Just set it & forget it! – DataFlow Pro - Track network data usage Review

Setup is dead simple. You only need to change it when your plan changes. There are many widgets to choose from. I use the one that shows data & wifi usage up until the limit you set. It also shows live dl/ul in progress. Thanks to this app I no longer have to go into the Settings app and wonder how much data I'm using.
