Yes, the Canvas iOS application does work with Savvas Realize content. When a teacher or student opens an LTI content link in the iOS application, Canvas will open the Safari browser to allow the LTI flow to work.
The Schoology apps for iPad and iPhone use a limited "preview" window that prevents certain content from opening correctly.
Due to this limitation:
Students and teachers cannot launch Savvas Realize.
Students cannot open content that requires a new window, like the full Realize Reader eText.
Teachers cannot add Savvas content to courses using the app.
Recommendation:
To avoid these issues, please use a web browser (like Safari or Chrome) on your iPad or iPhone to access Schoology instead of the mobile app.
How You Can Help:
Schoology prioritizes fixes based on user feedback. Please submit a support ticket to them explaining how this limitation impacts you and your students.
