This study examines the use of an Online Application Generator (OAG) for low code mobile app design and development, focusing on transforming crisis management guidance from PDF format to a published platform-independent mobile app. We compare the level of difficulty experienced by a citizen developer and a full-stack developer, considering ease of development, customization, security, and architecture. Despite OAGs’ effectiveness in managing vulnerabilities, they pose risks such as undisclosed tracking and compliance with privacy laws. The approach was found feasible for citizen developers in terms of rapid mobile app development although we observed limitations in localization and in preserving privacy.
