When I wear my sense to swim, it counts my calorie burn 50% less than my Apple Watch. For example, my sense will say I burned 150 calories and my apple watch will say I burned 300 calories for the same swim. How do I know which device is correct? I tend to believe the apple watch because I find it hard to believe that swimming for 35 minutes rigorously only burns 150 calories, but I’m not sure. Any feedback would be appreciated.
