Joepie is an initiative of KSA for Sjo's, Simmers and Young Renewers. The 14-16-year-olds of KSA walk for 4 days with one big goal: the mysterious city of X. They receive relevant information via the Joep'App. Occasionally they miss a turn on their way. Then they can count on JOKO (Joepie Coordination). Joepie managers and registered management can call for help from JOKO via the Joep'App on the basis of a correct mobile phone number. In this way they are put back on the right track to continue their journey.

The Joep'App is only for Joepie responsibles and management during Joepie 30 of KSA (from 11 to 14 April 2023).
