Estimated Oxygen Variation graph is broken

[AndreaVersa2can]

Hi, I just noticed that the green and yellow lines have changed and now are all over the place on the graph. All graphs for different days start with a 0:00 hrs. The fluctuations are not at all in line with what I was reading up until today.  Anyone experienced this issue?? Thanks

This has been addressed in other posts, there has been a change in granularity of the data as well as presentation which people are finding very unhelpful.

Hi, so is the graph correct and more accurate that earlier? Is there any communication from Fitbit that says so?

There was some response that said it was an error and Fitbit was working on it.

Everything is just a mess😏

They say no publicity is bad publicity. Google/Fitbit could have handled this the way any software developer would have: after noting the bugs just say "Oops, this update not ready yet...", revert to previous version and work on a bug-free update for later release. That they did not do this has caused the furor we are seeing. And it makes one wonder if there is not something in the update that adds value to the app for Google/Fitbit, such as harvesting more and/or more useful user information. That would make them loath to roll back to the older release.

I have an Android phone and I believe it's specifically related to the Android app. Customer service told me that they notified customers at the update. Not true. Now this is completely unusable. Customer service said that they changed the formula. Most days it shows my oxygen variation levels at alarmingly high levels. Also some days show a flat line for certain times during the night. I have asked my wife and she said I don't snore. What could this be?

What's more, look at your history go back months and years, all of the previous data has changed and they don't even give you the year that you're looking at. If I go back to where I scroll somewhere into 2020 or 2019, I see a date range but no year. I can't tell if if it is truly showing 2020 or 2019. Why would they not show the year?

Omg I am so glad I found this forum. I was panicking when I saw my crazy chart today.

Hello. I just did the newest update and my graphs still look crazy and erratic. I absolutely never had one that looked like this before I downloaded the the update for the oxygen data less than a week ago. Will this be corrected going forward since I downloaded this update? Thanks

I use a CPAP configured after an actual sleep study. So to see this is very disturbing especially if it's a Fitbit error. Again sleep is why I bought the Fitbit.

I'm glad they're working on a fix. Here's a screenshot of the same time period using an iPhone vs Android.

--update 8/18/22: it's been fixed. Thank you!

Mine is doing this also.  Why do you suppose they changed all the earlier tracks too?

[Skoobie72799]

Excellent point!!! 

[SunsetRunner]

All the data that have been collected are displayed the same way by the app. This is due to the app update, not the firmware update. The new data presentation is worthless but so was the old one, for one reason, the axes are not labeled. Without a label on the Y axis you do not know what the data represent. As it is now, they are only colors, with scary yellow to show that "something bad is happening." For people with sleep apnea the new presentation is disastrous and should be ignored completely simply because it causes mental distress.

[SunsetRunner]

The new graph is not more accurate, only more granular, which by definition means it's probably less accurate in terms of how we read it. The big change means there is no longer a smooth curve which was easily mentally overlaid with the sleep data graph. This is a big failure.

Cpor, your first point about Android only EOV problem has been mentioned before but I've not seen anyone mention about the missing YEAR on the new graphs and I've also noticed that ambiguity.  We should probably state it in a new thread since it's not specifically about the EOV graph but rather, a bug of the New Graphic interface.

It appears the Chinese government has taken that site down.

The previous presentation demonstrated whether or not your oxygen variation was low (green) or high (yellow) and when. Mine was consistently in the low range. Now, it shows the same color variations, but 50% of the time it claims my variations were high (yellow). That's not the same data being presented differently. It's completely different data.

[Shivparsh]

If it's more granular, then I would say it reveals something that was 'hidden' so far. And so it should be deemed more accurate, am I right?

Fitbit needs to answer what has changed and whether this is a bug or an improvement. Is there any communication anyone is aware of?

[SigHillDude]

A very interesting read. Unfortunately the author misses the point that Fitbit is NOT giving data in the Oxygen chart.  It isn't clear exactly what they are giving.  Now that they provide an average SpO2 overnight, one has to ask exactly what the chart actually means.  As SpO2 can not exceed 100% and rarely is that high anyway, what does high variation mean?  As I can't compare with daily awake values, how can I assess whether nighttime values are any different. And what exactly is high variation with 95% SpO2 and the device unable to read below 80%.  I know awake I vary below 90% so it has nothing to do with apnea nor any health concerns.  It is called a meditative state. 

[SigHillDude]

Strongly agree.  There is a lot of issues with the information reported by the device and the way Fitbit manipulates the data is highly questionable.

Look at the header in the web app, not on the actual page.
