TimeHue is a clock that represents time as a series of hue values ranging from 0° to 360° within in the HSL color space.

To read the clock, start from the center and move outwards, just as in any classic clock: the hue of the small circle represents hours, the middle continuous hue represents minutes and the surrounding outer hue represents seconds. The segmented color wheels are merely there for reference, broken into 12 and 60 segment color segments.

The sleep (or "auto-lock") feature of your iOS device can be activated/deactivated by touching the icon in the bottom right corner. By setting this feature to "off" your device will not enter into sleep mode, allowing for a 24-hour clock display. Please note that this can result in battery loss if left for long periods without charging.
