Let me start off by saying the app works fine on my android phone. The app description it indicates that it also supports smart watches, yet nobody can tell me how to enable this feature on my watch. I have a galaxy watch 4. The simple question is, does it work on the galaxy watch 4? If it does, how do I get it to work? If it doesn't, then let me know. My low review is only because I have tried Bluelink support, and they don't have a clue. Otherwise, the app does what is described.
