You can adblock at the DNS level using the AdGuard DNS plug-in for iOS. Not an app: it’s a system plug-in - https://adguard.com/en/blog/encrypted-dns-ios-14.html. It’s extremely effective across all apps that use third-party supplied ads. The only apps it cannot adblock on are those who serve up ads from the same source as their content, such as Pinterest and YouTube.
