Wondering when to schedule an international meeting? Or whether it’ll be day or night when you land? World Clock takes the guesswork out of “What time is it?”, “Can I contact them now?”, and “When should we meet?” Built for cross-border business, international trade, remote work, global teams, students and families abroad, business travelers, and anyone adjusting to a new time zone. WORLD CLOCK: SEE THE BEST TIMES TO CONNECT Add the cities you care about to see their current local times and contact windows at a glance. Daylight saving time and time differences are calculated automatically. Work hours are clearly displayed, and cities can be reordered with a simple drag. WORK HOURS & REMINDERS: NEVER MISS THE BEST TIME TO CONNECT Set custom work hours for each city (9:00–18:00 by default) and quickly see when everyone is available. Availability, work hours, and reminders can all be set in 30-minute increments, while meeting recommendations are shown at 30-minute intervals. Add reminders for specific contact windows, get an automatic notification when the time arrives, and choose a reminder sound—so you never miss the best time to reach out. TIME ZONE CONVERTER: PLAN FLIGHTS AND ITINERARIES Convert dates and times between any cities. Add multiple destination cities, view results across day boundaries, and share them with one tap. Great for flights, meetings, business trips, overseas calls, and jet lag planning. MEETING PLANNER: FIND A TIME THAT WORKS FOR EVERYONE Choose the participating cities, meeting duration, and date. The app automatically recommends the best meeting slots within everyone’s work hours, prioritizing times when schedules overlap. Non-working and Do Not Disturb statuses are clearly displayed so you can make a quick decision. Share the recommended schedule as a calendar (.ics) file or a schedule image. Meeting recommendations are shown at 30-minute intervals. WIDGETS: SEE THE TIME WITHOUT OPENING THE APP Put your favorite world clocks on the Home Screen or Lock Screen and check the time in multiple cities without opening the app. With Pro, customize widget themes and styles to match your Home Screen. OFFLINE & PRIVACY Core features work offline, so you can check times and convert time zones even in Airplane Mode. No account is required, and the app does not track your activity or use third-party advertising or analytics SDKs. Cities and reminders are stored locally on your device; your personal data is never collected or uploaded. Import or export your city list to move it easily to a new device.
