Adblock is an iPhone, iPad and iPod Touch app, which lets you block certain domain names that, for example, serve advertisements.
AdBlock uses iOS VPN OnDemand feature. It installs a dummy VPN profile with predefined list of domains. Every time some app tries to communicate with one of the domains, it will try to connect via a non existing VPN server. This will also result in ads being blocked in different apps.
Install and open AdBlock app, swipe up the orange box from the bottom of the screen, Install dummy VPN Profile and your AdBlock is enabled. Don't forget to open AdBlock app once in a while to check if there were any changes in AdBlock's VPN profile.
This is normal. You can't connect to it, because this is a dummy VPN server. If you can't do it, the apps and websites won't be able to either - this will result in ads being blocked. Apps and websites will try to use this VPN server only for domain names from our predefined list.
VPN icon appears only when you have successfully connected to a VPN server. Because AdBlock installed a dummy VPN server address, iOS won't be able to connect to it so there will be no VPN icon.
AdBlock does not affect the security of your connections in any way. It DOES NOT act as a VPN server and we DO NOT receive any of your traffic. Adblock block ads, because your device will try to connect through local IP (on your iDevice). Because there is no VPN server there to pass this connection, the ad is not being downloaded. Everything is done on your iDevice.
Yes. Once AdBlock's VPN profile is installed it is able to block ads while you use your iDevice on WiFi or GPRS/EDGE/3G/LTE networks - there is no need to setup it again. It just works.
There are 2 ways to disable AdBlock: 1. Open AdBlock app and slide down green box to install new profile that disables AdBlock. 2. Alternatively, you can quickly disable AdBlock by going to Settings app -> General -> VPN -> tap blue (i) icon next to "AdBlock dummy VPN". Disabling "Connect On Demand" will disable Adblock's functionality. We encourage our users to use second method, as it is much quicker.
WARNING: Latest YouTube app update use different mechanism to get ads. This caused Adblock to be ineffective against ads in YouTube app. We're currently working on a solution to this problem. For now we encourage our users to use great YouTube alternatives for ad-free experience: Youtube site in Safari web browser or alternative apps like Tubex or Tubee for YouTube.
Unfortunately, no. Recent Chrome build on iOS has a bug that causes Chrome not to use VPN onDemand feature of iOS. We have alerted Google about this bug and wait for a fix.
