iPhone Clock app's alarm scroll wheel stops dead at 4:39
A quirk in Apple's Clock app has resurfaced online: rapidly scrolling the hour and minute wheels when setting an alarm hits a hard stop at 4:39 (16:39 in 24-hour format), rather than scrolling infinitely. The behavior doesn't restrict users from actually setting an alarm for any time; it only affects how far the scroll wheel spins before snapping to an end.
GoKawiil's interpretation of the reporting above, not reported fact.
Apple has not explained the cause, and online theories point to an interface component called Tableview possibly limiting the number of scrollable rows rather than any deliberate design choice. The quirk illustrates how even a nearly two-decade-old, heavily used default app can contain unexplained interface behaviors that most users never notice because they don't scroll fast enough to find them.
- Fast-scrolling the alarm time wheel in iPhone's Clock app stops at 4:39 (16:39 in 24-hour format).
- The glitch doesn't limit which alarm times users can actually set.
- Apple hasn't commented, and online theories blame a UI component called Tableview rather than confirming any official reason.
