GlobalSync World Clock widget showing San Francisco, New York, London and Tokyo with live skies and call status

Everything a remote team checks, in one glance.

Made for people whose teammates, clients and family are spread across time zones.

A live sky for every city

Each clock shows its city's real sky right now: dawn, daylight, golden hour or a starry night. Thirteen cities have hand-drawn landmarks, from the Golden Gate to the Charminar.

Know when to call

Every city carries a plain status: Good time to call, Starts in 40m, After hours, Asleep or Weekend. Weekends follow each country's working week.

Preview any time

Drag the timeline to see all four clocks at a future time, then copy the times as a ready-to-paste list for your invite. It returns to live time after 90 seconds.

Four clocks, 160+ cities

Search by city, country or airport code, plus every official time zone. Star your home city, reorder by dragging, and add a teammate's name to any clock.

Stays out of your way

Grab it anywhere and put it anywhere. It snaps to screen edges, remembers its spot across monitors, and hides or reappears with Ctrl+Alt+Shift+W (⌘⌥⇧W on Mac).

Tiny, private, offline

A 1.6 MB download that uses your system's own browser engine. No account, no tracking, and nothing leaves your computer. It works with no internet connection.

Questions

Is the GlobalSync World Clock free?

Yes. The widget is free to download and use, with no account, trial or ads.

Does the widget collect any data?

No. Your cities and settings are stored only on your computer. The widget sends no analytics and makes no network requests. The only exception is opening globalsync-ai.com when you click its link.

Why does Windows or macOS show a warning the first time?

The app is new and not yet code-signed, so Windows SmartScreen may say "Windows protected your PC". Choose More info, then Run anyway. On a Mac, right-click the app, choose Open, then Open again. You only need to do this once.

How many clocks can I show?

Up to four at a time. To swap one, hover over a clock, press ×, then add another. Removing a clock can be undone.

Does it handle daylight saving time?

Yes. Times come from the official IANA time zone database built into your operating system, so daylight saving changes and half-hour offsets such as India (UTC+5:30) are always correct.

How do I move or hide it?

Drag any part of the widget except the buttons and the timeline. Press Ctrl+Alt+Shift+W (⌘⌥⇧W on Mac), or use the tray or menu-bar icon, to hide it or bring it back.

How do I uninstall it?

Windows: Settings → Apps → Installed apps → GlobalSync World Clock → Uninstall. Mac: quit it from the menu-bar icon and drag the app from Applications to the Trash.
