So, I don't necessarily have an issue with my Active 2. Everything seems to work as it should without any problems. I always notice a discrepancy when I compare my workouts to my buddy with an Apple Watch. We do the exact same workout. We have the exact same body type. We always finish in about the same amount of time. Every time, my watch shows somewhere between 250 and 350 calories burned (all depending on the workout). His Apple Watch will show 600 - 700 calories burned. Why is there such a huge difference? Does the Active 2 only look at active calories where the Apple Watch looks at total calories???
