Estimated Oxygen Variation

[Den_in_USA]

Why is this now available on only some Charge 3 and Versas?

Pbug,.

Excellent summary. Thanks for taking the time. 

Seems these forums serve a useful purpose, but also. Act as a forum to  rationalize poor design and misleading advertising.

Unfortunately it does I think if fitbit would give a positive reply to any questions or just tell it how it is be helpfull

Perhaps you'd like to rewrite your comments with punctuation plus an
explanation of what a finger probe is.

I would note;

1. Finger clips can give very different readings depending on how they rest
on your finger, how clean they are, and battery condition.
2. It's likely common that a finger clip and Fitbit give SOMEWHAT different
readings - they take their readings at different points Also, one is real
time, the other is some unknown form of overnight average. One of my
suggestions to Fitbit on asking for real time SPO2 readings is to provide a
way, on one's phone app, to calibrate it against a known, accurate finger
clip.

[Tracy7873]

Apologies about my grammar,won't happen again.I agree with you about the separate app and the finger **ahem** as that's exactly how mine works,it collaborates with an app through bluetooth everytime I use it recording my results .

What I meant about calibration was being able to calibrate your Fitbit
against a known, accurate pulse oximeter. For instance, I've compared my
pulse oximeter to medical grade units on several occasions so I believe it
to be accurate. Now if Fitbit provided a realtime (perhaps once every few
seconds, frequency based on needs), I'd want to calibrate my Fitbit against
my know pulse oximeter (with an adjustment done within the phone app). In
general, while the Fitbit does get a bit strange at times when measuring
Heart Rate, it usually does match up against my Pulse Oximeter.

[Tracy7873]

I agree totally with you , can't honestly see fitbit doing this to be honest .

C Hutton

[pbug56]

Agreed, but we've no idea why Fitbit won't let us use realtime SPO2, let
alone why they won't tell us why. The feature is more and more common from
other vendors.

[Tracy7873]

Maybe if we got everyone that uses the app to sign like a petition for one they might listen.

Fitbit doesn't seem to care what its customers think about SPO2 readings;
many have complained.

Please remember that this is the community board, where the community of fitbit users can discuss and help each other. If you are looking for an answer from fitbit, it may be best to contact fitbit. 

If you have a suggestion for fitbit, then we have the feature suggestion board. 

[pbug56]

The suggestions on this appear to have been ignored. For years.

[Tracy7873]

I actually feel like they don't care about anything .

How much of the oxygen details are made available based on locating of the owner? If I live in the USA, do I not get a lot of the oxygen features,  like clock face? I get that it consumes some battery, but that's fine. 

Let me know!!

[Tracy7873]

It shouldn't matter where you live you should still get everything as for the clock faces you have yo download then yourself

C Hutton

[Rich_Laue]

As for clock faces, try these, I count 12, but I do not know how many require premium. 

Also make sure that SpO2 app is installed 

[Dopovo]

You count wrong @Rich_Laue , they are 9. Just to clarify, no independent developer can add SpO2 in their clockface / app because there is not such API provided by Fitbit.

[pbug56]

Reminder - SPO2 readings on any Fitbit out that I've heard of are limited
to some sort of overnight average while sleeping. Plus there;'s a mystery
'variance' chart in the phone app. Fitbit does not provide an API to allow
any app to use the sensor in real time / on demand. No reason has ever
been provided for not. There is heavy demand - and at least some Fitbit
users have switched over to other brands that offer it.

[Westerj]

This.  If data is not reliable, perhaps fitbit will find more blood on the inside surface of the wrist, than on the outside? But that is both arterial and venous in close proximity.  A detector by the clasp might be more useful?  Love the comment about API.  Whose information is this anyways?

[Rich_Laue]

@pbug56 I can give a good reason that the API can not get real time data. 

The API allows third parties to have access to Fitbit's cloud services. Therefore the API can only access your data after a sync. 

Your tracker also does not have a permanent connection to the Internet. 

Some have the sensors can have linmited access from an app on the watch. 

Fitbit also has closed the watch connection with third party devices. 

[pbug56]

First, real time or on demand of SPO2 displayed and recorded on the S1 and
other watches does not need the internet, nor does it use any 3rd party
apps.
Second, Sense 1 is not downgraded like Sense 2 is - you can use 3rd party
apps on it.

Third, the overnight mystery SPO2 variance chart could be a real O2 level
chart by getting data when you sync up. And that data should be
downloadable just like HR, etc.
Fourth, S1 can get internet data, potentially via your phone, such as the
weather.
And a reminder, all sorts of other fitness watches now do real time or on
demand SPO2. Several fitbit models old and new have the sensor, store the
data, feed it to TODAY's sleep SPO2 readout on the watch, or on some watch
faces, and feed something from it to the mystery variance chart.
