# Build your first app

> From idea to working app in one conversation

Pick an idea and describe it. The agent builds a working app from your first message.

<Tip>
  Start with a clear 1-3 sentence description. Be specific about the type: "mobile app for X" is different from "website for X."
</Tip>

## Describe what you want

Tell the agent what you're building. Write like you'd explain it to a friend.

```
Build a mobile app for my car detailing business. Customers can browse services,
see pricing, and book appointments.
```

The agent starts building immediately.

Your app is made up of a few building blocks. You don't need to know these upfront, the agent creates them as needed:

* [Web](/apps/web) pages or [mobile](/apps/mobile) screens your users see
* [AI](/apps/integrations) built into your app
* [Database](/apps/databases) to store your app's data
* [Sign up and login](/apps/auth) for your users
* [Backend](/apps/backend) for server logic, scheduled tasks, and API calls
* [Payments](/payments/stripe) to charge your users

## Refine the design

Once the foundation is there, iterate. Ask for visual changes the same way.

```
Use a chrome theme with muted blue tones
```

## Add features

Keep going. Each message builds on what's already there.

```
Let users upload photos of their car when they book
```

## Test it

Preview your app in the builder, or scan the QR code to test on your phone with [Expo Go](/apps/mobile/testing).
