"Description
Adblock Fast is a free, open-source ad blocker!
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.

Adblock Fast app design - A
Even though Adblock Fast is a free content blocker, one can tell that the developers gave some thought to the design and layout of the app. The animation upon opening the app catches the eye. While the app only has one page, the developers have made it easy for the user to turn on and off ad-blocking by simply tapping the main app screen log once, as well as providing a contact help email address for Adblock Fast by pressing the "HELP" text on the app page. Pressing the "HELP" text also explains to the user in a succinct manner, how to enable the app in Safari.
Adblock Fast blocking power - A
Out of the free content blockers reviewed thus far, Adblock Fast has done the best job loading and rendering the test webpages. I can tell that the developers have done a lot more than cut and paste the json file into the app. Take note developers who have created content blockers. If you want to stand out, take heed. Anyone can cut and paste lists. And the results of several of my reviews lately show (in my opinion) that many have done just that. And that is one of the reasons why the same websites have the same problem in so many content blockers.
I liked what I saw.

Adblock Fast speed - A
I don't know about "the world's fastest," (as the app claims) but Adblock Fast is fast (at least in my experience). In my opinion, it is just as fast as Purify. It stands out in the app crowd.
Adblock price and developer contact - A
The A rating is solely based on the price of the app, (free) as I did not contact the developer and I do not know their customer service history.
Adblock Fast overall rating - A+
If you are looking for a free app that blocks ads, doesn't leave you waiting, and doesn't require tweaking, I recommend Adblock Fast.
In my opinion, the developers of Purify, Crystal, Admop and Silentium better stay on their proverbial code toes. With Adblock Fast available, said developers better give customers strong reasons to buy their app and stick with it.
I wish the app had Whitelisting ability and social widget blocking. Maybe if enough people request it, the fine folks at Rocketshipapps will incorporate the features in the next update.
