If you don't feel like enabling superuser (root) on the devices you own for system-wide ad blocking, Firefox for Android lets you install AdBlock Plus/Edge/etc. like any other extension and works quite well in my experience. When they stopped allowing those addons in mobile Chrome I started using mobile Firefox as my main browser and have been perfectly satisfied.
But yeah, if you don't mind setting it up so you can grant superuser permissions to something like Adfree Android, you get system-wide ad blocking which also gets rid of ads in most apps. Still, I haven't bothered in a while because good apps don't include really obnoxious ads and the good ones that offer free versions with unobtrusive ads deserve to make some money. If they're truly good apps, then I sorta feel bad when I don't even notice I'm using the free version because ads are blocked. There are a handful of apps where I fired them up on a new device before setting up Adfree and was reminded that I really ought to just shell out the $2-3 for the full version.
