SpO2 app is installed but Fitbit app doesn't find it

[Jaelkay]

Since the last App update (5 days ago), my Charge 6 is not recording SPO2. 

I have restarted my FitBit, but the problem continues.

Try reading the whole thread buddy. "did they ever?" when people are reporting problems over the last couple days, along with the last few months.

yeah, they ever fixed it for sure!

This has been an ongoing issue since around April 2025 after I updated the app. I have had several tech think they resolved the issue but still a problem. They also keep saying keep checking and doing all the updates and the problem should resolve but still is not.

Thanks buddy

SpO2 reading is delayed by up to 24 hours, so if you scroll back to
'Yesterday' on the app homepage it should be there under Health Metrics.
Apparently Google has stated that this reading is now 'delayed'. Not sure
why the change, maybe they found a cheaper provider of this data analysis?
Who knows. One thing is clear, it won't be 'fixed' any time soon!

You're absolutely right—re-adding the Charge 6 can trigger a partial reset, which might explain why it behaved like a new device. Fitbit really needs to streamline their update rollout and clarify what’s considered a regulated health metric. The SpO2 issue especially shouldn’t be this vague.

On a side note, during all this syncing trouble I found myself relying more on lightweight apps for everything—including streaming. If anyone else needs something fast and frustration-free, the best streaming app  has been a solid fallback lately. No account needed and just works.

Thank you very much for the information.
I can now stop wasting time trying to solve it.
Thanks

This happening again. Was there another update that caused the Sp02 to not work again?

Hi @GinNjuice and welcome to the forums. 

Thank you for your message. I'm sorry to hear that you are experiencing again the SpO2 issue. 

Could you please confirm if there is an available update for your Fitbit device? How do I update my Fitbit device?

[Jayes249]

I think I have the most recent version (4.50). From what I can gather from
Google support, SpO2 readings are now 'delayed', appearing around 24 hours
later. This seems to be the new normal. Better than none at all, I guess 🙄

I haven't even gotten that the last two days

[Jayarrh]

I have given Fitbit away, bought a Samsug instead, no problems now!

I have the exact same problem with my Fitbit Sense 1.  I just got the watch on Amazon and spent two weeks trying to get it to give me overnight O2 data.  It says I need to "install the SpO2 app" but when I click on it, the app is installed.  I've removed and reinstalled the App and every other fix I could find on Google but no luck.   The main reason I got this watch is for the overnight O2 recording.  It looks like my best option is to return it to Amazon and try a different brand.

For me, the issue has been going on for a year, so....

I have discovered that my SpO2 readings are often delayed by many minutes
and sometimes many hours. Check by going back to the previous day(s). I
still frequently get spurious SpO2 App needs installing messages.
