Why can't you import an app to connect iq?

I recently got my first garmin watch and I am frustrated by the "customization". It is extremely limited and the watch faces that are available are terrible!  If you import the app "watch maker" from the app store, people can truly customize and create their own watch face!  Garmin "face it", it's a complete joke and shouldn't even be a thing with how limited it is. You want people to stop complaining that garmin watch faces are garbage, import "watch maker", and everyone will be happy.
