A lightweight macOS menu bar app that displays multiple clocks for different time zones side by side.
- Live clocks in the menu bar — all your configured timezones shown next to each other, updated every second
- Quick add / remove — click the menu bar icon to open the popover, then hit
+to add a timezone or×to remove one - Per-clock formatting — 12/24-hour, show seconds, show date, show/hide the label prefix
- Reorder clocks — drag rows in Preferences (
⌘,) to change the display order - Persistent — all settings saved in UserDefaults and restored on next launch
- No Dock icon — lives entirely in the menu bar
