Yes you can, but function is limited compared to using the full Moodle website. The app is still under development at Moodle, so there are several functions that will not work properly. A better mobile option is to go to the full Moodle website on your phone's browser. This should work very much like using Moodle on your desktop's browser, and this is the method we recommend for smart phones.
If you want to try the Moodle Mobile app, it is available from both Apple App Store and Google Play for Android devices. Use your CampusNet ID and password, and when asked to enter the URL of your Moodle site, enter campusnet.sebts.edu/moodle . Just be aware that the screens you see may be missing some information, options or buttons.
If you need more information on using Moodle Mobile, see its online documentation.
