Copy Arc?

Build me a Health & Fitness web app like Arc.

Arc does: ARC is a premium circadian rhythm and sleep optimization app live on the iOS App Store. It helps users discover their chronotype (Lion, Bear, Wolf, Dolphin) and align their daily focus and caffeine in It reportedly makes about $65/mo, so the core idea clearly has demand — I want a lean version I can run and charge for.

Start from the open-source project Snouzy/workout-cool (https://github.com/Snouzy/workout-cool) — reuse what fits, strip its branding, and build the specifics below on top of it.

Requirements:
- Onboarding capturing goal (lose / maintain / gain), body stats, and daily targets.
- Daily logging: food (searchable food database or manual macros), workouts, weight, water.
- Dashboard: calories in vs out, macro rings, streaks, and a weekly trend chart.
- AI: describe a meal in plain English → estimate calories & macros; generate a weekly meal or workout plan.
- Reminders, history view, mobile-first responsive UI.

Also:
- Clean, modern, responsive UI with a thoughtful landing page.
- Email/password auth and a simple paid tier (Stripe test mode) so it's ready to charge.
- A README covering setup, environment variables, and how to deploy.

Ship a working MVP I can run locally first, then help me deploy it.
