Features

Everyone's day, lined up on one screen.

Most world clocks tell you what time it is. Hourlap tells you whether it’s a good time, for everyone you work with, love or travel to.

A day bar for every place.

Every place on your Board gets a bar showing its day: working, free, weekend or asleep. Drag sideways and every clock moves together, so you can see what 3 PM tomorrow means for everyone at once.

People, not just cities.

Give a place a nickname, like Priya in London or Mom in Sydney, and its own working hours, sleeping hours and workweek. Your own Current Location row follows your iPhone’s time zone as you travel.

Find a time that works for everyone.

Hourlap ranks the next week’s meeting times by what they ask of people: after hours a little, weekends more, waking someone up most.

Clock changes, before they bite.

Hourlap warns you ahead of time, with optional reminders, and says exactly how the gaps on your Board will change.

Widgets that keep time.

Home Screen, Lock Screen and StandBy widgets update every minute. Small, medium and Lock Screen widgets are free.

Newer rules than your iPhone.

When a place changes its clocks for good, iOS can take months to catch up. Hourlap bundles the newest official time-zone rules and uses them only until your iPhone has them.

Make it yours.

Pick your own colors and icons for the day bars, or start from the colorblind-safe and monochrome sets. Patterns can stand in for color.

Try it

Drag to any time. Every clock follows.

This is a live Board for right now, worked out in your browser. Drag across the bars to try another time, and look for the column where everyone’s green.

  1. Drag sideways

    Every clock moves together, so you see that time for everyone at once.

  2. Read the colors

    Green is working, blue is free, orange is the weekend and purple is asleep.

  3. Add your city

    Type a city below the Board to add it, with 9-to-5 working hours.

  • Working
  • Free
  • Weekend
  • Asleep

Clock changes

The week the gap changes, you'll know.

Europe and North America don’t change their clocks on the same day, and the southern hemisphere goes the other way. For a week or two, twice a year, the gap you’re used to is wrong. Hourlap tells you ahead of time.

  • Reminders, if you want them.

    A notification three days before, sent by your iPhone, not a server.

  • Gaps, not just dates.

    “Priya in London will be 5h ahead of Chicago (not 6h) until Nov 1.”

  • Up-to-date rules.

    Places that change their clocks for good show the right time even before iOS catches up.

  • Chicago
  • Priya · London
  • Mia · Sydney
  • Ken · Tokyo

Questions

Straight answers, including the ones that start with “not yet”.

How is it different from Apple’s World Clock?

The Clock app shows the time in each city. Hourlap also knows everyone’s working and sleeping hours, so it shows who’s free now or at any time you drag to. It finds the best meeting time too, and warns you before clocks change.

What do I need to run it?

An iPhone with iOS 26 or later, or an iPad with iPadOS 26 or later.

Is it really free?

Yes. The free version has up to five places, Best time, clock-change alerts, and the small, medium and Lock Screen widgets, with no ads and no time limit. Hourlap Pro is a one-time purchase that adds unlimited places, more Boards and the large and extra-large widgets.

Does Hourlap collect my data?

No. There’s no account, no ads and no analytics in the app. Your Boards are stored on your devices. The app goes online only when you choose “Search Apple Maps” while adding a place, and when you buy or restore Pro through the App Store. The privacy policy has the details.

How does it know when clocks change?

From the official IANA time-zone rules, the same ones your iPhone uses. When a place changes its rules and iOS hasn’t caught up yet, Hourlap uses the newer rules it carries until your iPhone has them.

Does it work offline?

Yes. About 70,000 places are built in, and every time is worked out on your device. You only need a connection to search Apple Maps for very small places.

Is there an Apple Watch or Mac version?

Not yet. Hourlap starts on iPhone and iPad. Other devices will come only when they work as well.

I bought Pro. How do I get it on a new device?

Sign in with the same Apple Account, open Settings in Hourlap and tap Restore Purchase. Family members in your Family Sharing group get Pro too.
