My next update will get Adguard, Cleanbrowsing with all types of filters that they offer and both DoT and DoH (assuming apple is okay with it). It's not too bad when it comes to latency but they don't have servers here so anything that is outside the country won't be fun to use. But if anyone is using them in the country they have servers in it would be great to know how they work. Using root servers with pihole is usually best of both worlds when it comes to latency and privacy.

Edit: I made the app because I wanted a simple 30 second solution for anyone to improve their privacy without any VPN profiles and using a fast DNS. I tried a few free apps on the App Store but they didn't work well or were not updated in months. So I decided Ill make one.
