Huawei watch paired with Iphone

I just got a Hauwei watch. I paired it with my iPhone. I do not see the app on my watch despite it showing on Google play that it has been installed. how do I install facer on the watch??? and further. How do I get the faces on the watch??

I see there is facer for iOS, I installed on the phone, but it does not do anything.

I need help with this as well!
