Business Challenge

"How do you explain complex medical results to the average parent in an empathetic way?"

Tiny Health's microbiome testing platform was providing overwhelmingly complex results to parents seeking simple answers about their children's health conditions. With 72% of users coming to the platform specifically to address conditions like eczema, allergies, and digestive issues, the existing scientific-heavy interface was creating barriers instead of solutions.

How

Complete summary redesign

I conducted a comprehensive user research audit and applied a first-principles approach, developing a "3As framework" (Acknowledge, Address, Act) that restructured the entire information architecture around user concerns rather than raw data. Working as the sole designer with our 5-person dev team and input from our 35+ person company, I redesigned the core results experience and implemented it in phases over Q2 2025.

My role

Product & Design Lead

As Product & Design Lead, I served as the sole designer and collaborated with our part-time PM, project manager, and dev team of 5. I also worked cross-functionally with the research and clinical teams to create a more intuitive user experience.

Who I collaborated with

Full team collaboration

This screen is the main user experience of our product; therefore I got input from the entire team (35+) to ensure we built the correct flow.

Tiny Health feature overview

Discovery & definition

Users needed clarity on actions, not a science textbook.

How

Audit of user data & interviews

The team and I gathered feedback from our users about the existing report and its painpoints. We utilized in-app surveys, feedback received by our customer service, and user interviews.

Defining our scope & goals

Worked with founders and team leads to define the goals for this project:
- Increase user understanding of their results
- Reduce confusion and overwhelm
- Impact our user metrics to drive business outcomes

Findings

Parents needed a summary-first approach

"I want to know what's wrong and what I should do about it, but I'm lost in all these percentages and bacteria names." - Parent of 2-year-old

"I spent 30 minutes trying to find the recommendations. Why isn't this the first thing I see?" - New parent

Concerned parents represented 72% of users

These parents had specific needs:
- Find solutions to their child's existing symptoms
- Take immediate action to see health improvements
- Understand the "why" behind recommended changes


The existing product was designed for a scientific audience but needed to serve busy parents seeking clear guidance. Tiny Health user segments and needs

Painpoints

1. Information overwhelm

Parents were completely overwhelmed with the sheer amount of information presented on the first screen.

2. No clear summary / takeaway

While there was a lot of info, it was not summarized in a digestible way.

3. No conditions information

The conditions that parents had gotten the product for were not mentioned.

Audit: Before

Organized by scientific category

Upon seeing their overall score, users were funneled directly into scientific microbe categories that provided very little context.

Ideation & concepting

I set out to answer user questions with the 3A approach.

How

Lo-fi diagrams of key user questions in order

Mapped out the critical questions users ask when reviewing their results, sequencing them from "What's wrong?" to "What do I do about it?" to create a logical flow that matched parents' mental models. Tiny Health concepting diagram

First principles approach

Started from the fundamental question "What does a concerned parent actually need to know?" rather than "How do we present all our data?" to rebuild the experience from the ground up.

3As Emotional Framework

Designed with a framework to Acknowledge users' stated concerns, Address how their results connect to those concerns, and provide clear Actions they could take, moving from validation to understanding to empowerment.

Information Architecture Redesign

Restructured the architecture from science-first categories to condition-centered pathways that grouped related insights together and eliminated redundant information across multiple pages. And because engineering was already working on it, I slipped in a new grid system to standardize the desktop design. Tiny Health grid system exploration

Visual hierarchy

Before

Visual weight too similar. Unclear hierarchy. No summary.

After

Clear focus and hierarchy. Summary takes up the main area. After redesign visual hierarchy

Evaluation & testing

The release would need significant communications and product marketing.

How

Working prototypes sent to users

Figma prototypes sent to users for feedback, followed up by interview sessions.

Internal release

Released the feature first to a handful of internal beta testers to validate it and squash any remaining bugs before rolling out.

Findings

Users appreciated the new layout

The beta testers found that the new layout provided much more context and they understood their results better. It took some adjustment for users who had already seen their results to reorient around where content lived.

Practitioners' workflow would be impacted

Practitioners who view patient results needed a substantial walkthrough to avoid confusion on first open. We delayed launch by a week to prepare email comms, video walkthroughs, and in-app product marketing.

Final designs & implementation

Flow

Progressive disclosure of the right info

The final design answers each user question in order of importance. Tiny Health flow detail

How

Figma file with designs

Figma file containing all user flows, screens, edge cases, prototypes, and copy needed for implementation.

Assisting developers with implementation

I helped developers maintain implementation quality, testing every screen in sandbox before production.

Feature flags

The redesign was implemented in phases over Q1-Q2 2025, with careful attention to preserving existing functionality while improving UX. We used feature flags to test approaches and gradually roll out changes.

Highlighted features

One score to rule them all

The new Microbiome Summary Score gives users a quick answer to "Are my results good or bad?" as a grade out of 100. Tiny Health summary score feature

Expanded note

No need to navigate away from the results summary to read expert notes. This keeps users at the summary level. Tiny Health expanded note feature

New Conditions feature

Clear cards show the condition being tested and flagged metrics that are out of range. Tiny Health conditions feature

Impact

We saw an immediate change in user behavior post-launch.

Qualitative user feedback

Measures

NPS: ↑10 pp

Sentiment analysis showed dramatic improvements. Promoters rose from 2 out of 3 users to more than 3 out of 4. Low-score comments dropped sharply, and language became more outcome-focused, with increased mentions of "recommendations," "consultations," and feeling "empowered."

Engagement: ↑30%

We saw around a 30% lift in engagement across age groups. Tiny Health engagement metrics chart

Glowing feedback from users

"I find this format easier to follow, more digestible, and gives me clear answers. The previous format was more vague, more of a report that I couldn't really comprehend whereas this is digestible by a regular person in a way that makes sense. This is really great!" - Caroline, mother of baby with colic

Next: Resample rate

Over the next 6 months, we will monitor how our resample rate (users testing again with us) changes.

My learnings

This project demonstrated how thoughtful UX design can transform a complex, data-heavy product into an accessible tool that truly serves users' needs.

Takeaways

User context is everything

Understanding that 72% of users arrived with specific health concerns completely changed how information should be presented.

Less can be more

Reducing information overload increased satisfaction and engagement.

Design for the 80%

While some users wanted deep scientific detail, designing for the majority of concerned parents improved the experience for everyone.
