Works as advertised – Data Usage Review

I have used the app to keep track of my data usage for years now and it's just gotten more accurate in newer versions. It's still occasionally off from what the phone company says, but it thankfully overestimates. I would recommend turning on the badge to show percent used. And keep in mind to launch the app every now and then so the badge is up to date.
