AdGuard Pro can do DNS blocking on iOS. The default AdGuard server selection will block tracking requests.
If you only want to block malware, or other more serious badness, you can opt for others servers such as Quad9 or OpenDNS .
Edit: AdGuard is also (partially?) opensource - https://github.com/AdguardTeam
The apps aren't even using their own bandwidth. This is a disgrace that Apple is allowing this and doesn't provide a control to monitor or stop it.
