Your site as a mobile app

Every site you build is also a phone app — automatically. Nothing to configure, nothing to submit anywhere: your visitors scan a QR code and your site opens as a native app on their phone, with the same live data as the web version.

How visitors open it

  1. They install Expo Go — a free app that hosts apps like yours, straight from the App Store (iPhone / iPad) or Google Play (Android).
  2. They scan your site's visitor QR code.
  3. Your app opens. Next time it's in their Expo Go like any installed app.

Expo Go is a standard, widely-used app-launcher — think of it as a browser for native apps.

Where the QR codes are

Two places, same codes:

  • Dashboard → your project's page → Open mobile app.
  • Your site's admin panel → the Phone page — with per-phone install instructions you can point people to.

There are two QR codes: the visitor code (share this one — it's stable, print it if you like) and an admin code just for you, which opens the app already signed in as the owner. Because anyone who scans the admin code gets admin access, it stays hidden behind a "Show QR code" button — reveal it only when nobody else can see your screen. Revealing always issues a fresh code; each code works once and expires after a few minutes.

Already reading this on your phone? No second device needed — both pages have an "Open on this phone" button that opens the app directly, plus a copy button so you can send the link to anyone.

Good to know

  • It's the same site. Changes you make through the AI Builder appear in the app immediately — there's no separate "app version" to maintain.
  • Your own domain carries over. If you've connected a custom domain, the QR codes and app links use it.
  • Phone-friendliness is part of building. Sites are built to work on small screens from the start — but if a page feels cramped on a phone, tell the AI Builder like you would any other issue.
  • The app store route exists too. If you eventually want a standalone app under your own name in the App Store / Play Store, that's done by exporting your project — the export guide covers store builds.
