NetGuard is an application developed to provide a way for blocking other apps from accessing the Internet on your Android device. The nice thing about this app is that you can install it and use it without having to root your smartphone or tablet. This is a great plus besides the intuitive layout used inside the interface. Here you will find a list containing all of your installed applications and video games.
By blocking access to the Internet you will free up some data usage and even save battery life. After you tap on a installed app you will see additional information such as package name, version, download and upload rate and more. NetGuard allows you to change rules for individual applications and improve your privacy by blocking them from sending information to home servers.
This tool has support for TCP/UDP, IPv4/IPv6 and even for tethering. There are many symbols used by this application and you can find the Legend sections which explains each icon used inside the interface. Furthermore, NetGuard provides a separate section where you can see the traffic and actions log and you can use it to check if the tool does its job or not.
