I'm looking for an app that can tell me how much time I spend on each installed iPhone app. This would be useful for identifying apps I really should delete, and also "lite" apps I really should purchase.
I know such programs existed for Palm devices. They simply looked at the clock whenever the device was turned on & off and whenever a program switch occurred (because the OS provided easy hooks for this), then just calculated running times from these timestamps.
PS: I realize that such an app must by nature be in Cydia, because non-jailbroken devices don't reveal such useful information. --> This fact can't be a reason to close this question!
