Is this software sellable?

[frodo_man]

Hi all,

I just developed a piece of software and trying to sell it online these days. you can find it here: xmartcalc.com


there are obviously issues about this product, functions, user interface, website design... but the most important thing I want to know is

whether this is a good product (useful features for people )?

all advice are appreciated.

thanks.
