3/29/16 Update 4.3.1 works and fixes the issues from Version 4.3. Blocks ads when on WiFi.
3/23/16 Update. Version 4.3 update does not work. When you try to Enable Weblock, it says needs to be connected to Internet. My phone is connected so deleted and reinstalled 4.2.2 which still works. Will wait for next update.

I was hesitant at first because of the one star Most Recent ratings. But when I visited their website and went to FAQ, I noticed they provided updated info so I gave it a try. It works and blocks ads on Safari and my favorite apps! It does take a few minutes to set up as you need to select all Adservers, etc, but to me, it was all worth it. I suggest once you install it, click the top Menu on the left corner of the app and go to Setup. Also go to their website FAQ section on how to setup Weblock for additional instructions. Once you have the first WIFI connection figured out, you can pretty much easily add other WIFIs when you connect.
