CatsEyeClock

In ancient Japan, a unique method known as 'CatsEyeClock' was used by ninjas. This method involved observing the dilation of a cat's pupils to tell time, as the size of the pupils changes significantly with the surrounding light. Under bright sunlight, the pupils constrict, whereas they expand in dark conditions.

This app offers two styles: the traditional ninja style used historically, and a modern style. The ninja style from the Edo period unconditionally linked the time with the size of the cat’s pupils, while the 'light quantity style' modernly links it to the amount of light.

Today, while you can easily check the time with watches and smartphones, using this app allows you to approximate the time the moment your cat looks at you. Enjoy the time woven by your cat's eyes with this app.
