Lies Nearly all the stuff it says you can do in the description are actually only available on the paid version. Useless and misleading.

Extremely limited No Y. On the Acer Tablet can not access the left key area in function area. Makes this limited graph useless

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