WordPress smartphone redirect shortcode is the only shortcode that will redirect users to their own stores when they are from a smartphone
You can see it in action here on this site. The idea is very simple: IF a user go to a page he will be redirected on to the relative app store.
Simply in your page/post white this code
[mobile_store_redirect play_store="urlOfYourMobileApp" apple_store="urlOnAppStore" windows_store="urlOnAppStore"]
