For a limited time, the iOS utility app, Data Usage, is temporarily free. This app “…monitors cellular (3G/4G/LTE/Edge/GPRS) and Wi-Fi data usage real time from your device.” And allows the user to “set data quota and billing cycle information and let Data Usage worry about making sure you don’t pay for overages again.”
App runs in background periodically, shows used, remaining or predicted % as application badge and sends you alert when you exceed specified usage level.
With this most precise tool, you are always in control of data plan limit and save hundreds or thousands on data overages by investing just $1!

★ “Data Usage is great for those who run the risk of exceeding their limit. If you fall into that category, Apple’s Settings application no longer makes the cut. That makes it a great buy!” – 148Apps.com
