Lies Nearly all the stuff it says you can do in the description are actually only available on the paid version. Useless and misleading.
[2012-07-04] A Google User:
Extremely limited No Y. On the Acer Tablet can not access the left key area in function area. Makes this limited graph useless
[2012-05-17] A Google User:
Serious problem Doesn't display parts of functions where slope is near vertical.
[2012-04-18] A Google User:

Should Mention DEMO Very limited. Can only graph a function & look at it, options for trace, roots, table of values, etc. are disabled.

Developer, can you do a 3D version with X Y and Z axis?
