Scheduling across timezones
is broken. We fixed it.

Drag a slider to find a time that works for everyone — then copy it straight into Slack.

Find the best meeting time

Stop guessing. See the overlap.

Every world clock app shows you what time it is somewhere. Fuseau shows you when everyone is actually available — as a visual timeline, not a list of numbers you have to cross-reference yourself.

Common questions

How do I find the best meeting time across multiple timezones?
Open the "Find overlap" tab in Fuseau. It shows a 24-hour timeline for each city and highlights the window where everyone's working hours line up. Tap "Copy suggestion" to get a ready-to-paste message.
Is Fuseau a free world clock app for Mac?
Yes — Fuseau is free for up to 2 cities. When you first open the Overlap Finder, you get a 7-day free trial of all Pro features. After that, Fuseau Pro is $2.99 one-time and unlocks unlimited cities, the overlap finder, and menu bar customization.
Does Fuseau live in the Mac menu bar?
Yes. Fuseau runs entirely from the menu bar — no Dock icon, no separate window to manage. Click the menu bar to open the clock panel.
What macOS version does Fuseau require?
Fuseau requires macOS 14 Sonoma or later.
How is Fuseau different from other world clock apps?
Most world clock apps only show you what time it is now. Fuseau lets you drag a slider to any time and instantly see what that means for everyone else — and it works both ways. Pick any city as the anchor, not just your local time.
