Tapping the XTRA button will bring up the Extras panel where you can choose several extra features of Viewfinder, among them is Modules, the module store.

You can access other edition's features and camera/lens data by purchasing a Pro Pack or Cine Pack module. Purchasing the Pro Pack will unlock all the features of Viewfinder Pro, as well as purchasing the Cine Pack will unlock the Cine features and camera data. To check the different editions' camera and back list, see the Pro edition camera list and the Cine edition camera list pages.

If you restore or reinstall your device, or just want to have a newly purchased module available on all other iOS devices you use, tap the Restore Previous Purchases button. The module store will check what modules belong to your Apple ID and activate them.
