Calorie count : FT7 vs Walkmeter .. And the winner is ...

Just got my self a polar FT7 HRM and went out for a 13km walk
I was shocked to see the difference in reported calorie loss between the 2
My iphone reported 1064 whereas the FT7 reported 908 :tongue:
So I think that the FT7 is a worthy investment, happy days :laugh:
