Health Hub

A personal fitness command center with AI-powered insights

Problem

Most fitness apps are either too simple or overwhelming. I wanted a single place to track macros, weight trends, and workouts — with an AI that actually understands my patterns and can have a real conversation about my health.

What I Built

Health Hub is a progressive web app that combines macro tracking, weight logging, and workout sessions into one dashboard. I integrated the USDA food database for accurate nutrition data and built an AI fitness advisor using Claude that can answer questions about my progress, suggest meals based on my remaining macros, and generate weekly insights from actual trends — not generic advice.

The app is installable on mobile as a PWA, supports dark mode, and uses Recharts to visualize 90-day weight trends and macro breakdowns.
