The Single Edition model provides small to midsize design studios and freelance designers a way to deliver brochures, catalogs, portfolios, and training materials to the iPad. To create a custom app for the iPad that contains a built-in folio, either become an Adobe Creative Cloud member or pay a one-time fee. If you have a full (not individual) Creative Cloud membership, you can create an unlimited number of Single Edition iPad apps.
Single Edition apps you create work only on the iPad, not on the iPhone or Android devices. With Single Edition, your apps do not include many features such as a library, bookmarks, social sharing, and analytics that are available to Professional and Enterprise DPS subscribers.
