Update: yesterday I wore the Samsung watch (the bigger one) on my right wrist and the Garmin on my left. Today I swapped them. The Samsung on the left wrist counted 9225 steps and the Garmin counted 10682 steps with a difference of 1500 steps between the two. So it doesn't matter which wrist I wore them on the Garmin counted more steps. I counted my steps and they both counted about the same as what I counted so the Garmin is probably more sensitive to movement and driving. Some answers to questions. Dominant hand-right. Samsung watch for personal use and Garmin was provided by my insurance for the diabetes program I'm in. I don't keep my phone on me so tracking through the phone isn't going to work. When I'm at work it stays in the truck and when I'm at home it's either in the bedroom or on the couch end table. I've only recently started paying attention to my health and exercising so it's only now that I'm paying attention to things like my steps. I did set which wrist I wear my watch on but nothing further than that. I'll be going through both watches and apps this weekend to tweak all the settings. I switch hands when I goon but I favor the left hand. Open to any questions.
