There are three ways to tracks your app usage in iOS 7. You can see how much storage space each app is using. You can see which apps are using location services, and which ones are using it at this very moment, possibly using your battery more than you would like. You can also see how much cellular data each app is using and deny apps access to data when you are away from a wifi connection.
