City guide application design examples

The design examples for a city guide application describe different scenarios for designing a first-time purchase in your application, and a restoration of content that the user has purchased earlier. A scenario for providing help to the user is also provided.

In the design scenarios for this application, the purchasable content, city guides, is not protected with built-in DRM, and it is located on a back end server. The server also stores details of users' past transactions, which enables restoring previously purchased guides to the user.
