Hello Nathdube62,  

Welcome to the Apple Support Communities.  

Try checking the App Store for your Apple Watch. If an app is available, you should be able to find it in the App Store.

If you are unable to find a version of an app available for Apple Watch, you can contact the app developer for more help: How to contact an app developer - Apple Support

All the best!
