4Follower

This official 4Follower app is published by Stichting DE 4DAAGSE. This app is meant for family members, friends and colleagues of the participants of the Four Days Marches. The app provides the follower with the whereabouts of the participants being followed. This includes information about the routes, the locations of medical service areas, the toilet facilities and the water. Also, up-to-date information about the weather. A unique feature of the app is the possibility to place encouragement messages along the route for the followed participants. A participant of the Four Days Marches will decide (within the 4Walker app) whether he/she wants to be followed or not.
