Simple and small this is a useful application. Tracks my network usage and gives me an idea of my internet connection speeds. The download and upload speed details are my favourite giving me the correct amount of data being transmitted and received by my system. Very active development ensures that its always ahead and updated. With additional utilities like ping, traceroute and URL grabber this should be a one stop place for monitoring your network connection. Highly configurable and simple navigation options make it one of the 'simple' best applications I have come across. Checkout FreeMeter screenshot
