Best fitbit for calorie and heart rate tracking?

[atticus05]

I’ve been searching for a more accurate tracker for the activities that I do - mostly spin classes and yoga.

I have a very old Charge 2 and it massively underestimates calories and heart rate. The other day it told me I burnt 200 kcal (it was more like 450) in a spin class and the heart rate didn’t go over 130 bpm (it definitely did). I don’t know if it’s because my fitbit is really old and potentially defective or are they all pretty bad at tracking accurately?

I read that apple Watches are a lot better but I don’t really want to part with so much money. I was looking at Fitbit Inspire 3 or 2 - would you say these would be any good for what I’m looking for? Or are there better options?

The charge 6 appears to currently have the best HR tracker in the range. I can say confidently it is much better than the Sense 2, especially at higher intensities.

Regarding calories, they're going to be tied to your HR tracking, and can only ever be a guide, but the better the HR tracking, the better your calorie tracking.

@Mcav75 not for everyone. For me, it trashes almost every single run. If HR is off (reporting between 190 and 200) then everything else is off. That didn't happen on any previous models I owned.
