10 Best Firewall Apps for Android

A firewall app on your Android device translates to efficient data usage and less time complicating your life using the method. Sometimes you have so many apps on your Android, and you’re strapped for time. If you are free, yes you could access ‘Settings’ and just go to Data Usage to select ‘Restrict App Background Data.’ However, if you run the app, it will use internet data. There’s also the problem of not being able to select apps individually or view network traffic and data usage statistics. This is where firewall apps shine.

Plus, you also get additional features which your Android device won’t provide when you use these apps. Don’t believe us? Just try them out and be ready to be mindblown. Some are free, some are premium, and we’ve included something for all types of users and preferences.

Here is a list of the best firewall apps for android geared towards users of both rooted and unrooted devices.

If you’re looking for a free firewall for Android that doesn’t compromise user experience, NoRoot Firewall is your answer. We like NoRoot Firewall because it lets you block access to internet and mobile data by allowing you to shortlist your apps. There are additional features like being able to block specific websites and IP Address. The bad news is that it doesn’t work for IPv6 addresses (yet) which means it could not work on LTE connections.
