THE TOOLS

The Debido app was born out of an observation: the gap between the desire to save water and the lack of real-time data. Using a comprehensive UX approach, I designed a mobile interface that transforms raw data into a fun and engaging experience. The goal is to raise user awareness and bring about lasting change in consumption habits through gameplay and accurate tracking by water point.

The main challenge was to structure a user experience that could be adapted to a variety of profiles. I had to prioritize key features and create complex usage scenarios to transform an administrative task (tracking bills) into a smooth daily interaction. The challenge was to design a gamification system powerful enough to maintain long-term engagement while ensuring optimal usability, tested through successive iterations.
