ZoneClock – Time Zone Planner

All your time zones on your Home Screen. A widget that keeps the whole day in view, plus a planner to find a time that works for everyone.

ZoneClock makes it easy to keep track of the people and places you work with across time zones.

PLAN MEETINGS ACROSS TIME ZONES Drag the slider or tap any hour to see what time it is in every city at once. Working hours are highlighted in green and night hours are dimmed, so you can spot a time that suits everyone at a glance.

NEVER MIX UP THE DAY When a city is already on tomorrow, or still on yesterday, ZoneClock shows the weekday right next to the time.

ANY CITY IN THE WORLD Pick from popular cities or search for any city or region. Half-hour and 45-minute time zones like India, Nepal and Newfoundland are shown correctly.
