App install ads on print still work when the code is huge and the destination is a store listing, not a homepage. If you only have an iOS app, encode the App Store URL. If you support both phones, encode a small download page that offers two buttons - or sign up free and use a dynamic code you can retarget when the Android build ships.

FAQ: App Store QR Code Generator
Can one QR code detect iPhone vs Android?
The QR payload is just a URL. Detection happens on a webpage. Put a smart landing URL in the optional field (or as the main URL) so the page routes each device to the right store.
