Overview
Parameter is a patient-facing genetic health app designed to reduce health data fragmentation. By centralizing daily health metrics, wearable signals, and medical reports into a single experience, Parameter helps people understand how their data connects over time and what it means for their health.
Design Challenge
How might we design a trusted experience that turns fragmented health data into clear, actionable guidance?
Problem Space
Health data is everywhere, but rarely feels clear
What's happening today
People have more access to their health data than ever, from wearables, labs, and provider portals. But that data lives across disconnected platforms, often filled with medical jargon and numbers without context. Patients are left to connect the dots themselves, turning scattered information into decisions without clear guidance.
1.0 Patients juggle disconnected sources across labs, wearables, and provider portals.
Solution
One place to understand your health
Our goal
Parameter brings together fragmented health data into one unified view. Powered by an AI-native experience, it turns complex health information into clear, contextual guidance tailored to each user, with a modular dashboard that lets them surface what matters most.
Key Features
From raw metrics to understandable, personalized guidance
How the experience works
Parameter is designed around four connected moments: data integration, trend visualization, report interpretation, and proactive recommendations. Together these layers reduce cognitive load, improve comprehension, and help users translate information into practical next steps.
Patient Dashboard
Surfaces trends through clear, approachable visuals
Highlights changes over time and key anomalies
Helps patients quickly understand what needs attention
Data Aggregation
Brings together lab results, wearable data, and manual logs
Normalizes different formats into one timeline
Creates a stable foundation for interpretation
AI Guidance Layer
Interprets complex reports in plain language
Connects related signals across data sources
Suggests proactive next steps users can discuss with providers
Data Aggregation

Context
Health literacy and data accessibility remain major barriers to prevention.
Why this matters
Even when data is available, many patients struggle to understand what a value means, how urgent it is, and what to do next. The gap is not only access, it is interpretation. This creates an opportunity for products that communicate clearly, build trust, and guide action without overwhelming users.
User Interviews
Reactive dashboards create reactive behavior.
Research insight
Patients repeatedly described uncertainty after seeing results without explanation. They wanted context, trend direction, and confidence about what deserves attention now versus later. This insight reframed the experience from data delivery to decision support.
2.0 Research highlighted that interpretation—not collection—is the biggest patient pain point.
Competitive Research
Today’s tools are improving, but still fragmented for patients.
Competitive takeaway
Across wearables, portals, and consumer health apps, we observed strong point solutions but weak continuity. Each tool solves part of the journey, yet users still have to assemble the full story themselves. Parameter positions itself as the connective layer between these isolated moments.
Iterations
Translating complex healthcare constraints into a usable product flow
Journey Mapping
Mapped patient touchpoints across pre-visit, visit, and post-visit momentsIdentified where confusion and drop-off most often happenDefined opportunities for clearer, proactive support
Information Architecture
Structured how reports, metrics, and AI explanations relatePrioritized readability and progressive disclosureAligned navigation to real patient questions
UI Prototyping
Designed high-fidelity flows for dashboard, reports, and recommendationsTested visual hierarchy for trust and clarityRefined interactions to support confident decision-making
Reflection
Key takeaway
Designing Parameter reinforced that trust in health products comes from clarity, not just capability. The most valuable shift in this project was moving from “showing more data” to “supporting better decisions.” It also sharpened my approach to information architecture in sensitive domains where language, hierarchy, and timing directly impact confidence.
Next Steps
Paths for further development
Clinical Validation
Evaluate recommendation quality with clinicians and domain experts to improve medical reliability and safety.
Personalization Engine
Expand adaptive models that learn from user behavior, preferences, and history to make guidance more relevant over time.
Data Partnerships
Integrate directly with additional labs, providers, and wearable ecosystems to reduce manual upload friction.
Longitudinal Testing
Run longitudinal pilots to measure comprehension, confidence, and behavior change across longer care cycles.
