Mobile phones have been established as devices for the interaction with objects from the everyday world, such as posters, advertisements or points of interest. However, the usage of physical mobile applications is often still restricted by fixed content and behavior, whose authoring usually requires a considerable coding effort. This paper presents an approach to an authoring tool that separates the creative process of authoring content and behavior for mobile applications from its technical deployment. The tool supports non-technical users in the creation of content and behavior for the mobile guiding application MOPS that associates its content with points of interest in the real world through Physical Mobile Interaction.
