joshhedstrom/healthTracker ? reverse-engineered prompt

Build me a simple health tracking web app where people can create an account, log in, and keep track of their fitness and nutrition progress in one place.

I want users to be able to record things like their weight, water intake, nutrition goals, and workout activities, then view their progress over time in a clean dashboard with charts. It should feel easy to use and be built as a full stack app with a React front end, a Node and Express server, and MongoDB for storing user data. Please include sign up and login with password security, and make the interface look polished and friendly.

Make it work locally with clear setup steps, and if you need to check anything current online while building it, go ahead and look it up. The main goal is a practical personal health tracker that is straightforward, responsive, and ready to use.
