brainenginev0/OnSpaceBuilder ? reverse-engineered prompt

Build me a clean React Native app with Expo for a product called OnSpace AI, something that shows how a no code AI app builder works.

I want it to feel polished on iPhone, Android, and web, with a simple onboarding flow, a main home screen, and a few example screens that make the app feel real, like creating an AI app from a prompt, viewing templates, and checking progress. Use the libraries already in the project where they make sense, and wire up any Supabase based data flow if needed. Keep the design modern and friendly, with smooth loading states, icons, and a little motion if it fits.

Please make it runnable end to end, with sensible placeholder content if anything is missing, and organize the code cleanly so it’s easy to extend later. If you need current docs for Expo or Supabase, look them up online.
