[Blindmath] graphs on iOS (was: SAGE?)

Hi,
I will have to look into these apps. However, one major shortcoming of
today's notetakers is the lack of a way to hear a graph. The old BNS
could do this; give it a function, like x^2, and it would produce an
audio clip that traced the line, using beeps for the axes and pitch to
tell you if the line went up or down. Is anything like this available
on iOS? If I had a Mac and $99 per year I would write one myself, but
I am on Windows and do not have the money to spare.
