DataMan Next

DataMan Next offers a widget for iOS users' Notification Center, and it forecasts whether they'll be staying inside their data limits for the month. If you're into simple design, this might be the one for you. It's $1.99 and available for iOS. There's also a DataMan Pro version for $5.99.
