Can a prompt replace Adalo?

Build a schema-driven mobile app generator using Expo (React Native), not a true drag-and-drop visual builder — that's real UI-builder engineering out of proportion for a personal tool. Define an app's data model as a JSON config: entities with typed fields (text, number, image, boolean, relation to another entity). From that config, generate standard screens: a list screen per entity with search, a detail screen showing all fields, and a create/edit form, using a fixed, configurable-but-not-arbitrary visual theme (a color and font choice, not free-form layout). Back the data with a hosted API (Node/Express with Postgres) that the Expo app talks to. Support basic auth (email/password) gating access to the app's data. Run the result as a real Expo app installable via Expo Go for testing, without requiring an Apple or Google developer account for development. Document the separate, real steps needed to actually publish to the App Store or Play Store, a paid developer account and the store review process, rather than pretending that's automated — it isn't, for anyone. Do not build a visual drag-and-drop canvas, a component marketplace, or automated store publishing — those are out of scope. Requires hosting for the backend API; an Apple or Google developer account only if you actually want to publish to app stores, which is a separate cost this build doesn't include.
