SPO2 on Sense.

[dakfenor]

Good morning.
Please I would like two clarifications, I am a Versa 2 owner and I would like to switch to Sense but I have two big doubts.
I downloaded 3 days. makes the SPO2 app, the dial that allows the measurement of oxygen in the blood.
Well I found that the measurement only takes place at rest!
This is because the sensor must have at least 3 hours (!) Of time to take an accurate measurement ...
But does the measurement instead of SPO2 on the new Fitbit Sense happen the same way?
That is, only at rest and after at least 3 hours of sleep or does it perform a faster measurement even when "awake" with a special ad hoc sensor?
Furthermore, the ECG measurement, always on the new Sense, also occurs at rest, sleeping, or can a measurement be made instantly, in a few seconds, and at any time?
I would like to buy the new Sense but I am blocked by these two things, none that can be clear, the competition, without naming names, has managed to launch smartwatches that perform, through ad hoc sensors, the measurement of oxygen in 15 seconds, both awake and not, and a one-lead ECG measurement in moments.
Without making comparisons, the new Sense is not cheap, if I have to buy a watch that makes me the SPO2 only while sleeping and in 3 hours like my Versa 2 does then I honestly don't see the usefulness.

Hi @dakfenor, great to see you in the community.

The SpO2 measurement on the Sense is the same as your Versa 2, being that it is only taken during sleep. There currently isn't any way to perform an on demand reading. 

The ECG however is an on demand process. You will need to open the ECG app and then place your thumb and forefinger on the corners of the device for it to take the reading.

You can vote here for on demand SP02 readings: https://community.fitbit.com/t5/Feature-Suggestions/Check-my-Sp02-pulse-ox-at-anytime-on-supported-F.... I created the post yesterday because I couldn't find a similar feature request already. So far this is the 1 thing that I don't like about the Sense. Hopefully Fitbit can add this soon too.

I have a $20 SpO2 monitor that clips onto a finger and gives instant readings.

This doesn't seem that hard.

This $330 watch with an SpO2 sensor in it should handle that. This is ridiculous.

There is no ECG app?
