This thesis presents the development of an app for mobile devices intended to access the Galaxy bioinformatics service to monitor the status of running analysis jobs. The Galaxy service is widely used in bioinformatics and uses a web-interface, but the interface design did not anticipate the rapid adoption of mobile technologies, such as smartphones and tablets, and so is difficult to use on a small touchscreen device. A bioinformatics project in Galaxy can often involve several steps where each step depends on the results of previous computations. The analysis processes for such computation jobs can run for a long time, potentially days or weeks. Further progress often depends on the result, and may require new such jobs, creating a chain of analysis processes building upon previous results. The Galaxy Portal app developed in this thesis provides a way for researchers to easily monitor the status of their jobs on a mobile device as a more convenient and efficient way to track progress than returning to a computer at regular intervals. The app was developed as free and open source software using the GNU General Public License (GPL), using a cross-platform framework, with the source history, binary releases and user guide freely available on the GitHub code repository. A completed version of the app was also distributed on multiple operating system platforms, including the Android and Apple's iOS marketplace, and so is freely available to be installed on an iPhone, iPad or any Android device. The app is currently on version 1.1 with focus on monitoring running jobs, but also provides additional functionality for inspecting results and metadata. Developing a mobile app using the GPL open source license created legal challenges that were overcome by dual licensing the software and underlying framework. As part of this thesis a short paper was written and submitted to a scientific journal, and additional authors from the faculty at the university of Oslo and the Galaxy team in the US were invited to participate.
