The apps' contents can be local or remote.
A remote content is a content that isn’t in the application, but hosted in a server (a URL). To see a remote content, the app connects to the server and gets the content. This is done almost instantly.
Usually, remote contents are used in those sections that, due to their nature, are going to be continuously updated.
Once this kind of content is updated, it’s automatically shown on the app, and the user doesn’t have to download and install it again.
A local content is in the application itself. When the app’s installed, all contents are uploaded.
These kind of contents can be used for sections that aren’t going to be frequently updated, such as the information about a company or its contacts.
