# Mobile apps

GenVibe is one of the few AI builders that generates real **React Native + Expo** mobile apps — for iOS and Android — from a prompt. Preview them in a device frame in the workbench, or **scan a QR code to run the app on your own phone** while you build.

## Build a mobile app

Just say you want a mobile app in your prompt:

> Build a mobile habit tracker app. I can add habits, check them off each day, and see a streak counter. Use a clean mobile design with a bottom tab bar.

GenVibe scaffolds a React Native + Expo project and renders it in a phone frame so you can see exactly how it looks on a device.

## Preview in a device frame

On desktop, mobile projects show inside a phone mockup in the preview, so you can test taps, navigation, and layout as they'd appear on a real phone. On a phone or tablet the app fills the screen so you see it at true size.

## Run it on your real phone (QR code)

For the real thing, open the **QR code** in the preview toolbar and scan it with the **Expo Go** app (free on the App Store / Google Play). Your app opens on your actual device with live reload — changes you make in chat show up on your phone as you build. It's the fastest way to feel the real thing before you ship.

## Refine like any app

Iterate with chat:

> Add a settings screen accessible from the top-right gear icon.

> Make the tab bar icons filled when active.

## Get an installable app

When you're ready to put the app on a phone for real, click the **Android icon** in the preview toolbar and GenVibe builds you an installable **APK**, or an **AAB** for Google Play — no Android Studio, no command line. See [Android builds](/features/android-builds.md).

Because GenVibe generates a standard **Expo** project, you can also export the code (via GitHub) and run the build yourself if you prefer.

Mobile apps are available on the free tier — a great way to try GenVibe's standout feature.

## Tips

* Say "mobile app" explicitly in your first prompt so GenVibe scaffolds React Native rather than a web app.
* Describe navigation early ("bottom tabs", "a stack with a back button") — it shapes the whole structure.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.genvibe.pro/features/mobile-apps.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
