|
[2012-08-19] A Google User: 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: Works great for free!!! If you need more out of it, then dont be stupid and buy it. I mean the going rate for a real one is $150. ITS FREE!!!!!!!! DUH |

|
[2012-02-11] A Google User: Developer, can you do a 3D version with X Y and Z axis? |
|
[2012-01-17] A Google User: Helpful Does what it says. Its suits my needs at the time (last year in high school). |

|
[2011-05-12] A Google User: Very limited utility Could find no way to scale axes independently. Not very useful if you can't do that. Cannot use physical keyboard to enter functions. No pinch and zoom at all. |
