Kort helps to improve OpenStreetMap-data. Missions to be solved are shown on a map. As soon as three players have solved the same mission with identical answers, its solution is then updated in OpenStreetMap.
Kort uses Gamification to motivate users to play with the app. By solving missions, points (so called Koins) can be earned. The goal is to progressively rise in rank. Additionally, the player is awarded medals for his efforts.
