The city is the hand. London at 4 o'clock means it's 4 PM there. Tokyo at 10 means 10 AM. City names replace clock hands on a single dial. They move in real time, just like hands would. White center = daytime. Dark outer ring = nighttime. One glance tells you the time in every city and who's awake right now. No lists. No math. No switching between clocks. Pick up to 8 cities. That's it. Built for remote teams, frequent travelers, and anyone tired of googling "what time is it in Dubai." Apple Watch, iPhone, iPad, Mac. No account. Works offline.

Verdict
The clearest difference is ads: worldclock.today at none against ASG Clock's shown. ASG Clock's advantage is update cadence (daily vs every 2 months) and iOS requirement (14.0 vs 16.0). On price, in-app purchases and device support there is nothing between them.
