Adblock Fast is a new, faster ad blocker and the first open-source ad blocker for iOS (http://appadvice.com/appnn/2015/09/adblock-fast-is-a-free-and-open-source-way-to-banish-ads-in-ios-9)! Just as webpages grew bloated with ads, so too have ad blockers grown bloated with little-used filtering rules and features that sap their speed and hog your device’s disk space, CPU cycles, and memory. Adblock Fast runs an optimized ruleset to accelerate pages more but consume less system resources than other ad blockers do. Adblock Fast blocks ads in Safari not in other apps. To allow Adblock Fast to block in Safari: 1. press the Home button on your iPhone or iPad, 2. tap the “Settings” app, 3. tap “Safari” > (under “ General”) “Content Blockers”, then 4. toggle the “Adblock Fast” switch on. To unblock ads, navigate to the “Adblock Fast” app. To see the effect of Adblock Fast on a particular page, you may have to clear Safari’s cache (tap “Settings” > “Safari” > “Clear History and Website Data”) before reloading the page.

SafaShield is a Safari content blocker app developed by NoVirusThanks Company Srl that was created to improve Safari web browsing security by blocking potentially suspicious and malicious domains. We provide built-in options to block most abused TLDs (such as domains that end in .top or .xyz), dynamic DNS domains, free hosting domains, internationalized domains, unsecure connections, and more. We added also options to protect the user's privacy by blocking ads and web trackers. Other useful features you can find aboard are the possibility to whitelist a domain so it will never be blocked, allow ads on websites you trust and that you visit frequently to support their work, block custom domain names and also custom domain TLDs (such as .it or .info). The main focus of this app is to reduce the attack surface by improving the Safari web browsing security with smart content blocking rules.
