Whenever you initiate a screen recording on a notched iPhone, a red pill-shaped indicator appears over the Status Bar’s time display. This is useful for reminding you that your display is recording so you remember to stop it at some point, but iOS developer h4ckua11 had another idea for improving the screen recording indicator that would go on to become a new and free jailbreak tweak dubbed ScreenRecording Time.
As shown in the screenshot example above, ScreenRecording Time merely replaces the current time display in the red pill-shaped screen recording indicator with a timer denoting the length of time that the screen recording has been in effect. In other words, it reminds you of how long your screen recording is before you end it.
