Vienna Late-Night Helper is a web application designed to help people find essential services during late-night hours in Vienna.
The goal was to improve convenience and accessibility by using open data.
Erasmus students reported that they didn’t expect early closing grocery stores or pharmacies.
E.g. Viennas pharmacies operate on a rotating duty calendar with 24 distinct groups and these duty groups change daily at 08:00 AM sharp to ensure 24/7 coverage. Regulations like that are not obvious especially if you are an Erasmus student.

This project has been realized by the students Jihye Seo, Hyungjun Kwon and Battogtokh Temuulen in June 2026 as part of the course Data Ethics and Open Data at the UAS Technikum Wien as part of the StudyATHome hub. This course is also part of the project IoCEST – Internationalisation of the Curricula in Engineering, Environmental, Smart Cities and Sport Technologies which has been funded by the City of Vienna.
