An app store download QR code generally refers to a QR code connected to a smart app download link. Which is a dynamic short link that simplifies the distribution and downloading of mobile apps. Instead of needing multiple download links or QR codes for your app, you only need one smart download short link (or QR code).
Onelink.to offers smart download links and QR codes with analytics. You add the download links to Google Play, Apple App Store, etc; and we make sure to send each user clicking the link (or scanning the QR code) to the correct app store depending on what device is being used.
