To refresh the screen in the SortScape iOS or Android app, use the "pull-to-refresh" gesture. Touch the screen, drag downward with your finger, and then release it. This will refresh the contents of the screen.

For pull to refresh to work, you have to first scroll to the top of the schedule. On iPhones this can be achieved by touching the phone's status bar at the top. Android doesn't offer a similar shortcut, so you will have to scroll up manually.
