In your schedule or multi-track schedule pages, you can turn on session feedback via the page settings popover for the page, which is accessible by clicking the gear icon on the selected page in the left hand side of the Editor interface.

When turned on, users will be able to rate and provide feedback on a session via their mobile devices. After changing this setting, you will need to publish your app for your users to see the feedback module on mobile.

 You will be able to see your results via the analytics page for your app.
