Experience the iPhone Alarm Picker: It Feels Magical Until You Discover It Stops at 4:39

When activating the alarm on your iPhone, you encounter what appears to be a traditional spinning wheel displaying hours and minutes. By swiping up or down, it seems as if you’re engaging with an infinite circular dial. However, this is a clever trick—it’s not truly a wheel, nor does it operate endlessly; instead, it’s a meticulously crafted, extensive yet finite list of time options.

Understanding the Illusion: How Apple Transforms a Simple List into a Wheel

To explore this further, open the Clock app and head over to the Alarm section. If you scroll quickly through the hour and minute selections, you will quickly find that there is an endpoint. Observations from users on X have shown that the scrolling functionality restricts you from going beyond specific times, such as 4:39 or 16:39 in 24-hour mode. This limitation serves as a clear indication that your interaction involves not a seamless wheel but rather a cleverly camouflaged list.

For those who may not be aware, the time picker employs a lengthy series of time values that repeat standard increments, creating the illusion of infinite scrolling. In reality, this system is constrained. Interestingly, some users on Reddit have turned this realization into a playful challenge: one commented, “I got 6.4 seconds before I hit the end, ” while another confirmed, “It stops at 16:39 for me too.” I can attest to this phenomenon—it operates exactly as described.

This design choice reflects a classic user experience (UX) technique, where a prolonged list, combined with strategic framing, simulates a wheel-like feature without necessitating a complex circular interface. Despite its inherent limits, the illusion appears smooth and user-friendly. The next time you set your alarm, consider swiping a bit further to uncover the trick, which may alter your perception of this feature.

In the coming months, Apple is expected to launch iOS 26, potentially integrating a true infinite scroll wheel into the system. Additionally, the company will unveil the iPhone 17 during the ‘Awe Dropping’ event scheduled for September 9. At this event, new Apple Watch models and AirPods Pro 3 will be showcased as well.
