Use it for both mine and my wife’s iPhones. ### 4/5 — Needs System-Wide Security Profile *2019-05-18, version 3.2.0* Please make a VPN profile for this! That should especially take care of Google ads across apps other than Safari!

No ads sneak through ever, unlike with competitors I've tried. Oh, and a tip. If your content won't load because the page you're accessing is detecting the blocker and preventing access (e.g. Forbes), select the up-arrow-from-a-box icon and choose "Request Desktop Site" on the far right of the bottom row of options. Works in most cases. :) Great app! ## Frequently asked questions about Just Content Mobile Security ### Does Just Content Mobile Security have ads?
