Handy Carb Jetting Calculator

I have a friend who designed and is marketing this little Jetting calculator program for iPods etc. I don't know how it works and cannot try it since I don't have the proper gadget thingy to put it on. The main question I have is how it could possibly know the scale used to determine the volume difference between one jet and the next size jet of the same manufacturer. At least he doesn't seem to be overcharging for it! Maybe someone can check it out and let me know how it works.

Interesting, but alas cell phones don't work too many places here so gadget less too.

And I would like to continue using my brains instead of needing batteries and a phone every time I have to blow my nose...

Someday all it will take to win any contest or be a super hero will be the ability to walk and talk without one of those idiotic devices.
