Most "AI app builders" say they build apps. What they actually ship is HTML running in a browser tab. Real native iOS and Android code — the kind you upload to the App Store or Google Play — is a different engineering pipeline, and only a narrow slice of no-code AI app builders produce it end-to-end.

This article opens the hood. How does a plain-language prompt turn into a Kotlin + Jetpack Compose project and a Swift + SwiftUI project, each with its own architecture, design system, and build files? What's in the archive when the export button finishes? And when you compare vendors, how do you tell a tool that emits production-grade native code from one that wraps a webview and calls it "native"?

TL;DR-Key Takeaways

A full-stack native mobile app is a complete, compilable Android (Kotlin) project and a separate iOS (Swift) project — not a transpiled web page, a PWA, or a WebView shell.

Producing native code from a prompt runs a six-stage pipeline: intent parsing → screen graph → design tokens → layered…
