Health Harmony: AI-Enabled Personal Health Management Platform

Founder-Led Passion Project

KinKeeper is a consumer health application designed to help individuals and families manage medical records, notes, and care coordination across multiple providers. As Product Manager, I led user research, roadmap development, and feature launches that improved onboarding clarity and expanded the platform’s core medical record capabilities. The initiative focused on simplifying the user experience while strengthening the product’s ability to centralize health information.

Business Context

Health Harmony began as a founder-led passion project inspired by my own experience navigating the healthcare system while managing chronic medical conditions within my household.

​

Like many patients managing complex care, I found myself tracking symptoms, medications, appointments, and provider information across multiple disconnected systems—including hospital portals, personal notes, calendars, and medical devices.

​

This fragmentation made it difficult to identify health trends, share critical information with caregivers, and advocate effectively during medical appointments.

​

Recognizing that many patients face the same challenge, I began exploring how a patient-centered digital platform could consolidate health information and empower individuals to better manage their care.

​

The result was Health Harmony, a mobile-first platform designed to unify personal health data, support chronic condition management, and enable more informed patient-provider conversations.

​

Why This Mattered:

  • Chronic illness management requires tracking information across multiple disconnected systems.

  • Patients often struggle to communicate trends and symptoms effectively during short doctor visits.

  • Caregivers frequently need access to critical health information during emergencies.

  • No single consumer product effectively consolidates qualitative health data (symptoms, notes) with quantitative health metrics (blood pressure, glucose, etc.).

 

What Triggered the Initiative:

  • My personal experience navigating the healthcare system while managing chronic health conditions

  • The need to track symptoms, medications, appointments, and provider notes across multiple platforms

  • The lack of a single patient-controlled platform that consolidates health information and daily health data

  • Conversations with other patients and caregivers who expressed similar frustrations in managing fragmented health information

 

These insights revealed an opportunity to build a consumer-focused health management platform designed around the patient experience rather than healthcare provider systems.

Founder Insight

Health Harmony was inspired by firsthand experience navigating the complexity of chronic illness management. While managing my own healthcare and supporting family members with complex medical needs, I realized how fragmented patient information is across healthcare systems.

​

This experience highlighted a clear opportunity: patients need a tool designed for them to manage their health information and daily care.

​

That insight became the foundation for Health Harmony.

Problem Statement

Patients with chronic illnesses lack a single, unified system to manage health data, daily symptoms, medications, and care teams across multiple providers and healthcare systems.

​

As a result:

  • Health information is fragmented across many platforms

  • Patients struggle to track patterns and trends in symptoms

  • Caregivers lack clear visibility during emergencies

  • Valuable patient-generated health data is rarely captured in a structured way

 

This leads to poor patient visibility into their own health and reduced ability to advocate for themselves during medical appointments.

Product Strategy

The strategy focused on building a patient-controlled health timeline that combines multiple categories of health data:

​

  1. Unified Health Record

    • Personal health profile

    • medical history

    • care team information

  2. Daily Health Tracking

    • symptom logging

    • medication adherence

    • daily health metrics

  3. Care Coordination

    • provider directory

    • appointment management

    • shared information with trusted individuals

  4. Future AI-Driven Insights

    • trend detection

    • symptom analysis

    • medication guidance

    • health coaching via an AI assistant

 

The MVP prioritized patient-controlled data entry and daily engagement loops before expanding into third-party integrations and AI analytics.

Product Vision

If patients could track daily health data, medications, and symptoms in a single platform, they would be more empowered. Health Harmony aims to become a centralized platform where individuals can track symptoms, organize medical records, and generate insights that support more informed conversations with healthcare providers.

My Role:

Founder, Product Manager, & Prototype Developer

​

Scope of ownership:

  • Product vision and strategy

  • User research and persona development

  • PRD development

  • Product roadmap definition

  • Feature prioritization

  • UX design direction

  • Prototype development

  • Initial technical experimentation

 

Decision authority:

Full product ownership across:

  • product strategy

  • feature roadmap

  • architecture direction

  • MVP scope

​

Team size:

  • Solo founder

  • Supported by external development partners during early planning

​

Cross-functional partners:

  • Healthcare professionals (informal consultation)

  • Patients managing chronic conditions

  • Early prototype testers

​Key Actions I Led:

  • Conducted user research with individuals managing chronic conditions and caregivers

  • Defined the product vision, personas, and feature roadmap

  • Designed the core data architecture for patient health tracking

  • Built a detailed Product Requirements Document (PRD) outlining features, workflows, and release criteria

  • Created early UX concepts and workflow diagrams for the mobile application

  • Defined success metrics across engagement, retention, and product loops

  • Built the first functional prototype independently using Replit to validate product concepts and workflows

  • Designed the MVP to support testing with 10+ individuals managing chronic care conditions

 
Product Strategy Decisions:

Tradeoffs Made:

Prioritized manual health tracking over integrations

  • Integration with healthcare portals and wearables adds complexity

  • MVP focused on validating user engagement with daily health tracking

 

Mobile-first experience

  • Chronic illness management often happens in real-time

  • Mobile access enables daily tracking and quick data entry

 

Simple onboarding vs comprehensive health history

  • Initial setup designed to be quick and iterative

  • Users can gradually build their health profile over time

 

What I Said No To:

  • Billing and insurance integrations

  • Mental health–specific treatment features

  • Pediatric or non-adult patient use cases

  • Full caregiver platform in the MVP

  • Complex AI features before validating data collection

 

These were intentionally deferred to later phases to maintain MVP focus and reduce development complexity.

 

How I Prioritized:

Features were prioritized using three criteria:

  1. User value for chronic illness management

  2. Daily engagement potential

  3. Technical feasibility for MVP

 

Initial MVP features included:

  • Personal Health Profile

  • Care Team Management

  • Medication Tracking

  • Appointment Management

  • Daily Symptom Check-Ins

  • Health Record Timeline

 

These features formed the core daily engagement loop needed to validate product value.

​

Senior-Level Signals:

This project demonstrates:

  • Identified a product opportunity through firsthand experience with healthcare system fragmentation

  • Founder-level product thinking

  • Experience designing healthcare products in regulated environments

  • Ability to translate personal insight into scalable product strategy

  • End-to-end product ownership (vision → PRD → prototype)

  • Technical curiosity through building a working prototype using Replit

  • Strong focus on behavioral engagement loops and data architecture

 
What I’d Do Differently:

If restarting the project today, I would:

  1. Conduct deeper, structured user interviews earlier in the process

  2. Prototype faster using low-code tools before writing a full PRD

  3. Validate daily engagement loops sooner with real users

  4. Explore strategic partnerships with healthcare organizations earlier

  5. Define the AI roadmap after collecting sufficient patient data
