The official description reads, "HiddenApps is a simple and easy app that shows you tips and tricks about your iDevice." However, in actuality the app lets you: Hide apps, Disable all iAds, and launch iOS Diagnostics, iAdOptOut, and Field Test. Unfortunately, you will need to rehide apps after a reboot but that isn't too difficult.
It's highly likely that Apple will remove this app. We'd suggest downloading it now if you haven't already.
You can download HiddenApps from the App Store for free.
