One world. Onetime.

Finally, a world clock that integrates all time zones into one easy-to-read dial. We are all living and working globally more and more, so we needed a way to simply see the time in cities around the world at a glance.

That’s how Onetime was born.

Built on the metaphor of the earth’s rotation, Onetime displays all the cities that matter to you as they move through the day and night in a natural, clockwise direction referencing the international date line.

Whether you are scheduling an international call or checking to see what time it is back home, Onetime is the clock for you. No more mistakes adding and subtracting hours, no more confusing GMT numbers, no more remembering daylight savings calendars.

Onetime takes care of it all, automatically.

And with Timetravel™, you can fly through time so that you quickly find the right moment to schedule that important teleconference with your international colleagues or catch your loved ones before their bedtimes. The „Share“ feature lets you choose a date with TimeTravel and send an invite via message or email. Give up your wall of newsroom clocks and switch to Onetime today.

Onetime. By FLUID.


Onetime was created by the award-winning design firm FLUID.
With our locations in Munich and Silicon Valley and our international client base, the FLUID team is a heavy Onetime user, too.

Timetravel bug when some cities entered

Love this app. But the Timetravel feature stops working when certain cities are input.

Beautiful and it works so well

This app is simple, and yet so incredibly useful. It does what it says on the tin, and does it with great style. The interface is simple, but very pretty, and has some nice touches, like the way the day/night boundary jiggles when you pass through it.

I am surprised this is free. You can’t go wrong with this app if you need to keep track of times in more than one time zone.

Best time zone app

This is by far the best, most intuitive and beautiful time zone app out there.

I’ve been using it for years, but unfortunately it stopped working properly about a year ago.

I switched to a similar, yet inferior app a while ago. But today I decided to check onetime— one more time to see if it’s fixed.

Fortunately it IS fixed and working as well as before.

Don’t let the bad ratings and reviews scare you away from trying it.

The bug that causes the negative reviews is fixed now and the app is incredible!
