Hour Atlas: World Clock

Your places. Their time. One glance.

A focused world clock for seeing local time, daylight, and working-hour overlap across the places and people that matter to you.

What it does

See your world at a glance

Save the cities that matter and see their local time, date, daylight, and offset from you in one clear list.

Compare the same moment

Move time forward or backward and every place updates together, so planning across time zones stays concrete.

Find a good time to connect

The aligned grid highlights local working hours and finds the next shared window across your saved places.

Understand the daylight

See sunrise, sunset, day length, UTC offset, and upcoming daylight-saving changes for each place.

Keep it on your Home Screen

World Clocks and Time Grid widgets make your saved places visible without opening the app.

Ready from the first tap

Start with New York, London, and Tokyo as examples, or build your own atlas from the bundled city catalog.

The same moment, made visible

Hour Atlas is for the people who regularly translate “my afternoon” into somebody else’s morning. Save the places that matter, choose a moment, and every local time updates together.

The separate time grid aligns each city by hour, highlights 09:00–17:00 locally, and finds the next shared working-hour window without mental arithmetic.

More than a row of clocks

Each place includes sunrise, sunset, day length, UTC offset, and the next daylight-saving transition. Rename a city for the person, office, or team it represents, then share a proposed time with every local equivalent included.

Native, local, and free to use

Hour Atlas is built for iPhone and iPad with native controls, Home Screen widgets, and no account. City search and solar calculations work offline, while saved places remain on your device and are shared only with the widgets you add.
