Is Omnigraph available for iPads?
No, there is no version of Omnigraph available for iPad anymore. There was one called OmniSketcher, but the company didn't make it available anymore. I have checked the website and the only way to obtain the application is by contacting the developers using the data from the following page: https://www.omnigroup.com/omnigraphsketcher/
Many thanks , Alex , for taking the time to answer my question. I think I will look for another graph app even though I use Omnigraph with my class on the desktops.
