It’d be a damn shame if you accidently downloaded cloudstream, an android app that allows you to download and watch offline, or just stream nearly any show or movie. I wouldn’t recommend the super stream source, as it almost always has a version available. Also, just in case, maybe don’t download tachiyomi to allow you to read any comics, manga, or graphic novels you want. It also has shitloads of hentai and pulls from almost every website imaginable.

And avoid Anna’s archive, as it has tons of ebooks which might(I’m not a lawyer) actually just be legal?
