Connection Tracker allows you to monitor the data usage of all the applications and services running on your Android device, even in the background.

This program works by keeping a tab on all the network connections, and monitors all the data traffic, as well as the local and remote IP addresses, city, country, and company information.

You can also get notifications when a connection is made. It also gives you the option to view all the applications and services currently using the network, as well as the amount of data they are sending out.

It is a very useful tool for people who want to monitor the usage of their applications and services.
