You can access Canvas from a browser on your Android/iOS device including tablets. However, mobile browsers are not supported, and many features may not work as expected, therefore it is better access it from a desktop or download the free mobile application from the Google Play/Apple Store
Canvas Student is the mobile app for Canvas that is available to download for free for Windows, Android and iOS. The Canvas app allows you to view courses, calendars and notifications. You can also submit some assignments and take quizzes via this app.
To access your CIT modules on the Canvas app:
Search for Cork Institute of Technology (it should show in the list when you type "Cork").
Select Cork Institute of Technology and log in with your CIT Single Sign On (your CIT student ID and password).
