AdGuard is a content blocker for iOS that lets people block trackers and ads in Safari. Its AdGuard Pro app eventually got pulled from the App Store because of new VPN rules. AdGuard 3 brings some of those Pro features to the regular app, and some of them are locked behind a premium subscription. But Pro users can get a free 6-month license key. AdGuard 3 fixes a key issue with Safari. Safari’s maximum limit for content blockers is 50,000 rules. AdGuard now works around this by combining five blocks into one, each separately enabled in Settings and each with 50,000 rules. It also supports DNS-over-TLS and DNS-over-HTTPS.
