I have a Samsung Galaxy watch and I am also a member of Weight Watchers. I absolutely love this watch, but I noticed its not compatible with weight watchers, or WW. I contacted them and asked why and they said both parties are working on it and it would be beneficial for me to ask about it with samsung as well. She said it was a commonly asked question. I have seen older posts about this and the responses were all the same but the issue was never answered. These posts are 6-12 months old and there is still no compatibility and no answers on if it is coming in the future.
