Calories burned discrepancy between Apple Watch and Fitbit.

[Enbleu]

So My Apple Watch/ Health App says I burn 600 calories more a day than any of my Fitbit’s says I burn.

I have every type Apple Watch and every type FItbit that  has heartbeat monitoring. Always about 600 calories difference.

Why?

Hello @Enbleu, I hope you're doing well, it's nice to see you around. 

Please remember that Fitbit uses your BMR to estimate how many calories you burn through the day. Your BMR is determined by the settings you input about your height, weight, heart rate, age and gender. The Fitbit algorithms might differ from the ones used by Apple and if your settings are different on each platform that might explain the discrepancy. 

I hope this resolves your inquiry, if there's anything else I can do for you, please feel free to reply.

i have the same issue! i did a run ytd with both my fitbit surge and also my apple watch - one of each wrist.

the avg and max heart rate are close, but when it comes to total calories, my apple watch is abt 150 calories off compared to my fibit.

not sure which one is the accurate calories count

My Apple calories were always 300 calories higher than Fitbit. So I gave myself a sex change ( male to female) on Apple, and now the calories are more equal.
