I've been on Android for a decade as well but just got an iPad mini. The one thing I still cannot figure out how to do on iOS is block ads at the system level. Android has lots of apps that act as a VPN that block ads/trackers via DNS. It blocks ads in the browser, but also in apps.

I can't find the equivalent on iOS. All my searches lead to ad blockers using Safari's content blocking, but the VPN-style ad blockers appear to violate Apple's terms, and so aren't in the app store. I've also seen recommendations to use Pi hole on my network, which is fine until I leave the house.

If anyone has recommendations for system-wide VPN/DNS-based blockers for iOS, please share. That's the last real thing keeping me on Android.
