Lumi Ring is a smart wearable and AI-powered companion app that helps users decode emotional patterns and build healthier habits. By translating physiological data into personalized insights, it supports emotional resilience and daily wellbeing.
As the founding product designer, I created the end-to-end experience—from defining the product’s visual identity to designing a conversational, adaptive interface. I also developed Lumi, the empathetic AI twin character, which serves as a guide for turning raw bio-data into relatable, actionable feedback.
