Stay away from the Samsung Gear Fit 2. I have one, and using it as a connected device, counting steps is fine. But as far fitness tracking it sucks. It has an "auto detect workout" feature. I have been on my lawnmower drinking a beer and it will detect bicycling. I have been on 40 mile bike rides and it never detected the ride. I was also using it when I first started riding my trainer last winter. It would tell me that I was at my resting HR for 30-35 minutes of the ride, then out of nowhere it would start tracking my actual HR. I have tried to live with it and deal with the issues. But now I mainly use it as a connected device for my phone.
