We create apps that inspire. Like Khronos…

Inspired by the medieval astronomical clocks, and the ancient Antikythera mechanism, Khronos is a multicultural timepiece for the modern age, for iPhone or iPad.

Showing dates in the Buddhist, Chinese, Coptic, Hebrew, Indian, Islamic, Japanese & Persian calendars as well as the Gregorian, and tracking the position of the sun, moon and major planets round the sky at your current time and location, Khronos V illustrates the changing relationship between our earthly calendars and the heavenly cycles on which they are based.

Packed with information, it shows dates of equinoxes and solstices in any of the calendar systems, length of day, phase of the moon and more, all in an attractive graphical presentation.
