Mobile browsing on iPhone often feels cluttered and slow. I want a Safari content blocker that filters known ads and trackers so pages load faster and feel more private. The companion iOS app (built with UIKit in MVC) should make it simple to turn the blocker on or off, add sites I want to support to a whitelist, and view lightweight stats about blocking. The rules must stay effective by automatically fetching and applying updated blocklists from our server on a regular schedule, using Safari’s content‑blocking ruleset to block network requests.
