Quick answer
Offline world clock with a home-screen widget and time-zone converter.
Zham is a clean, fast world clock — see the time across the world, on your home screen, with a built-in time-zone converter.
Features:
* World clock — track the current time in as many cities as you like, with live seconds and country flags. * Easy to manage — search 600+ time zones to add a city, swipe to delete, drag to reorder. * Time converter — scrub a time and date to see the matching moment everywhere at once; pick any city as the reference and spot day rollovers at a glance (+1d / -1d). * Make it yours — Light / Dark / System theme and any accent color, via a colour wheel. * Home-screen widget — resizable, scrollable, matches your theme, and self-updates every minute. * Flexible format — 12-hour / 24-hour presets, or your own custom pattern.
Zham runs entirely offline: no accounts, no network access, no tracking. Your cities and settings never leave your device.
