Earlier quoted context omitted.
Dang, you're right, I forgot about that. So not so suitable, unfortunately. Seems like root + a local hosts adblocker is still the best solution for Android, or a local VPN for iOS (do they have those on Android? never checked).
> or a local VPN for iOS (do they have those on Android? never checked). It seems so; at least my Android phone has something named "VPN", which I sometimes use to capture traffic and look at what my phone is sending/receiving. (Packet-capturing your phone traffic is a pretty eye-opening experience; I was surprised just how much data about you goes to ad/tracking services.)
for iOS (for jailbroken) via Cydia and BigBoss I am using "Firewall IP7" which is not yet updated for iOS10, costs $2.99 or near
both act as firewalls in learning mode.. it can be a little tedious in the beginning but as soon as you block most ads/trackers/beacons "globally" then you feel the difference on speed, bandwidth usage, and user experience
