Amazing handycalc

I have download HandyCalc for number of days until now

This is handy Calculator really awesome after I view his website
While I post few questions to him


Tu YiMing, a civil colleague student at Shanghai University build this calculator since 14April 2008
You can do calculation of
Now - 14.April, 2008 = 
no of days after it was invented
(on the handy calc)

If you still not impressed, download and try it
It can be very complex for new user

I am still learning how to use it as a programmable calculator

But once you know there is a lot of help when press the Menu key
(There are tutorial on calc and lesson on YouTube ...)

Too bad it is not on open source
(could be he still earning a lot and do not want other to mess up with it)

Either he has ported to iphone

Anyway, it is a excellant application and hope he has time to further improve on it
