LifeOS Health is live

LifeOS is a personal health tracking app for logging weight, food, and exercise, with a dashboard that visualizes calorie intake, macros, hydration, weight trends, and an AI health coach for personalized guidance.

Unlike typical calorie trackers, it draws from a database of over 600,000 foods spanning Indian, Chinese, Nepali, and American cuisines, and includes body fat measurement alongside standard weight tracking. Built full stack with a Java Spring Boot backend and React frontend, deployed on Railway and Vercel with a custom domain, JWT authentication, and real nutrition data lookups.

Built with React, Next.js, PostgreSQL, Claude API, Vercel, REST API.
