From YUDU Media:
The YUDU Proofing App allows you to view and test your interactive digital editions on an iPad or iPhone before publishing to your own branded app. Once you have completed enhancing your pages with video, slideshows, links or dynamic layers you can set the edition to Proofing in order for it to appear in the Proofing App, which you can access with the same log in details as YUDU Pro.When you have checked over your edition, to ensure that pages are accurate and correct, you will need to tap the tick icon on the edition toolbar to mark it as Proofed, and either go back to YUDU Pro to make additional changes or request that the edition be published live.If you have any questions about the app or your edition please email email@example.com
