Design and implementation of a mobile application for organizing financial commitments between friends

This Master's thesis concerns itself with the proposal and implementation of a mobile application for the Android operating system, developed in the Kotlin language. The application helps users resolve financial obligations between friends. This work will acquaint the reader with the process of proposal and implementation of the Android application. The initial part is an introduction of applications which concern themselves with a similar theme, and these are subsequently compared and rated based on specified criteria. Based on the results of this analysis, a requirement for the proposed application is created. Prior to the proposal, the selected technologies are introduced based on these requirements. After the selection of technologies, the reader is familiarised with the proposal of the application and the description of the individual parts of the proposal. The description of the implementation follows, and interesting or problematic parts of the proposal are discussed. Subsequently, user testing is described, after which the reader is introduced to the process of application deployment onto the Google Play store. The final chapter describes the avenues for further development, which are derived, among other things, from the feedback received during user testing. The key results, along with the application itself and the associated source code, are the findings described in the thesis, which can facilitate the process of proposal and implementation of the readers own mobile application for the Android platform in the Kotlin programming language.
