the-momentum/open-wearables ? reverse-engineered prompt

Build me a self hosted web app that brings wearable health data into one place with a simple API and a clean developer dashboard.

I want users to be able to connect devices like Garmin, Apple Health, Whoop, Oura, Fitbit, Strava, and similar services, then see their health data normalized in one system. The app should have a backend API, a frontend portal, login for an admin account, API key management, user management, and basic stats and data views. It should also be easy to run locally with Docker Compose, with a setup that creates an admin user on startup and lets me seed some sample users and activity data for testing.

Please make it feel like a real product, with a polished dashboard and API docs I can open in the browser. If anything is unclear, look up the current docs online and keep the implementation aligned with the project’s existing setup.
