Gave it a try, but it's inaccurate – Data Usage Tracker Review
I have a pay-as-you go card, so I thought it would come in real handy to measure usage. My limit is 100mb of cell data per month. I ran out yesterday and couldn't figured it out. Turns out, this app read 34mb and AT&T had it at 100mb. So this app doesn't seem to track the cell data very well. Oh well.
