Worth the Money

This is a simple but useful app that does exactly what it says. It has two small problems. The RESET button will zero out your usage even if you hit Cancel and it only works in portrait mode if you hold the iPad right side up. (I often use my iPad plugged in with the power cord & home button at the top). Aside from that it is very handy and absolutely essential when connected over cellular.
