Best native app builders: four questions that settle what “native” means, and where each tool lands

1. What language is the user interface written in? Swift and SwiftUI on iOS, Kotlin and Jetpack Compose on Android, is native. JavaScript or TypeScript with React Native, or Dart with Flutter, is a cross-platform framework that renders native or near-native controls — a legitimate choice, not the same thing. HTML in a wrapper is a web app.

2. Does the app run inside a browser engine? If the vendor’s answer to “can I open the app in a browser too?” is “it is the same app”, it is a web app in a shell. Native apps do not have a web address.

3. Can I open the project in Xcode or Android Studio — and on which plan? This is the question that turns “native” from a marketing word into an asset. A Swift project that opens in Xcode is one any iOS contractor can quote on; a bundle that only builds on the vendor’s servers is not. Ask on which plan export is included; the answers vary from “any plan” to “not offered”. AI app builder code export has the plan-by-plan table.

4. What do I get for the second platform? Four possible answers: nothing (iOS only); a second project to prompt and pay for separately; one codebase in a cross-platform framework; or one project whose features are written once and rendered natively on each platform. The first column of the table is the fourth answer.

Modaal. Each feature’s logic is written once: from the Duet documentation, “Each feature’s logic — its state, the actions that change it, the effects it requests — is written once,” and “The iPhone app renders that state in SwiftUI; the Android app renders it in Jetpack Compose.” The output is an Xcode project and an Android Studio project on your disk on every plan, including Free; your own AI agent, on your own subscription, does the writing, and a plan is shown for approval before code changes. Android support is available to every Modaal account; building both platforms is a Pro feature (€9 per user per month billed annually, €15 monthly — /pricing). It needs a Mac. That is the whole tier as of September 2026: no other builder read for this page describes one project producing a SwiftUI app and a Compose app.

Rork. Native, and both platforms — as separate apps. Its documentation: “One Rork project can hold an iPhone app, an Android app, and a web app at the same time. Each app has its own code,” and “Rork writes a real Android Studio project in Kotlin.” Export: “Paid users own all generated code. Download it via GitHub!” For a product person the difference from tier 1 is the second sentence — each app has its own code, so a feature is prompted, reviewed and maintained twice.

Superapp. Apple only. Its site: “Superapp generates production-ready native Swift code from your descriptions,” with no Android mentioned anywhere on the page, and “You fully own the code and can export it anytime.” A Swift project that opens in Xcode; the Android version is a different tool.

Bitrig. Apple platforms in Swift, with “Export your code at any time” on the Free plan. Same shape as Superapp: native, one platform, project on disk.

These are not web apps and are not what question 1 calls native; they are React Native or Flutter, which the vendors describe accurately. The right comparison for them is React Native vs native.

Newly. “Built with React Native and Expo, your apps compile to real iOS and Android native code — not webviews.” Source export offered.

Vibecode. Its FAQ: “Your apps are built using React Native and Expo, which compile to native iOS and Android code.” Download gives “a complete React Native/Expo project”.

Bolt. Its Expo integration page: “Expo is a platform that lets you build mobile apps for both iPhone and Android using the same code.”

Draftbit. React Native and Expo; “Build for web, iOS & Android”; code import and export.

Adalo. Its developer documentation: “Our mobile builds use React Native.” Code export is not offered as of September 2026 — the feature request on its forum has run since 2022 without a staff answer.

Bubble. Native mobile is in “public beta”, on React Native: “Our current version of React Native will support: iOS devices running version 15.1 and later, Android devices running version 12 and later.” Export: “Bubble apps can only be run on the Bubble platform; there’s no way of exporting your application as code.”

FlutterFlow. Flutter, in Dart: “The lib/ directory contains all the Dart code that drives your Flutter app.” Code download is on paid plans.

Thunkable. Its site says “native iOS and Android”; the pages read for this page do not state the framework or whether code can be exported — ask question 3 before deciding.

Lovable, and the other browser-first tools, build web apps. Lovable’s FAQ: “Lovable does not generate React Native projects.” Their store route is a progressive web app or a Capacitor wrapper, which is a web page inside a native shell — a fine answer for some products and a different page: turn a website into an app covers the three routes and Apple’s guideline 4.2 on it.

Decide the second platform first (question 4): if Android is on the roadmap at all, a tool that gives it as a second project or not at all is a second budget line. Then decide ownership (question 3): whether the project must open in Xcode and Android Studio for a contractor to take over, and on which plan. Only then the framework (questions 1 and 2), and only if the difference between SwiftUI and React Native matters to your users — for most consumer apps it shows in how the app follows platform updates, such as the iPhone Duo changes, which arrive in Apple’s own UI parts first.

Whichever tier, the input is the same document: the one-page PRD. A builder that takes a PRD and produces a plan to approve before code is the shape product managers already work in — Modaal for product managers.
