iOS apps can be refreshed simply by pulling down with your finger while the app is loaded onscreen. A small star-shaped icon will appear towards the top of the screen letting the guest know they are refreshing the app.
Note: The app must support refreshing by this method in order for this to work. Most Punchh Loyalty apps support this feature by default to refresh the guest account.
