Hidden Limit in iPhone Alarm Design Revealed by Users
Imagine you're setting your alarm on your iPhone.
You spin the wheel to pick the time, and it seems like it goes on forever, right?
Well, it doesn't!
There's a secret stopping point.
If you keep spinning the wheel for a long time, the numbers stop at 4:39 AM/PM (or 16:39 if you use the 24-hour clock).
Apple made it this way to keep things simple.
The wheel looks like it spins forever, but it has a hidden limit.
This way, the time picker works without having to create an endless scrolling option.
