$4 a week for wallpaper?

I downloaded the app and started it. First thing, it offers a free "premium" trial for $4 a week. It says you can cancel at any time but otherwise it will automatically renew. No option to decline the "free trial". They obviously are hoping you will forget to cancel. App may be good- I dont know. They dont let you even find out without subjecting you to predatory sales practises. No thanks.
