Not long ago, alternative DNS service 18.104.22.168 was piled up in Cloudflare. Relatively complex structures (as described here) should focus on privacy and speed. Cloudflare looks like this. Among other things, there may not be a provider who can see the pages surfed by the visitor, so there may be black sheep that sells her browsing history.
We've released free apps for iOS and Android to make it easier for mobile users. It should change the DNS, start the application, and simplify the click-completion process. However, because everything is realized on iOS through a VPN company profile, other VPN solutions may not work in parallel.
