MUJI CAL

This is probably the only reason why I would ever want to get an iPhone...

(I'm a very proud Android user!... and let's not get into a geek-war here.)

The MUJI Calendar for iPhone.

MUJI's a Japanese living concept store that focuses on simplicity in both design and usage. Their stores are all over Japan, almost in every town, well-stocked with practically everything: furniture, clothes and shoes, to pasta and sauces!

One of the few design languages that I personally like very much, largely because of their gracious use of simple yet very contrasting typography.

Here is a Youtube Video of the application demo:

MUJI Calendar is available for both iPhone & iPad.
I wish for an Android version! :)
