In four weeks, I redesigned a nutrition care app. User interviews helped set priorities, and usability testing informed changes to the interactive prototypes.

Context

Care between appointments

Conecta brought together information for nutrition care. User interviews surfaced usability problems that guided the redesign.

Research

What needed to change first

I organized questions and hypotheses in a CSD matrix. After the interviews, I joined an ideation session to prioritize improvements by expected impact and feasibility.

Design and testing

Four weeks to shape a proposal

I created high-fidelity interactive prototypes and refined them through testing and feedback cycles. The delivery brought together redesigned workflows and decisions reviewed during the project.

Outcome

Results and impact

Interviews, prioritization, and testing helped the team adjust the proposal within a short timeframe. The project was completed in four weeks.

The proposal guides patients through their first use of the app and reorganizes how tasks are displayed. An internal measurement after launch found an average 50% increase in app usage time. This engagement made clinical follow-up easier for nutritionists, resulting in greater treatment adherence.
