5 AI Tools for Building Mobile Apps

An AI mobile app builder produces one of three things: a native project you own and can open in your own tooling, a hosted app that runs only inside the vendor’s platform, or a web app shipped as a PWA or inside a native wrapper.

You get asked for “a mobile app, fast,” you type a prompt, and a working preview appears on your phone. The trouble comes months later, when a developer needs to fix a bug and finds nothing to clone.

This guide compares Dactyl, Rork, FlutterFlow, Thunkable and Bubble on the same points for each: what the tool outputs, whether you can export it and on which plan, which platforms it targets, whether it can produce a store build, and roughly what it costs.

What Are the Three Output Types of an AI Mobile App Builder?

An AI mobile app builder’s output type decides what you own. An owned project (React Native/Expo, Flutter or SwiftUI source) keeps working after you cancel the subscription. A hosted app only lives inside the vendor’s platform, even if it can export a compiled binary. A web wrapper or PWA is a website packaged to look like an app.

Glide (PWAs only, with no app store publishing) and Base44 (which reaches the stores by wrapping its web app in a native shell) come up often in these comparisons, but neither is really a native mobile builder.

Five AI Mobile App Builders Compared

1. Dactyl

Dactyl generates SwiftUI and says it can take you from the browser to the App Store without a Mac. Dactyl’s homepage lays out the whole flow in the browser: you describe the app, see it built in a live preview, install it on an iPhone, iPad or Android phone, and publish through TestFlight and the App Store, with no Mac or Xcode needed.

• Export: Dactyl says you own the Swift it writes, and you can download it as an Xcode project whenever you like. Opening that export in Xcode is the one step that needs a Mac.
• Platforms: iPhone and iPad. Dactyl says the same Swift also compiles to a native Android app that you install by QR code, but Play Store publishing isn’t available yet.
• Store build: Yes. According to Dactyl’s pricing page, the free plan lets you install the app on your own iPhone using a free Apple ID, while TestFlight and App Store publishing start on a paid plan. Apple also charges $99 a year for the Developer account you need to publish.
• Pricing shape: There’s a free tier. Builder costs $20 a month and runs the AI on your own ChatGPT Pro subscription, which you pay OpenAI for separately. The $100-a-month Standard plan includes the AI, so you don’t need ChatGPT at all.
• Stops being useful: Dactyl is Apple-first, and it’s a young product. Its device docs list features that don’t work yet, such as WeatherKit, HealthKit and push notifications, so check them against what your app needs.

2. Rork

Rork has two paid tiers, and both write native code. According to Rork’s plan docs, Rork Pro builds iPhone apps in SwiftUI, Android apps in Kotlin with Jetpack Compose, and web apps, while Rork Max adds the rest of Apple’s devices. Rork used to build apps with React Native and Expo, but you can no longer start an Expo project in Rork. Existing Expo projects still build and publish.

• Export: Paid plans let you keep the generated code. Rork exports iPhone, Android and web apps to GitHub as normal projects: an Xcode project in SwiftUI and an Android Studio project in Kotlin. The sync runs both ways, so you can work in Cursor, VS Code or another editor and pull your changes back into Rork.
• Platforms: Pro covers iPhone, Android and web. Max adds iPad, Apple Watch and Vision Pro, plus native games and iOS widgets.
• Store build: Yes. Rork can submit to the App Store for you. For Google Play, it generates an Android App Bundle that you upload in Play Console yourself. iOS builds and cloud simulator sessions run on rented machines, so they use credits on top of the prompt that triggered them.
• Pricing shape: Pro costs $20 a month for 100 credits, and Max starts at $200 a month. For an iPhone-only SwiftUI app, that puts Rork Pro at the same starting price as Dactyl Builder, though Dactyl Builder also needs a paid ChatGPT Pro plan. You only need Max for iPad, Apple Watch, Vision Pro, games or widgets.
• Stops being useful: Every change you make by prompt costs credits, so a long run of small fixes adds up quickly.

3. FlutterFlow

FlutterFlow generates Flutter code, but you can’t take it with you on the free plan. Code download, APK download and app store deployment all start on Basic, according to FlutterFlow’s pricing page.

• Export: Basic and up. GitHub integration and the VS Code extension start on Growth.
• Platforms: Flutter’s cross-platform targets, which in practice means iOS and Android for mobile. The exported project is the same kind of Flutter app you’d write by hand.
• Store build: Yes, from Basic.
• Pricing shape: Free covers building with a two-project limit. Paid plans start at about $39 a month.
• Stops being useful: Once custom logic and state management outgrow the visual editor, you end up working in Dart anyway.

