This is still available on iOS, amongst others:

Of course, the limits on installing software on one's own device are still a concern.

That article appears to be somewhat out of date; Adguard Pro is still available:

It is, but system-wide ad blocking is disabled by default. You need to manually add filters subscriptions or hosts files in order to get it back. Not that it's much of a problem, though.

Does adding said hosts files require a jailbroken device or are the files added in the app?

[gvurrdon]

The files are added in the app - it seems to work well, though I’ve seen reviews suggesting that some users have been confused by it.
