Which fitbit is best/most accurate for sleep tracking?

[Aliciao1]

Does the sleep tracking technology differ between the fitbit versions that offer sleep stages? For example, is the Charge 3's technology somehow more advanced or better than that of the Alta HR or Inspire HR? Thanks!

Hi @Aliciao1,

As far as I know, all the HR-enabled fitbits use the same PurePulse technology. It makes sense they would track the same, so that results are consistent when we switch to another fitbit.

People may have different opinions based on their experience (that Versa is better than Alta HR or vice versa). But between the Charge 2, Alta HR, Charge 3, Ionic and Versa--I've noticed no real difference.
