Overview
Making digital impact feel personal.
Trace turns abstract CO2 numbers into small, daily actions people can actually take.
The Challenge
People care but don't know where to start.
Existing apps were guilt-heavy and disconnected from daily habits. Digital emissions had to feel approachable, not accusatory.
Research
Starting with a real person.
A persona, journey map, and user stories defined the full scope before any screen was drawn.
Key Screens
14 screens, two core flows.
Onboarding guides users to a personalised footprint. The action flow surfaces one daily task and celebrates completion quietly.
Testing & Iterations
Three participants. Five findings. Nine changes.
Real usability testing surfaced specific issues. Every finding was documented and directly addressed in the next iteration.
Outcome
A full UX process, start to finish.
Research-led design from persona to tested prototype. The full UX process documented end to end.
