I want to built an App that helps people to figure out their App usages and perhaps reduce spending time on Apps they don't want to, in order to do that, I need to track it, so I give the user notifications if it crosses a certain value etc.
Is that possible somehow on IOS? If so, how? I've heard Facebook does something to figure out what apps do users do have. I promise I'm using it for a better reason than facebook(perhaps, to kill it).
