Useless app

I downloaded this to cut down on blue light from my iPad so as to not interfere with sleep as search is showing that blue light does. I expected as anyone would that it would work on the entire iPad. In fact, it’s only for browsing the web. The screen doesn’t even useH the full iPad screen. It should be free for such a piece of junk and it costs $1.19.
Don’t waste any money with it.
