Will Canvas work on my mobile device?
Canvas is built on open web standards and uses minimal instances of Flash, so most features are supported on mobile devices. With the growing use of mobile devices, instructors should build their courses with best practices for mobile in mind.
You can access Canvas on your mobile device through any mobile browser. However, mobile browsers are not officially supported. We recommend using Canvas mobile applications for an improved user experience.
We are actively improving our native mobile applications to support as many Canvas features as possible. Instructure has four native mobile applications free for download on both phones and tablets. Please note that mobile applications are only supported in English at this time.
Canvas by Instructure (iOS 7.0+, Android 4.0+). This app provides access to Canvas for both instructors and students while on the go. Depending on your device, not all Canvas features may be available on the app at this time. View Canvas mobile features by version and device.
MagicMarker (iPad only, iOS 7.0+) This app is specifically designed for instructors to assist them with standards-based learning. Syncs with the Learning Mastery Gradebook.
