Even though our smartphones are getting more efficient with each and every new release, we, as users, still have to some thinking for ourselves. But even though it’s largely down to us to keep tabs on things like battery and data use, there are still plenty of apps out there that can help, and one of the better ones for iOS has just gone FREE for a limited time. DataMan is not only incredibly accurate and thorough, but offers a very palatable user interface that remains in-keeping with the overall aesthetic of iOS 7. Once installed, it not only lets you keep track of how much data you’re using, but can also forecast, based upon your activity, how much you will use in the future.

It usually costs $1.99, but is free of charge until April 4th. Grab it via the link below to save yourself at least two bucks, and if you regularly face overage charges, a whole lot more! Enjoy!
