With a QR code for app download you get a single QR code that directs users to download their app from various app stores, such as the Apple App Store, Google Play Store, or others. Instead of having separate QR codes for different platforms, a QR code for app download detects the user's device and directs them to the appropriate store for download.
Onelink.to is a service that offers QR codes and links for app download. This simplifies the process for users and ensures they are directed to the correct app store.
