The platform uses fMRI research from university partnerships to help millions of users train their emotional fitness through six neurotransmitter systems. It's been featured in a documentary series on the science of happiness and is expanding into clinical research applications.
Multi-Level Progression System
Transformed a neuroscience-grounded progression framework into an aspirational yet achievable journey spanning beginner through master levels. Designed comprehensive progression tracking across multiple emotional fitness dimensions with intuitive visual feedback, including range-based balance calculations, progressive complexity unlocking, and optional achievement badges that encourage exploration and community engagement. Balanced scientific integrity from university research partnerships with behavioral psychology to create meaningful early wins while maintaining long-term goals.
Design System Architecture
Created a lightweight, future-ready design system purpose-built for the product's evolution toward a chat-based interface. The system includes primitive and semantic color tokens, spacing and radius values, typography styles, and gradients—all with intelligent naming conventions that bridge design and development seamlessly. Uniquely architected for AI-assisted implementation, enabling token names to map directly from design variables to code without requiring handoff documentation.
App Store Screenshots
Created screenshot sets, visual messaging, and privacy screen illustrations that contributed to the app being featured as App of the Day across multiple countries, reaching millions of potential users worldwide. Developed privacy-forward visual communication that addressed user concerns while clearly articulating the platform's neuroscience-based value proposition.
Navigation & Iconography
Designed a comprehensive icon system for bottom navigation that maintains clarity across varied contexts while reinforcing emotional fitness positioning. The icons balance approachability with precision, serving both casual users building initial habits and committed practitioners pursuing mastery.
The design process involved close collaboration with neuroscience advisors to ensure all gamification and progression elements aligned with evidence-based emotional fitness principles validated through fMRI studies. I created interactive prototypes for rapid iteration, developed information architecture for AI coaching flows, and established a component library supporting both current features and ambitious future expansion—including the platform's evolution toward clinical research applications.
