iOS users have plenty of options here too

• AdGuard Pro (paid)
• AdGuard DNS (free)
• other free dns blockers - NextDNS, ControlID etc
• Safari addons
• browsers with blocking built in (eg brave)
• VPNs with ad blockers built in

DNS and VPN blocks will work on most apps and all browsers.

I prefer Asguard dns and then Safari extension or Brave
