I've been using MathPad to do curve fitting, including the sigmoid curve. 
I don't have it automatically tuning the parameters yet, though, which is
probably what you want (I've just been adjusting them manually, since I
only needed to do a few).

But MathPad's a great app to have around anyway.  Very handy.  If you can't
find anything better, let me know and I'll send you the MathPad document
I've been using.

Good luck,
