Works great to block ads, and other things. Is not a Firewall to fully block the internet access of the apps,it will block connections of the apps that are part of the filter list... it has a huge list of sites/domains that are know to show ads.Example, even it you pick Edge to protect it, it will not block the internet access, but it will block a lot of ads, dangerous sites,XXX/explicit content and more. Is free and seems to be secure.I will test it more. Don't give a bad rating without testing

Confusing. I could not find a way to control individual apps. It offers me to "protect" apps, but I could not find out what that is even supposed to mean. One can supposedly block types of data (e.g. adult content), but the lack of obvious fine control makes this one hard to recommend. It did not notify me of a new app wanting to go online or block anything I would have noticed.

If there were a feature that detects when a phone call is being made and disables the internal vpn/firewall that would be great because it literally breaks my wifi calling half the time and it's very frustrating having to disable the app everytime I want to use wifi calling...
