We recently added the ability to search for Apps. App search works a lot like Domain search but there was one important difference: it was not possible to export Apps.
Based on your feedback, we've added export to the Apps page. Simply click on the export button in the top right corner of the page to export Apps. After a few seconds, you'll receive a CSV file containing all the Apps that match your current search. If you want to export all Apps, simply clear your search filters before you export.
