Atlas Zones
Every city's day on one timeline, with a meeting planner for shared working hours.
Atlas Zones shows what time it is in the cities you care about, and what that time means for the people there.
Every city gets its own strip: a horizontal bar for the whole day, midnight to midnight, split into 24 marks. Night is dark, morning and evening are muted, working hours are light blue. A thin amber line shows where the city is right now, so one glance tells you who is asleep, who is at their desk and who is about to log off.
At the bottom sits one slider for all of them. Drag it up to twelve hours either way and every strip, clock and date recalculates at once, so you can see what your evening looks like in Tokyo or whether Sydney is already on tomorrow. When a city has moved to the next date, that date turns amber. One tap on now brings everything back to the real time.
Offsets are worked out properly, not guessed. Each city has a base offset from UTC, including the half-hour and quarter-hour ones such as India and Nepal, plus a summer-time rule: none, European, American or southern hemisphere. The app checks the actual date, so the numbers change on the right Sunday, and the weeks in March when Europe and the USA are out of step come out right too.
The planner is for meetings. Pick the cities, set the working hours you want to use, choose a day, and Atlas Zones marks in green the windows when everyone is at work at once, with the local time for each city underneath. If there is no shared window, it tells you so and shows the closest you can get.
The list holds up to twelve cities from a built-in set of forty. Type a few letters to find one, tap a card to move it up or down, remove it, or make it your home city, which always stays on top. Clock style, working hours, hour marks, the slider step and vibration are all in the settings.
Everything is built in and stored on the phone. No accounts, no sign-in, no network calls, no ads and nothing to buy.
