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.
