Using Moodle on iPhone and other mobile devices
Moodle works well using the regular browser on most mobile devices without any app.
Moodle HQ have developed a Moodle Mobile app which is available through iTunes for IOS and the Google play store for Android. This app appears to have some good features, although we have noticed some limits in functionality for UNE's customised version of Moodle.
If you do use an app, Cloud based services such as Dropbox and Google Drive may be beneficial.
