Wonderful free firewall. Works very similar to Zonealarm for the desktop, which I have had running for over 2 decades. This is the one piece I have been missing for my android devices. If you can control what communicates to the rest of the world then the device will be a lot more secure. I have installed software on my PC before that shouldn't have required to communicate with the internet but was asking for permission. I would deny them and then uninstall the software.

I love this app but its "smart" feature is causing problems. Over time it blocks addresses even though you allow that same address. Block others and it allows them. Once you run into a situation where it blocks addresses you specifically allowed the only fix is uninstall and start over. Block something 20 times does not mean I wont have to allow it for one app. The decision should be mine over what gets blocked and not this app

I like this app it works well is easy on the eye and has plenty of options... but I do feel that a help section explaining them would be extremely useful (Not all users are tech savvy) All in all it works and does it's job... no ads and it's free so no complaints from me... You have nothing to lose by installing the app and you can feel safe in the knowledge that your phone is protected and safe. Thank you devs for all the work you have put into the app... well done
