I've read about calibrating the Apple Watch in terms of step count and I have done that, however, I've routinely noticed by step counts on Apple Watch are significantly lower than mine on the Fitbit Charge HR. I obviously don't expect them to match totally, but I've tracked them over last few days and the results are included below. What's interesting to note is that the total miles walked on both Apple Watch and the Charge are very very close. Any idea on what I need to do to my Apple Watch to get in more in line with the Charge? Thanks!
