So I prefer to use a DNS blocker (DoH) on my IOS devices to block ads, malware, and trackers. For the longest time I’ve been using Aha DNS Blitz because it allows you to choose the exact filter lists you want to enable. Recently I saw Mullvad now has their own DoH service as well and I’m trying it out now. It’s not as customizable as you can only choose a combination of the general categories (ads, malware, tracking, social, gambling, etc.). On the other hand, Mullvad runs everything on RAM now and they are very transparent of their methods and have a proven track record.

I’d like to get the community’s opinion on which of the two you prefer and why.
