About ZoneSync

ZoneSync is a world clock for people who work across time zones. It shows standard 12-hour and 24-hour time together for each city you save, so you never mentally convert between formats.

How to use

  • Search cities.

    Find any city or region. Partial names work too.

  • Tap to add.

    Build your list. Already-saved zones are marked.

  • See both formats.

    12-hour and 24-hour update every second, side by side.

  • Reorder anytime.

    Move your most important zones to the top with the arrow controls.

Data and privacy

Your saved zones stay on this device. No accounts, no cloud sync, no tracking.
