This program was designed to work with Graphing Calculator and preview the projects. Graphing Calculator Viewer gives you access to various sample files and tutorials, lets you choose between multiple view modes, and comes with a comprehensive help guide.
Its interface is intuitive with view settings which are very simple to configure. Also, you can study the tutorials to learn how to handle the program.
The utility might prove to be of good use to students or Math professors if they wish to visualize Graphing Calculator graphs on Mac. This app displays 3D animations which can be rotated at any desired angle, allows you to change the resolution of the main window if necessary, and zoom in or out the graph.
One thing that bothers me about this program is the fact that it occasionally slows down the performance of my Mac, especially when playing the video tutorials or graph animations. Also, you can only preview the graph files, you cannot alter them by changing the equations elements.
Personally, I think it's worth installing this free app only if you don't have the Graphing Calculator program on your computer. You can use this viewer to check the projects you created in the aforementioned utility and that's it.
