I'm in Beijing. My family is in Vancouver. I used to do the math on my fingers, or open the world clock twice. Now I turn the phone sideways onto the charging stand and both cities stand there side by side. I just look up. TWO CITIES, ONE SCREEN Two clocks, stacked or side by side, each on its own city's time. No more counting hours. FOUR LOOKS Flip, for the mechanical clack of a split-flap board. Glass, when you want it clean. City Day & Night, to see at a glance whether it's light over there. Single City, when you only care about one. WHAT'S THE WEATHER THERE Each clock carries the current conditions and temperature. Faster than asking "is it cold where you are?" IT DIMS WHEN IT GETS DARK THERE Night brightness follows the city on screen, not your phone. When it's night on their side, that half dims and the stars come out. Easy on the eyes at 3am. IT FINDS THE PLACE A built-in worldwide city database that also includes universities and high schools - search "Stanford University" and it's there. Anything missing is looked up online, and saved only if you pick it. Cities you use often float to the top. LOCK SCREEN AND HOME SCREEN WIDGETS Small, medium, large, extra large. The larger sizes show dates and weather for both cities at once. LANDSCAPE, ALWAYS ON The screen won't lock while the app is open - it's built to sit on a desk, a nightstand, a charging stand. Works in both landscape directions, so it's upright however you set it down. PRIVACY Location is optional. It's used only when you turn on GPS mode, to show the time and temperature where you are.
