Aerlink Wear Connect for iOS is not installing on Sony smartwatch 2

I bought Sony Smartwatch 2 and successfully paired it with Moto X Play using Sony "SmartConnect" and installed applications like Gmail, etc... Now I'm trying to pair it with my IPhone 5s. For that I need to install "Aerlink Wear Connect for iOS" application. But when I try to install this application it is installing in my Moto X mobile but not in SmartWatch. How to install "Aerlink Wear Connect for iOS" application in my Smart Watch 2?
