O2 sensor: only nighttime average?

[Victamon]

Does the gauge for oxygen saturation only sample when the device presumes thay you're asleep? not during waking time, and no option for continuous? anyone know how often checks, orand how accurate it is?

And is its functionality in this regard the same as Fitbit's other devices that sense "SpO2"? (Which ones are these, anyhow?)

Hi @Victamon - the SpO2 is a one time average calculation overnight (with range) only for watches from Versa 2 onwards. No day or or on the spot checking available.

It also consumes more battery and can take a while to appear in the app as it has to be calculated offline.
