☆ 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.

☆ 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.
