I use my Fitbit charge 2 when I cycle but map my ride using Strava.
When I finish, my burned calories are different in each app. My Fitbit gives me calories based on my heart rate and length of time cycling and strava uses time/speed and distance.
Which do do you think is more accurate? (I can't rely on the GPS on my charge 2 as it's often spotty and I lose blue tooth connection and when I sync strava to Fitbit I get a duplicate ride recorded on my app...) The two calorie counts are significantly different - Fitbit nearly doubles what strava gives me...
