Hi @miha21,

Any of the HR-enabled Fitbits will work fine. I like the Ionic and the Charge 2 personally.

Hmm... can't find any specs comparison. Regarding accuracy, are those changing from device to device? Do all the Fitbit devices have the same algorithm for measuring sleep quality etc? Not interested in design and other features, just looking for most accurate Fitbit sleep tracking device.

Hr enabled fitbits show sleep stages, non HR fitbits measure sleep quality. Which do you prefer?

[miha21]

Both... using Polar H10 right now but it's a bit uncomfortable to sleep with. I know I won't get the same hr accuracy with bracelet, but still looking for the best approximation with an addendum of actigraphy.

That's great. What I'm telling you, though, is you can't get "sleep quality" and "sleep stages" both--they are totally different things in the world of Fitbit. You have to choose, and the choice will greatly help you decide which model to get.

If you get an HR-enabled Fitbit, you can turn off HR when you want to see sleep quality, or leave it on when you want sleep stages. But it can't do both simultaneously.

All the Fitbits I've used are the same in terms of sleep accuracy. Fitbit doesn't advertise any of the models as being more accurate that way, so you're free to choose almost any of them.
