Gnomon: Team Time Zone Planner
See when your team overlaps
Only for Mac

Mac
Every teammate’s hours on one 24-hour timeline. Drag the playhead and read every local time at once. Working days, real sunrise. No account. No tracking.
Gnomon puts your whole team on one 24-hour timeline — who’s working, who’s asleep, and where the overlap is — so finding a meeting time stops being arithmetic.
Add teammates with the city they work from, the hours they work, and the days they work. Gnomon lays every schedule on a shared axis. Drag the playhead — the shadow — and read everyone’s local time at once. Finding the slot is the whole job; you schedule it wherever you already schedule things.
BUILT FOR REAL TEAMS
- Working days, not just hours — a Sun–Thu week in Dubai renders as exactly that
- Overnight shifts wrap the axis correctly; a 5 PM–5 AM day belongs to the day it starts
- Keep separate teams — a client, a squad, a shift — and switch the board between them
- Menu bar badge shows how many teammates are available right now
- Import or export the whole roster as CSV — eight people in one paste
- Two desktop widgets: the team board in miniature, and a column of clocks
- Current weather beside the time for your teammates and zones (Gnomon Pro)
TIME MATH YOU CAN TRUST
- DST transition days really are 23 or 25 hours here — the layout follows
- Half-hour and quarter-hour zones (GMT+5:30, GMT+5:45) print correctly, always
- Day/night glyphs come from real sunrise and sunset — NOAA solar equations, per city
- ~34,000 cities searchable offline; the zone is the truth, the city is the label
PRIVATE BY ARCHITECTURE
No account. No analytics. No server of ours. The only network requests Gnomon ever makes are reverse geocoding, when you press “Use My Location,” and — with Gnomon Pro, only if you turn on Weather — Apple Weather for whichever rows you’ve turned it on for. Nothing else leaves your Mac, and neither does your roster.
Free for up to 3 teammates, 3 watched zones and 2 teams, with the widgets and CSV import and export included. Gnomon Pro removes all three limits and adds current weather, as a one-time purchase or an annual subscription — the same full unlock either way.
Gnomon: the rod on a sundial. Not the dial, not the numbers — the part whose shadow tells you where you are in the day.
Gnomon Pro Annual renews automatically each year until cancelled; manage or cancel it in your Apple Account settings.
Gnomon Pro Forever is a single payment and yours forever.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Weather, on the rows you choose — part of Gnomon Pro.
- See the current temperature beside the time for your teammates, your watched zones, or both
- Turn it on in Settings → General, or from the Weather menu in the menu bar
- Follow your location and the footer shows the weather where you are
- Click a temperature to open Apple’s Weather app
- Readings come from Apple Weather, refresh at most once an hour per place, and follow the time of day, not the playhead
Weather is included with Gnomon Pro and off until you turn it on. Gnomon Pro is now available two ways: a one-time purchase, or an annual subscription. Nothing else changes: the timeline, the widgets and CSV import and export stay free.
