Tempus clock markTempus Get Tempus

World clock · iPhone, iPad + Apple Watch

Every time zone.
One glance.

Tempus is the world clock for people who work, travel, and stay close to the people they love — named clocks, instant conversion, and a meeting finder that actually finds the meeting.

Why Tempus

Built for people juggling time zones, not tourists checking one.

Clocks with names, not just cities

Add a clock for a city or a person — “Mum in Sydney,” “Design team, Berlin” — with a custom name, emoji, and color tag so it’s readable at a glance.

Convert instantly

Pick any time in any zone and every clock updates together. Drag the time scrubber to slide through the day and see who’s awake.

Find a meeting that actually works

Set working hours per clock and Tempus shows the overlap. Add it to your calendar in one tap or share an .ics invite.

Private by design

No account, no ads, no tracking. Your clocks live on your device and in your own private iCloud database.

See how it works

01 · Meeting Finder

Find the window that works for everyone

Select two or more clocks, set working hours for each, and Tempus highlights the overlap. Tap a slot to add it to your calendar or export it as an .ics invite.

02 · Time Converter

Drag once, see every zone move

Pick a time in any clock and every other clock updates with it. Drag the scrubber to slide through the day; day/night dots show who’s awake.

03 · City Detail

A place, not just an offset

Tap any clock for a full city view — a skyline that shifts with the time of day, sunrise and sunset, and current conditions from Apple Weather.

04 · Apple Watch

Time on your wrist

Tempus on Apple Watch shows your clocks, converts with the Digital Crown, and offers complications for your favorite cities. Clocks sync instantly between iPhone and Watch.

Home Screen widgets and iCloud keep every device in sync.

Privacy first

No accounts. No ads. No tracking.

Tempus doesn’t know who you are and doesn’t want to. Your clocks are stored on your device and, if you turn on iCloud, in your own private iCloud database — never on our servers, because we don’t have any. Weather comes from Apple Weather for the cities you add, never for your location.

Tempus 1.1 · Now on iPad

More room for every time zone.

Tempus 1.1 is a native iPad app, not a stretched-up phone screen. Your clocks sit in a sidebar and stay there while City Detail — skyline, weather, sunrise and sunset — fills the pane beside them. Time Converter and Meeting Finder open in that same detail column, so a full day of overlap finally has the width it needs. Portrait or landscape, iPad Pro or iPad mini, the split holds its shape and your selection stays put.

  • Clocks in a sidebar with City Detail open beside them — you no longer lose the list to look at one city.
  • Time Converter and Meeting Finder run in the detail column, with a full-width overlap timeline.
  • iPad toolbars in place of the floating controls, plus menu commands and keyboard shortcuts.
  • Pointer hover highlights rows and cards, and Manual sort lets you drag the sidebar into order.

Version 1.1

Also new in 1.1.

  • A searchable emoji picker

    Adding or editing a city opens a real picker instead of a text field: emoji listed with their names, suggestions that already know the city you chose, your recent picks, and a search box that also takes a pasted glyph.

  • The whole sun arc

    City Detail draws the complete sunrise-to-sunset curve — apex, sun marker and all — at every card width, instead of flattening off at the top of the card on wider screens.

  • Tel Aviv, drawn

    Bespoke skyline art for Tel Aviv — the Azrieli towers, Bauhaus blocks and the Old Jaffa clock tower — in day, golden-hour and night states, like the other curated cities.

Questions

How do I add a clock?

Tap + on the clock list, search for a city, then optionally give it a custom name, emoji and color.

How do I convert a time?

Open Convert, choose a source clock and time, or drag the scrubber. All your clocks update together.

How does the Meeting Finder work?

Pick two or more clocks, set working hours for each, and Tempus shows the windows where everyone is available. Tap a slot to add it to your calendar or share an .ics invite.

Why don't I see weather?

Weather is optional. Turn it on in Settings › Weather. It needs an internet connection and is provided by Apple Weather for the cities you added, never for your location.

My clocks are not syncing to my Apple Watch.

Make sure both devices are signed into the same iCloud account and that the watch app is installed. Opening Tempus on the iPhone triggers an immediate sync to the watch.

Can I use Tempus on iPad or Mac?

iPad, yes — version 1.1 is a native iPad app with a clock sidebar, City Detail beside it, keyboard shortcuts and pointer support. There is no separate Mac app.
