If you’re the type of person who installs tons of apps from the App Store and then only uses a small number of those after installing them, then you just might enjoy a newly released and free jailbreak tweak called Ash by iOS developer burrit0z.

Ash implements an intelligent app icon dimming effect to help jailbreakers keep better track of the apps they use and the apps they don’t use. Never-used app icons appear gray in color when being displayed on the Home Screen, whereas used app icons retain their original color, as depicted in the screenshot examples above.
