Not Doing the one thing it should do right – Data Usage Review

This app should be able to keep track of my data usage accurately, and warn me at predetermined times if I'm approaching my quota. For the second month in a row, AT&T is telling me I've gone over my limit, and this app is reporting that I've only used 50%. Seemingly, there is no way to contact the developer. Even the link to the developer website is broken. Considering misspellings in the app, poor performance, and inability to contact devs, this app deserves 1 star.
