Easy to use and free tool to plot functions and surfaces in 3D of type f(x,y).

How to use it:
- simply type the equation of your function in the provided field, click on OK, and a 3D graph of the function will be generated
- you can then rotate, translate and zoom into your 3D graph to inspect it
- in the settings tab, you can specify the axis size to generate the graph within your required interval

By upgrading to the full app version you also get:
- the app without adds
- export to OBJ - simply click on the export button and your graph will be exported to OBJ format that can be later viewed in most 3D modeling software
