I was amazed after my first erg session wearing my new Galaxy Watch that it automatically recogonized that I had worked out on a rowing machine. Kudos to Samsung for this. As a rower, I am always looking for fitnesswear that recognizes our sport.
But surprise, surprise. Though the watch recognizes rowing machine workouts, it does not recognize on-water rowing. I can't figure out why. It seams to me it would simply be a matter of recognizing the same biometric and motion sensor indications, without (rowing machine) or with (rowing) indicated movement via GPS sensors. Then again, maybe I'm just doing something wrong (like not having my cell phone with me when I row), and if fixed it would recognize on-water rowing.
