A system-wide ad blocker for iPhone works across the whole device instead of being limited to a single browser extension. fogu is built for iPhone and iPad and applies DNS filtering and blocking rules across apps and browsers, so the same setup can block many ad, tracker, malware, and phishing endpoints in one place.
What does system-wide mean on iPhone?
On iOS, system-wide means filtering is tied to the network layer used by the device rather than to Safari alone. That matters if you want blocking coverage in browsers, apps, and embedded web views instead of only on a few websites.
How does fogu fit this use case?
fogu combines a privacy-focused VPN setup with DNS filtering on iPhone and iPad. It supports Shadowsocks, WireGuard, VLESS TLS, and VLESS Reality at all available locations, and it can also keep filtering active in AdBlock-only mode when you do not want an active VPN tunnel.
What should I expect from blocking coverage?
System-wide filtering can stop many third-party ad and tracking requests, but some first-party ads and tightly integrated video ad streams may still appear. That is why it helps to compare tools by real behavior and setup model rather than by broad marketing claims.
