I'm intrigued as to the accuracy of the 'calories burnt' section of the Samsung Health app.
Today I did a 10 mile walk. My Active Watch and Samsung Health app says I burnt 1900 calories. I was also wearing my Fitbit on this walk. It said I burnt about 1000 calories (which is in-line with what the internet says I should of burnt).
Which is more likely to be correct and why is there such a difference?
