EventFahrplan is the project behind a couple of apps for Android which you might already have used at Remote Chaos Experience (rC3), Chaos Communication Congress (3xC3), Chaos Communication Camp, DiVOC, MRMCD, FrOSCon, GPN, Datenspuren, FIfFKon, FOSDEM, FOSSGIS, FOSS4G, DebConf, LibreOffice Conference, PyConZA and other events. In this talk you will get to know both the details of the programming work as well as all the other topics which require time and engagement to run this project such as translation, design, documentation, advertisement, outreach, communication with users. Currently, the project is run by one person with occasional - but very welcome - contributions in the form of code reviews, translations, pull requests or just time to discuss ideas. There is essential no financial backing for the project - all work is done in personal spare time. A few people are giving money via GitHub Sponsors - thank you! After this talk and Q&A you will have solid understanding how you can contribute to the project, shape its future or finance its development.
