If you work with people in other countries, or have family and friends abroad, you keep doing the “what time is it there?” math. World Timeboard does away with it. Add your cities and their current times sit side by side on one screen; slide one control to see a meeting time in everyone's local time.
From checking what time it is to finding a meeting slot that works for everyone.
Every city's current time on one screen, each with a 24-cell bar coloring work hours, early morning, evening, and late night.
Pick a date, move the slider, and see every city's local time and suitability instantly — work hours, weekends, and holidays included.
Scans 48 slots a day to recommend the best time for everyone. Tap a column in the city × 24-hour overlap heatmap to jump there.
Take any time in any city and convert it to every other city.
A world map with a live day/night line and city pins — see at a glance where it's day and where it's night.
Alarms that ring by the other city's local time, and keep up when daylight saving changes.
Every time calculation uses only the device clock and the OS's IANA time zone data.
No server communication, no login, no account — it works the same on a plane. Your city list and
settings are stored only on the device and never sent anywhere.
Viewing times, adding and removing cities, and the meeting slider have nothing to do with ads.
Rewarded ads unlock only extras (24-hour banner removal, extra city and group slots, additional
best-time and calendar uses, clock skins, watermark removal, full time zone search, holiday data),
and those still unlock when no ad is available or you're offline.
Holiday data is offline reference data — please check official calendars for actual schedules.
Add your cities, see every time side by side — and plan meetings with one slider.
