What made you want to make the switch? I’m currently on Mint

Gotcha, Adguard Pro on iOS doesn’t have a DNS limit but I suspect you are right and going over the free limit on NextDNS would be pretty hard to do one one device, especially a mobile device

You can point Adguard Pro and maybe even NextDNS to Mullvad’s DNS Server. So I wonder if doing that is better than using Mullvad’s DNS profile alone on an iOS device? Not sure, but Adguard Pro has a safari extension and more settings. So I wonder if doing that covers more?

Adguards privacy policy seems very good for Adguard Pro on iOS: https://adguard.com/en/privacy/ios.html

But I know that they originated in Russia and that gives some cause for concern. Their current HQ is in Cyprus
