First of all, i'm aware of the other threads about the same issue but i didn't find any serious answer from Fitbit and i would like to do my part too with opening another one and raise the issue.
Fitbit sense is my first fitbit wearable and also the first "serious" wearable.
Until i came here and saw all the threads related to the HR accuracy i didn't bother too much.
I was fine with Fitbit's automatic detection of my HIIT workouts.
When i started to record manually the workouts, as many others, i found the live HR absurdly wrong.
I bought also an optical HR sensor(Polar OH1) and seriously...what the **** is wrong with fitbit? How it's possible to have so much difference during workouts and keep everything so bad for months?
Heart rate during the day is really close between OH1 and Sense(2-3 bpm difference normally) but it's real s*** during workouts.
It's unbelievable that a company like Fitbit can release something like the Sense(Versa 3 too probably due to the same "improved" sensor/software?) without any update after 3-5 months?
Tell us something at least...i like the watch but if there's nothing new in the next month it will be the first and the last one from Fitbit, for me.
I will not post any comparison because there are enough of them in the other threads.
