Quickstart
Go from idea to a working app on your phone in under 5 minutes.
Before you start
You'll need:
- A phone (iOS or Android)
- Expo Go installed on it — free from the App Store or Google Play
- An AppX account (free)
Step 1 — Sign up
Go to appx.uz and create a free account. No credit card required.
The Free plan gives you 100 credits a month to build and iterate. Generating a new screen costs 1 credit, and chat edits are metered by how much work they take — small tweaks are typically 1–3 credits. See Credits for the full breakdown.
Step 2 — Create a project
From the dashboard, click New Project and give it a name. The name is just for you — it won't appear in your app.
Step 3 — Describe your app
In the generation box, describe what you want. Be concrete about the screens and the key features:
Build a personal finance tracker with:
- A home screen showing this month's spending summary
- An add-transaction screen with a category picker
- A history screen with filters by month
- A clean dark theme
Click Generate. AppX plans the screens, then writes the React Native code for each one. You're charged 1 credit per screen — and any screen that fails to generate is automatically refunded, so you only pay for screens that land.
Step 4 — Preview on your phone
When generation finishes (usually within a minute), a QR code appears in the preview panel.
- Open Expo Go on your phone
- Tap Scan QR Code (iOS users can also scan with the Camera app)
- Point it at the QR code on screen
Your app opens on your phone in seconds. Tap through it exactly as your users would.
Keep the app open in Expo Go while you work. Every edit you make in AppX pushes to your phone live — no rescanning, no rebuilding.
Step 5 — Make a change
Open the chat panel and describe what you want changed:
Make the home screen background a deep navy, and bump the balance
number up to a large bold heading.
AppX reads your current code, applies the edit, and updates the preview on your phone. Reading code, previewing, and chatting are free — you're only charged when an edit actually changes your app, and retries within the same edit are free. Don't like the result? Just ask again.