4. Thunkable

Thunkable is a hosted builder. It compiles Android and iOS builds, but it doesn’t export source code. A compiled build you can upload to a store is not the same as owning the code: without source, every future change has to be made inside the original platform.

• Export: Compiled binaries only.
• Platforms: iOS and Android.
• Store build: Yes. Publishing starts on the Builder plan, which allows one live app.
• Pricing shape: Builder costs $59 a month billed monthly, or $37 a month billed yearly. Thunkable’s pricing page has run promotional discounts, so check the price on the day you buy.
• Stops being useful: As soon as you need a developer to work on the app outside Thunkable.

5. Bubble

Bubble’s native mobile apps run on React Native, but Bubble doesn’t export application source on any plan. The native mobile editor launched as a public beta in 2025.

• Export: No source export.
• Platforms: iOS and Android. You can test on your own device with BubbleGo.
• Store build: Yes, on paid plans. Each plan includes a fixed number of mobile builds.
• Pricing shape: Combined Web + Mobile plans start at about $59 a month billed annually.
• Stops being useful: For new mobile-first products. Bubble fits best when you already have a Bubble web app and want the mobile app to share its backend.

Where Does Every AI Mobile App Builder Stop Being Useful?

All five AI mobile app builders are good at prototypes and simple apps. They struggle with real state management, offline behaviour and native modules: sync conflicts, background tasks, and SDKs the builder doesn’t wrap. At that point, only an owned project can move into a normal development workflow. After exporting, check that it runs without the vendor:

# SwiftUI export (Dactyl, Rork): run in the folder with the .xcodeproj, on a Mac with Xcode
xcodebuild -list    # shows the scheme names; use one in place of YourApp below
xcodebuild -scheme YourApp -destination 'generic/platform=iOS Simulator' build

# Kotlin export (Rork Android): needs a JDK and the Android SDK
./gradlew assembleDebug

# Flutter export (FlutterFlow)
flutter pub get
flutter run

If the project builds using only the standard Xcode, Android Studio or Flutter toolchain, you own a codebase and not just a subscription.

Which AI Mobile App Builder Fits Your Situation?

Choose an AI mobile app builder by what you need to keep, because every one of these tools can produce a demo.

• You want native iPhone and Android code to keep developing: Rork Pro on a paid plan.
• Your team writes Flutter: FlutterFlow on Basic or above.
• You need an Apple-only SwiftUI app: Dactyl Builder or Rork Pro, both $20 a month (Dactyl also needs ChatGPT Pro). Rork Max, at $200 a month, is only needed for Rork’s iPad, Apple Watch and Vision Pro support.
• You already run a Bubble web app: Bubble mobile, as long as you accept that there’s no export.
• A non-developer team needs a working app and accepts lock-in: Thunkable.
• Your “app” is really a marketing page, directory or form: build a website or PWA instead.

Conclusion

Judge an AI mobile app builder by what you can take away, not by how good the first preview looks. Before you commit, export a project on the plan you intend to buy and run it with the standard toolchain. If it doesn’t run outside the builder, you’re renting the app, not owning it.

FAQs

How much does it cost to publish an AI-built app to Google Play?

Google Play charges a one-time US$25 registration fee for a developer account, with no annual renewal. Apple's Developer Program costs $99 every year. You pay for the builder's own plan on top of either fee. Personal Google Play accounts opened after 13 November 2023 must also run a closed test with at least 12 testers for 14 continuous days before they can publish to production.

What are the limits of installing an iOS app with a free Apple ID?

A free Apple ID signs apps through a Personal Team. Apple expires those provisioning profiles 7 days after issuance, so you have to reinstall the app every week. A free account can register up to 3 devices and install up to 3 apps per device. Distributing through TestFlight or the App Store requires a paid Apple Developer Program membership.

Will Apple accept a web app wrapped as an iOS app?

Not if the app is only a website inside a native shell. App Store Review Guideline 4.2 (Minimum Functionality) requires features, content and UI that take an app beyond a repackaged website. Reviewers reject apps that only load a site in a web view. Web views are allowed, but the app needs native behaviour such as native navigation, push notifications or offline handling.

Can I run an exported React Native and Expo project in Expo Go?

Only if the project uses just the Expo SDK and JavaScript-only libraries. Expo Go ships with a fixed set of native modules, so any library with custom native code fails inside it. For those projects, make a development build, either locally with npx expo run:ios or npx expo run:android, or in the cloud with EAS Build. Expo says Expo Go is not suited to production-grade projects.
