Hi Honey is a mobile-first wellness companion designed for people living with Sjögren’s syndrome, a chronic autoimmune condition affecting millions globally. The app helps users log meals, track symptoms, understand AI-generated health patterns, and share meaningful insights with their care team — all through a calm, supportive, non-clinical experience.

I designed the core product experience and visual foundation, focusing on simplicity for brain-fog days, emotional warmth, and scalable design systems for rapid iteration.

People living with Sjögren’s often experience:

Brain fog and fatigue

Difficulty tracking symptoms consistently

Frustration with cold, clinical health apps

Data overload without clear, actionable insights

Most existing tools feel like medical dashboards — complex, sterile, and mentally taxing.

The challenge: How might we design a health app that feels like a supportive friend, not a hospital interface, while still delivering powerful AI-driven insights?

Minimal cognitive load: simple enough for the foggiest days

Warm, human tone: “Hi Honey,” not “Patient ID #123”

Forgiving interactions: low pressure, easy recovery

Clear insight delivery: patterns explained, not just shown

Scalable system: able to expand to 60–80 screens efficiently

Established brand visual language and tone

Designed hero screens and core flows

Built a scalable component system for engineering handoff

Designed AI insight “Trigger Cards” with explainability

Created localization-ready layouts (EN / zh-CN)

I treated Hi Honey as a daily emotional companion, not a utility.

Soft neutrals and warm pastels to reduce visual stress

Large touch targets and generous spacing

Card-based layouts to chunk information

Clear hierarchy with minimal text

Gentle iconography and friendly micro-moments

Every decision asked one question:

The attached screen shows the Dashboard, the heart of the app.

Quick actions for meal logging, symptom check-ins, and sleep

AI Trigger Cards that surface patterns like food reactions or sleep correlations

Confidence indicators to explain AI certainty

Clear “why” explanations to build trust in insights

Instead of overwhelming users with charts, insights are delivered as short, human-readable stories.

Meal logging (photo + voice-first capture)

Symptom check-ins (tap & slide interactions)

Sleep hygiene tracking

AI pattern recognition & insight cards

Daily plan & adherence tracking

Care-team sharing & export-ready views

Onboarding and empty states designed for reassurance

To support fast product growth, I created:

A color system optimized for accessibility and calm

Typography scale with clear hierarchy

Reusable components (cards, badges, inputs, buttons)

iOS-aligned interaction patterns for React Native

Localization-ready spacing and layout rules

This foundation enables rapid generation of 60–80 screens without visual drift.

A warm, non-clinical health app experience

Clear AI insights users can understand and trust

A scalable design system ready for engineering handoff

A product that reduces friction for people managing chronic illness

Designing Hi Honey reinforced the importance of empathy over complexity. In health products, clarity is care, and good design can genuinely improve daily life.
