Samsung Galaxy S3 Watch??

I have a S3 Samsung Galaxy Smart watch and have a question.. Hopefully you can answer my question.. I am an avid sports fan and would like to change the watch faces as the sports seasons change.. To do this, it seems as though I have to purchase and download the "Watchmaker" android app for my phone to apply various faces on my watch. Anyone have any experience with the Watchmaker App and is it worth it??
