App Download
Create a QR code that detects the scanner's device and sends iOS users to the App Store and Android users to the Play Store.
What is It?
The App Download CTA creates a single QR code that intelligently detects whether the scanner is using an iPhone or an Android device, and redirects them to the correct app store automatically:
- iPhone users → Apple App Store
- Android users → Google Play Store
This eliminates the need to manage separate QR codes for each platform.
When to Use It
App launch campaigns
In-store or physical marketing for apps
Product packaging directing users to a companion app
Events where an app is required for check-in or content
How to Set It Up
Select 'App Download'
Choose App Download from the CTA type list.
Enter the App Store URL
Paste the full iOS App Store link for your app (e.g. https://apps.apple.com/app/yourapp/id123456789).
Enter the Play Store URL
Paste the full Google Play Store link for your app (e.g. https://play.google.com/store/apps/details?id=com.yourapp).
Set a fallback URL (optional)
If the device cannot be identified as iOS or Android (e.g. desktop browser), enter a fallback URL — typically your app's marketing website.
Save and test
Test on both an iPhone and an Android phone to verify each is routed to the correct store.
How Device Detection Works
SMLLR reads the User-Agent string sent by the scanner's browser to identify the device OS. This detection is highly accurate for modern devices. Older or non-standard browsers may occasionally fall through to the fallback URL.
