WorldTime
Read full descriptionHide full description
A timezone scrubber app that lets you visualise time across cities with an interactive dial. Most timezone apps use static displays or linear sliders. But time is cyclical — so WorldTime uses a dial interaction that mirrors how we actually think about time. Rotating the dial scrubs through hours, and concepts like "yesterday" and "tomorrow" become intuitive as you cross midnight.
