To make the list more complete, one might add :
grafunc (under education) and my own TouchPlot. (see also this thread)
In fact, there is another one that looks promising, although it is typically not what I, for my part, would use on a regular basis on an iPhone or iPod touch, because of the absence of a physical keyboard, and which is called Tion (under productivity I think)
I haven't bought it, so I can't tell how good or bad it is... but you could have a look at it.
