66% of the parents said they would use MediNest frequently, because paper files and WhatsApp aren’t proper healthcare.
In this eight-week UX design project, I worked independently as the lead UX researcher and product designer. During the discovery and ideation phases, I conducted user research, surveys, and usability testing to identify families’ pain points in managing children’s medical documents.
Challenge: To design a simple, intuitive mobile app that allows users to store, search, and share their child’s medical records — while receiving timely appointment reminders — all from a single, easy-to-use platform.
Solution: MediNest is a mobile application that enables parents to securely store, organize, and access their children’s health records in one place. It simplifies appointment tracking and provides an easy way to share records with schools, doctors, and caregivers — giving families peace of mind and control over their child’s healthcare journey.
Research
Recognizing the complexity of the prompt, i broke it down into manageable subproblems and defined clear research goals to address each one.
Research goals
Research Methodology
I conducted user research with a remote survey. The survey helped highlight real concerns and gave direction for the next steps. Even though the sample was small, it provided early signals about what mattered to parents.
User Research Survey
The survey questioned users about challenges they face in maintaining health records, How do you keep track of child's upcoming health visits, and How do you typically retrieve and print your child’s health records when requested by schools or camps?

Insights: I found out that participants were still using traditional methods of healthcare record management and appointment tracking.
Key Findings and User Pain Points
After Creating Empathy Maps from all the responses, i analysed them and deduced the following User pain points.
User Personas
Based on the user pain points, I created two provisional personas to capture and communicate user insights throughout the design process.
Ideation
The Ideation stage focused on generating a wide range of ideas. I employed popular methods such as Crazy 8 sketches for each problem statement and 'How Might We' questions to explore and develop diverse initial concepts.
Final Decision Rationale
The final decision was made based on a structured evaluation of three critical criteria:
User Pain Points: Focused on solving the key challenges identified through research.
​
Usability: Designed to be intuitive and easy to navigate for a seamless experience.
​
Accessibility: Ensured inclusivity by accommodating diverse abilities and meeting accessibility standards.
​
By prioritizing these criteria, the design delivers a user-centered, functional, and inclusive solution.
User Flows and Site Map
To communicate the concept and information architecture, I developed the site map, user flows, and defined the overall product framework.

Storyboarding
To ground the concept in real-life scenarios, I created quick storyboards illustrating how parents interact with their child’s health records. These sketches helped me visualize frustrations (too many records, scattered data) and imagine how the app could simplify their experience.
​
By mapping everyday moments, I identified the core opportunity: give parents a single, easy way to create, manage, and access health records—reducing stress and saving time.

Lo-Fi Sketches
I explored multiple design options for each screen, consistently aligning them with the target audience, company mission, and objectives to effectively showcase customer success stories.

Prototype
Lo-Fi Prototype
I created a low-fidelity prototype from the user flow diagram and wireframes to quickly validate the core functionality and interaction patterns.
This allowed me to gather early feedback, identify usability gaps, and make iterative improvements before moving forward.
By doing so, I ensured the design was both accessible and intuitive for end-users before developing the final high-fidelity version.

Usability Study
After creating the low-fidelity prototype, I conducted a usability study to evaluate how users interacted with the design. The goal was to identify usability issues early, gather feedback on navigation and clarity, and uncover opportunities for improvement before moving to high-fidelity mockups.

Usability Study: Findings
The findings from the usability study highlighted areas where my lo-fi prototype fell short, allowing me to frame these as design challenges for improvement.

Hi-Fi Prototype
Based on the usability study insights, I refined the design by repositioning the CTA for better consistency, enhancing the visual hierarchy to guide user focus, and simplifying labels for clearer communication.
These refinements not only addressed user pain points but also improved overall usability and flow.
I then translated these improvements into detailed mockups, which formed the foundation of the final high-fidelity prototype.

​
Accessibility: The color palette was chosen to meet WCAG AAA contrast standards, ensuring clear readability across devices and for parents in low-light conditions.

Validation
To confirm MediNest’s effectiveness, I ran a System Usability Study (SUS) where parents rated their experience across key aspects of the app. The results strongly validated the design:
2 out of 3 parents strongly agreed they would use MediNest frequently — clear adoption potential.
83.4% of parents said they wouldn’t need any technical support — proving accessibility and ease of use.
83.3% felt confident managing health records independently.
99% agreed the main user flow was clear and easy to follow.
All participants successfully completed core tasks like record creation and appointment tracking.
Next Steps: To strengthen validation, I would expand testing with a larger, more diverse group of parents, refine onboarding for faster adoption, and introduce automated vaccination reminders to support long-term engagement.
