Why do the total calories burned differ between Fitbit and Cronometer?

keepthebeet

It's just after 10pm. Fitibit says I've burned 1,991 calories today, and Cronometer says 2,047.

My weight is the same in both. I have Cronometer set to 'no activity' above BMR - and based on what I've read Cronometer somehow only adds 'calories burned' from Fitbit that are above my BMR.

One guess is that Cronometer is already guestimating my calories for the whole day, and that Fitbit will make up the difference by midnight. Is this correct? Both are set to the same time zone.

A central FAQ clarifying info like this would be greatly appreciated!

Hello @keepthebeet

You got it! Fitbit gives you your total calories up until right now, while Cronometer gives you your total for the day so you can plan your meals accordingly.

Best,
