Your world,
at a glance.
A world clock for people who live across time zones. Watch a living 3D globe track day and night, find the perfect moment to connect, and never do time-zone math again.
Features
Quietly useful, every hour.
Interactive 3D globe
Watch the day/night terminator move across the Earth in real time, with every city you track pinned right on the globe.
Golden Hour meeting finder
The Timeline view automatically highlights the best overlapping hours across every city you track.
Add any city in seconds
Search by name, with smart aliasing so obscure but relevant zones surface too — searching “Alaska” surfaces Adak.
100% private, by design
No account, no analytics, no network calls, no location access. Meridiem just reads your iPhone's time zone, and everything stays on your device.
A look inside
Designed for twilight.
Privacy
Nothing leaves your phone.
Meridiem has no backend and makes no network requests. The only thing it stores is the list of cities you choose to track, saved locally on your device.
