Drag the "Emoji Rating" or "Emoji Rating Large" to your app, depending on your needs. The large emoji rating is roughly twice as large as the standard one. Within the element inspector you can specify the style of the ratings element, set an initial rating (integer from 0-5) and specify if the rating element should be disabled (not clickable by user). You have access to the currently selected rating of the rating element by choosing the Emoji Rating's Current Rating. Furthermore, everytime the rating of a Emoji Ratings' Element is changed, the "A new rating has been entered" event is triggered. You can create a workflow when this event is triggered within your workflows.
