I started Smart Linker because I kept seeing the same small but annoying problem around mobile app promotion. When a team wants to share an app, they usually have an App Store link, a Google Play link, and sometimes a website or
landing page for desktop visitors. That works inside a website where you can show buttons, but it is awkward for QR codes, printed materials, support replies, social posts, launch pages, and short messages.
The frustration was that the simple version of this problem should not require a large attribution platform, SDK integration, or custom routing logic. I wanted to create one stable public link that sends iPhone visitors to the App Store, Android visitors to Google Play, and everyone else to a web fallback. The other important part was editability, if the destination changes later, the shared link and
QR code should keep working. This felt like a small product, but a very real workflow problem.
