Dabble DB allows you to share data between your Applications. To facilitate this, you tell one of your applications to re-use a category from another. (You need at least two applications to do this.)

Go to the category configuration. Categories available for sharing from other applications will be listed on the side. Click any category to add it and all of its entries to the current application.

When you add a shared category to your application, the application inherits all of the Entries that belong to that category. Any subsequent changes to the data in those entries will affect both applications. In most senses, a shared category acts exactly like a regular category. The exception to this is that if you delete a shared category from your application, it will not remove the entries since they will continue to exist in the original application.
