It should be available in following days in the iOs app Store too (please, note that it may take up to a week).
Main new features and improvements:
- Glossary - users can browse glossary entries (requires Moodle 2.6 onwards with the Moodle Mobile additional features pluginn installed).
- Course and activity links can be followed using the app. For example, a link to a glossary entry will open in the app, or a link to a different course will show that course in the app. This allows any activity to be displayed.
- Downloaded files now keep their original name so they can be easily found by other apps (such as the PDF browser).
- Each page of the app now has a unique CSS class name. This means that specific pages may be styled by remote themes.
