From the developer:
goldenRATIO is a cute little App providing an easy way to design websites, interfaces, layouts etc. according to the golden ratio - also know as the divine proportion.
This 'golden' ratio has been used by mankind for centuries. Its use may have started as early as with the Egyptians in the design of the pyramids - or at least they were the first passing on a measurable proof.
