☆ Block Internet access for any apps:
One can select to block a selected application or applications, application running as root. Since it blocks Internet access per application ID (UID in regular Linux
system), several applications may be assigned the same ID, you should block all of them or nothing.
☆ Separate 3G and WiFi data
For each application, you can select to block Internet access via either 3G or WiFi channel. It’ s extremely helpful if you don’t have an unlimited data plan. It saves you
from over-billing because of background application accessing Internet such as Google+, Google Play or Amazon Music.
☆ One-click widget enabled
One-click widget is the easiest way to toggle blocking status. It’s useful when you don’t want to use data connection and occasionally turn it on for a while.
☆ Test blocked app in a touch
Once you block an app, tap on it to see if the application can access to Internet or not.
