Mobile users can create a personalized schedule with the "My Schedule" feature. When downloading a Yapp on their mobile device, each schedule item will have the ability to add that item to "My Schedule." Users can see their schedule by tapping on the My Schedule icon on the top right of any schedule or multi-track schedule page.
