chetan3854/cal-ai-clone — reverse-engineered prompt

Build me a polished mobile first clone of the Cal AI app, the kind of experience that feels great on a phone and walks people through a clean onboarding flow before they start using it.

I want it to look modern and smooth, with the same general vibe as the original product and the community Figma, including simple welcome screens, questions about the user, and a clear path into the main app. After onboarding, add the core calorie tracking experience in a simple way, ideally with an AI powered food analysis flow if the key is available, but make sure the app still feels complete even if the AI part is unavailable. Use sensible fallback states, loading states, and helpful empty screens.

Please make it feel production ready, responsive, and easy to run locally. Keep the UI consistent and clean, and make sure the demo works well in mobile view since that seems to be the main use case. If you need details, look up the current product and docs online.
