A complete mobile studio, powered by an AI that ships.
Other AI tools hand you a mockup. AppNative hands you a running React Native app, the source code behind it, and the tools to keep going.
An engineer that checks its own work
AppNative's agent doesn't just generate code and hope. It explores your project, makes coordinated changes across files, and validates the build after every request, retrying until it compiles.
- Uses real tools: read, write, patch, search, rename, install and more, the way a developer would.
- Bundles the app after each change and automatically fixes build errors before reporting back.
- Checks the running preview for runtime crashes, not just compile errors.
- Stop it anytime. Keep chatting to iterate on the same feature.
- Runs on fast open models with automatic failover between providers, so you're not stuck behind a rate limit.

Caught a typo in its own import and fixed it. You only saw the working result.
See it on a phone the moment it's written
Your project runs on a real Metro bundler with React Native Web, right inside the tab. Edits stream in through Fast Refresh, so the preview updates without losing your place.
- Pixel-accurate iPhone 15, Pixel 8 and iPad frames with notches, status bars and home indicators.
- Portrait and landscape, zoom from 50% to 200%, and one-click reload.
- Build errors surface right on the device with a Fix with AI button.
- Open the app in its own window for full-size testing.

2 of 4Real code you can read, edit and trust
Every project is idiomatic Expo + TypeScript, organised the way a senior developer would set it up. Jump in whenever you want. The AI picks up your edits on the next request.
- The Monaco editor that powers VS Code, with TypeScript IntelliSense and syntax highlighting.
- File tree, autosave, and instant preview refresh on every keystroke pause.
- Expo Router file-based navigation and a centralised theme: change a color once, every screen follows.
- Integrated terminal and a problems panel with parsed errors.

Make it yours without touching config files
A visual settings panel for everything that makes an app feel like a product. It writes directly to app.json and your theme, so the code and the UI never drift apart.
- App name, slug and URL scheme.
- iOS bundle identifier and Android package, generated for you from the app name.
- Primary and secondary brand colors applied across the whole app.
- A screen list showing every route, one click from its source file.
The npm ecosystem, minus the guesswork
Not every native module can run in a browser. AppNative knows which ones can, simulates the ones it can't, and makes sure your code guards the rest, so the preview keeps working and the device build does too.
- Built-in compatibility registry for popular Expo and React Native packages.
- Versions matched to your Expo SDK automatically.
- Unsafe or unsupported packages are flagged before they break your build.

- react-native-svgWorks in preview
- expo-hapticsSimulated in preview
- expo-cameraDevice only · guarded
- react-native-reanimatedWorks in preview
Versions are pinned to your Expo SDK automatically, so installs don't break the build.
Your app. Your code. No strings.
Download the entire project whenever you like, or keep it in sync with a GitHub repository. It's a standard Expo app: run it locally, open it in your IDE, ship it with EAS, or hand it to your team.
- One-click ZIP export of the complete source.
- Two-way GitHub sync: create a repo or link an existing one, push your changes and pull your team's commits. When both sides changed, you choose which wins.
- Works with Expo Go, EAS Build and every standard React Native tool.
- No vendor lock-in, no watermark, no runtime fees.

Start from anything
Describe it, upload an existing Expo project (.zip or folder), drop in screenshots or mockups, or upload a spec or PRD. The AI takes it from there.
Runs in your browser
A full Node.js runtime, npm and Metro run client-side. Nothing to install, and your code never waits on a build server.
Starter templates
Start blank or from a tabbed starter with Home, Profile and Settings, all wired to a shared theme and UI kit.
Terminal & problems panel
See install output, Metro logs and parsed build errors with file and line, plus a one-click “Fix with AI”.
Project-aware context
The agent searches your code, reads config and dependencies, and follows your existing patterns instead of inventing new ones.
Saved to your account
Sign in with Google, GitHub or email. Projects and chat history autosave, so you can pick up on any device.
Open preview full-size
Pop the running app into its own window to test at desktop size or share your screen in a review.
Where we're headed next
We ship fast. Here's what's coming to take your app from preview to the App Store and Google Play.
Native builds with EAS
Produce signed iOS and Android builds ready for the stores.
