SUG Arnsberg, developed by Stadt Arnsberg, is a free iPhone application designed for the St.-Ursula-Gymnasiums Arnsberg-Neheim. This school app facilitates seamless communication among students, parents, teachers, and staff members. It offers general public information along with an internal section accessible through personal log-in credentials.

Each class benefits from a dedicated message channel for internal communications, ensuring efficient dissemination of urgent notifications via push notifications directly to smartphones. Users can easily select and download study materials, while the personal profile feature allows for individual topic subscriptions. Moreover, the app is integrated with the Stadt Arnsberg location catalog to support students in exploring internship and apprenticeship opportunities in the region.
