A new free app on the App Store, by the name of “HiddenApps,” lets you hide stock iOS apps and disable iAds entirely without the need for a jailbreak.
While we don’t know how the app slipped through Apple’s otherwise stringent app review process, we’re pretty sure it’ll get pulled very soon, which is why you should download the app right away from this iTunes link.
9to5Mac describes how the app manages to skirt iOS restrictions and hide inbuilt apps:
Most of these tricks are carried out in the same way: you tap a button and HiddenApps attempts to install a different app over-the-air. That installation intentionally fails, and you delete the failed installation from your home screen. Deleting this app magically triggers the intended change.
HiddenApps also lets you open apps that are hidden by default from the user like Field Test, iOS Diagnostics and iAdOptOut.
As expected, the app has been removed from the App Store.
