GlassWire

GlassWire is an app that lets you screen the behavior of the apps installed in your smartphone. Doing this will help you find out if they are reducing your connection’s speed or using more data than they should.

From GlassWire’s main page you can see a graph that describes the Internet consumption off all the apps in your smartphone. On the upper left corner you can change the timespan shown in the graph: from 5 minutes up to 90 days. Also, clicking on a specific app will show you its graph.

Another great feature of GlassWire is that all the information stays in your Android. In the app you can check that the information will never be sent anywhere, unlike most of the other apps in your smartphone.

GlassWire is an excellent tool to monitor your apps that offers you really useful features and an elegant and appealing interface.
