"What If" grades should be available on the Canvas Student iOS app. Many students ask for this feature, especially in 1:1 iPad environments. They like the convenience of the app and know that they can sign-in to a mobile browser, but "What If" grades available directly in the app would helpful as students seek to be more efficient in their workflow.
This feature is available for Android mobile users, and it would be awesome if everyone could have the tool, regardless of their platform.
