Gamification techniques can be applied to smart city apps to increase citizen engagement. The document analyzes NotiCity, a smart city app developed by KES that allows citizens to report issues in their cities. NotiCity was updated to include gamification elements like points, levels, leaderboards to motivate reporting. The server and client sides were modified, and the UI was restyled to be more immersive. Studies show gamification will be increasingly used in innovation and citizen engagement projects in the future.
