See your store's mobile app on a real device — before your customers do.

Mobile App Builder is the companion app for your Mobile App Builder workspace. Design your storefront in the admin panel, then scan a QR code to load it on your own phone exactly as a shopper would see it.

WHAT YOU CAN DO

• Connect in seconds
Scan the QR code in your admin panel and your phone links to your workspace. No usernames, no setup, no typing.

• Preview on a real device
Your screens, navigation, colours and branding render on real hardware — not a browser mock-up. See the actual spacing, the actual typography, the actual tap targets.

• Work across multiple apps
Save every app you connect to and switch between them whenever you like. Useful if you run more than one store, or manage several projects at once.

• Stay in sync
Pull down to refresh and pick up the latest changes from your admin. Adjust something on your desktop, refresh on your phone, see it immediately.

• Check it before you ship
Catch the layout that breaks on a narrow screen, the image that crops badly, the colour that fails in daylight — while it is still a draft.

HOW IT WORKS

1. Open your Mobile App Builder admin panel on your computer
2. Choose the app you want to preview
3. Scan the QR code shown on screen
4. Your app loads on your phone

That is the whole setup. The app remembers each workspace you connect to, so you only scan once per app.

WHO IT IS FOR

Store owners and teams who are building a mobile app for their storefront and want to see it on a phone before it goes live. If you are designing screens in the admin panel, this is how you check your work on real hardware.

REQUIREMENTS

• A Mobile App Builder account and access to the admin panel
• Camera permission, used only to scan the QR code that links your device
• An internet connection

This app is a companion tool. It does not work on its own — you need an existing workspace to connect to.

ABOUT PERMISSIONS

Camera access is requested for one purpose: reading the QR code that links this device to your workspace. Nothing is recorded, stored, or uploaded.
