This is a most excellent place for technology news and articles.
Yeah, and currently you don't need to know what an apk is to install them.
Then you're just installing from the play store are you not? If you want to use f-droid or something else you initially have to start with getting their .apk do you not? Or am I mistaken and misremembering?
