How to Create a Smart App Store QR Code (Auto-Detect iOS & Android)

Printing separate QR codes for 'iOS App Store' and 'Google Play' clutters marketing flyers. A Smart App QR code uses browser user-agent detection to route users automatically.

How to Set Up Smart App Routing

  1. Create a lightweight redirect landing page on your website (e.g. https://yourdomain.com/app).
  2. Use client-side JavaScript to check navigator.userAgent: 
    if (/iPhone|iPad/i.test(navigator.userAgent)) { window.location = 'https://apps.apple.com/...'; } else { window.location = 'https://play.google.com/...'; }
  3. Generate a single lifetime free QR code pointing to your smart redirect URL.
