I did some beta testing of the "Visual Dyno" software and the input and output sreens are very well done. I found it quite useful and A LOT easier to use than the math cad and excel calculators I built my self.
I have no financial interest in this, I'm posting the web page address FYI and as a favor to my friend who wrote the program.
