The Status Bar is a persistent element that presents itself in the vast majority of iOS apps and user interfaces. The lone exception to this rule of thumb would of course be full-screen apps such as mobile games, video playback, and a small number of other exceptions.
Despite being hidden from the aforementioned interfaces, iPhone users can open Notification Center to view the Status Bar by swiping down from the top of the display to reveal a grabber and then tugging down on the grabber. Unfortunately, this is a multi-step process and rather cumbersome, and that’s the chief reason why a new jailbreak tweak called Grabbi by iOS developer Arielgavrielov exists.
