Find more about Time Tracker

CircleTime comes with all the standard features like syncing with iCloud and other accounts. Viewing, editing and adding new events. Setting alarms. Time tracking. Showing birthdays and Facebook events. Displaying day length. These are the everyday things that most calendar apps can do. CircleTime goes far beyond that. It is an extremely advanced calendar which was waiting for centuries for the modern technology of touch screens. Only this technology has enabled us to take time presentation to a whole new level. We are very proud of CircleTime. It allows us to perceive time from an entirely new perspective.

So what does CircleTime have that other calendars do not?

A round, spinning calendar

It's the first calendar which allows traversing through time by spinning it forward or backward. Circle is a natural shape as it is presenting cycles in the nature, and it opens the calendar to a completely new dimension.

Circular time presentation

CircleTime is a round calendar which displays time like a clock does, on a daily, monthly and annual basis. This is a unique way to visually present the time position for the current day.

Time difference between arbitrary dates

It is exactly the circular shape of the calendar which enables us to present and perceive certain interesting and useful information, something no calendar could do before. For example, the visual and numerical display of time difference between arbitrary dates.

A unique clock view with events

CircleTime displays events in two distinct ways. Listed on the scrollable table view and as coloured arcs on the clock or 'day' view. Especially amazing is the combined presentation of this list and clock view on the iPad. Switching between days is simplified with finger swipes in the appropriate direction.

Video presentation

"You have noticed that everything an Indian does is in a circle, and that is because the Power of the World always works in circles, and everything tries to be round.

In the old days all our power came to us from the sacred hoop of the nation and so long as the hoop was unbroken the people flourished. The flowering tree was the living center of the hoop, and the circle of the four quarters nourished it. The east gave peace and light, the south gave warmth, the west gave rain and the north with its cold and mighty wind gave strength and endurance. This knowledge came to us from the outer world with our religion.

Everything the power of the world does is done in a circle. The sky is round and I have heard that the earth is round like a ball and so are all the stars. The wind, in its greatest power, whirls. Birds make their nests in circles, for theirs is the same religion as ours. The sun comes forth and goes down again in a circle. The moon does the same and both are round. Even the seasons form a great circle in their changing and always come back again to where they were.

The life of a man is a circle from childhood to childhood, and so it is in everything where power moves. Our teepees were round like the nests of birds, and these were always set in a circle, the nation's hoop, a nest of many nests, where the Great Spirit meant for us to hatch our children."
