I'm having a quite annoying problem. My total calories burned are in my opinion way too low. I know for a fact that my BMR I about 1870 Cal, whilst in a day I clock around 600 Cal of activity, and still my total Cal is around 2200 Cal, so it basically doesn't add up. Is there any way to fix that up or is that just the way this app "works", because I bought the watch so it'll monitor my total Cal and I basically still have to do this myself... I would love any advice.
