The app is used for communication between the alumni of the Evangelistenschule Johanneum e. V. and also for communication among current students, lecturers and employees. Chat rooms make communication and exchange easier, a calendar provides an overview of important dates, and the alumni and the current house community can exchange ideas interactively. Push messages can be used to provide quick and direct information.

But interested parties and friends of the Johanneum can also easily access current and interesting information via the app.
