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.

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.

First impressions very good


I works for a global organization. Keeping track of what time it is everywhere is really annoying. This app makes it crazy simple. Easy set up. Perfect interface. Nothing negative to say.

Nice Little App


Very unique time tracker app.

A huge plus for those who travel for a living or those going on an around the world vacation!
