Network Log monitors iptables-logging to display a real-time list of which apps are making network connections, and provides statistics about those app connections.

The log tab shows the network packets being transmitted and their details such as:

• source and destination addresses/ports
• network protocol and interface
• bytes transmitted
• timestamp

The applications tab lists installed applications along with network usage statistics such as:

• total packets and bytes sent
• active network throughput speed in Bps/Kbps/Mbps
• timestamp of last connection
• list of all the unique connections made by each app
• sortable and filterable

The statusbar icon's up/down arrows will highlight when upload/download traffic occurs, and the notification drop-down shade displays the connection throughput speed in Kbps.

You can also configure toast pop-up notifications on a per-app basis that will pop-up a temporary notification containing connection details no matter which app you are in.

Click an app in either tab to see time-lines of its connections.

Select the 'Apps Timeline' menu item to see an over-all time-line of all apps.

Adjustable interval from 1 ms to 48 hours for summing data:

• to see each packet, set to 1 ms
• for Kbps, set to 1 second
• for Kb-per-hour, set to 1 hour; etc

Adjustable pinch-zoomable and scrollable graphs.

Requires rooted devices.

Note: While the app itself is designed to use minimal CPU/battery, you can further reduce the CPU/battery use by exiting the app after starting the logging service.
