Case Study
A mobile health experience designed to support pregnant women with accessible guidance, pregnancy tracking, and reliable information throughout their journey.
Challenge
Pregnancy involves many questions, emotional changes, and practical decisions. The challenge was to create a mobile experience that could organize relevant information without overwhelming users.
The product needed to feel trustworthy, simple, and supportive while helping expecting mothers access guidance at the right moment.
Solution
I designed a mobile-first experience focused on clarity, reassurance, and quick access to important pregnancy-related content.
The interface was structured around key moments of the pregnancy journey, helping users follow progress, discover relevant information, and navigate the app with less friction.
Overview
Canguru was a mobile app designed to support pregnant women during pregnancy by providing educational content, weekly tracking, community interaction, and access to reliable guidance.
The product aimed to reduce uncertainty by organizing pregnancy information in a clearer, friendlier, and more accessible way.
My role involved understanding user needs, mapping flows, creating low-fidelity prototypes, testing the experience with users, and designing a more consistent mobile interface.
Legacy screens
Before redesigning the product, I analyzed the existing app experience to understand its structure, content, and usability limitations.
The legacy screens already included important features, such as pregnancy information, questions, articles, and community interactions. However, the interface needed clearer hierarchy, better navigation, and more visual consistency.
This analysis helped define what should be preserved, improved, or reorganized in the new experience.
Research
To understand the needs of pregnant women, we looked at how they search for information, what doubts appear during pregnancy, and which moments create anxiety or uncertainty.
The research showed that users needed more than medical content. They needed a clear, friendly, and trustworthy way to follow their pregnancy week by week.
Interview insight: “I want to understand what happens each week of pregnancy, both for me and for the baby.” — Elaine
Interview insight: “I miss having a more direct way to ask questions and get reliable guidance.” — Ana
Interview insight: “People keep asking how many months pregnant I am, but everything is counted in weeks.” — Tatyane
Interview insight: “There should be a simple chart showing how weeks and months relate during pregnancy.” — Luciana
Personas and user journeys
Based on the research insights, I created personas and mapped the user journey to better understand different pregnancy contexts, emotional states, and information needs.
The personas helped avoid designing for a generic pregnant user and clarified how the product should adapt to different levels of confidence, knowledge, and emotional need.
The journey map organized the experience into five stages: knowing, starting, using, developing, and leaving.
This helped connect user expectations with concrete product decisions, from onboarding and pregnancy tracking to educational content and community support.
The journey showed that the biggest opportunities were not only in the app’s features, but in maintaining trust and engagement throughout pregnancy.
Low-fidelity prototypes
Before moving into high-fidelity screens, I explored the product experience through quick sketches, paper prototypes, user journeys, and persona boards.
This helped organize the main flows, test different interface structures, and understand how the app could present pregnancy information in a simple and accessible way.
The goal was not to define the final visual language at this stage, but to quickly materialize ideas, compare alternatives, and make better product decisions before moving into detailed UI design.
Prototype testing
I conducted usability testing sessions with users to evaluate the mobile prototype and understand how they interacted with the app.
The sessions revealed usability issues, content gaps, and moments of confusion. These insights helped refine the flow, improve the clarity of pregnancy information, and make the experience more intuitive and reassuring.
Using a dual-camera setup, one camera captured the participant’s reactions while the other recorded their navigation on the device.
This approach helped identify not only what users did, but also how they reacted emotionally to the experience.
User flow
The user flow was structured to reduce effort and make the main actions easy to reach.
The goal was to create a predictable navigation system where users could move between pregnancy tracking, educational content, questions, and community features without confusion.
Interface and design system
A lightweight design system was created to maintain consistency across the app.
Components such as cards, navigation elements, buttons, icons, and content blocks helped organize information while keeping the interface visually coherent.
The design needed to feel human and approachable without sacrificing usability or structure.
Final experience
The final experience brought together pregnancy tracking, educational content, community interaction, and quick access to doubts in a more organized and accessible mobile interface.
The app was designed to feel clear, friendly, and supportive, helping users follow their pregnancy journey with less uncertainty and more confidence.
To demonstrate the interaction flow, I also created a video walkthrough showing how the main features work together in the final experience.
