**Stop doing time-zone math in your head.**
Whenmo makes scheduling across time zones effortless. Add a clock for each person's city, then drag any one of them — every other clock moves in sync. Find the time that works for everyone, then send it to their calendars.
**One gesture, every clock moves**
Grab any city's time and roll it up or down. All the other cities follow instantly, so "I can do 10am New York — what's that for everyone?" takes one swipe.
**See who's reachable at a glance**
Cities that are asleep quietly recede; cities in working hours glow. No squinting at AM/PM.
**The overlap, revealed**
Switch to the Timeline and the green "Timeline in Sync" band shows — instantly — the hours everyone is within working hours. Whenmo even names the best window for you and jumps you there with one tap.
**Turn a time into a meeting**
Found the slot? Pick a date, set a duration, and add it straight to your calendar — or share a standards-compliant invite (.ics) or a Google Calendar link. Times are sent as a fixed moment, so everyone's calendar shows it correctly in their own zone.
**Built right**
• Every distinct time zone on Earth, searchable by city or country
• Daylight-saving handled automatically, everywhere
• Cards or Timeline — your choice
• Set your home city, working hours, and 12/24-hour clock
**Private by design**
No account. No sign-up. No tracking. Whenmo collects nothing and works entirely on your device — the only time anything leaves is when *you* choose to share an invite or open Google Calendar.
Whether you're wrangling a five-country standup or just planning a call with a friend abroad, Whenmo finds the time.
