This should be implemented a long time ago. As an Android and iOS user, one of the things I hate the most is that iOS app discovery on web clients is really painful. Sometimes I click on a link and it opens me iTunes (SHUT THAT WINDOW PLEASE!), sometimes I’m able to see the app page online but always have to open the AppStore and search for the app and install it. Google Play has this figured out for years now and it works really well! And the solution you’re showcasing here looks perfect. Just need to figure how it’ll work if you have more than one iOS device.
