This clock App is meant for all those users who like to get the time in unusual or challenging ways. This App can display the time in many different ways, like for example as decimal time (which was introduced in the French Revolution), as hexedecimal time (the idea goes back to the 19th century), as "Swatch Internet time" and many others. The most challenging clocks are the trigonometry clock and the PT clock, which requires some mathematical or chemical knowledge to interpret the time correctly. This clock is for "Geeks" ;-) The App shows the time in big letters which are easy to read even from the distance. So you can use an (old) iOS device put it on a shelf so it just shows the time. Feel free to make suggestions for other "geeky" clocks I can add in the future...
