How to load your app

  1. Download Expo Go on your iPhone.
  2. Load your app in one of two ways:
    • In your project editor, find the QR code in the mobile preview area and scan it with your iPhone camera.
    • If prompted, open the project link in Expo Go.
  3. Any changes you make in the builder update in Expo Go automatically, so you can test iterations in real time.
  4. Test camera, location, notifications, and other device features directly on your iPhone.
Device features like camera, location, and barcode scanning won’t work in the web preview. Always test on your iPhone using Expo Go for full functionality.
