I finally found a device that accurately counts my swimming lengths AND analyzes my strokes...Samsung GearFit2 Pro. I used a Fitbit and would receive 10 pts. a day when I used it during my practice. Now I'm only getting a few points. The Gear Fit2 also records my heart rate. I am linking the Samsung Health to my Go365 account. Any suggestions? I swim anywhere from 2500 yards to 3500 meters and it takes about 75 minutes to complete. It more than enough meets requirements for a good workout.
