Those of you using iOS 7 probably know by now that swiping down on an app's preview screen in the multitasking menu does absolutely nothing. Swiping up force closes the app, but down is useless—unless you're jailbroken.
The tweak I'm going to show you today utilizes the currently non-existent swipe-down function in the app switcher to monitor app usage stats. First, make sure you jailbreak your iPhone, then download and install SlideforUsage from Cydia. The only option for this tweak is to change the font color of the usage information, located in your stock Settings application.
