How to view oxygen variation in percentage?

[Rhianna4321]

I can see my oxygen variation graph however I can’t see any percentage which makes it hard to keep track. Where can I view this? I have a versa 2. It is showing my oxygen variation is low but without a percentage I don’t know how worried I should be..

Hello @Rhianna4321 

This help page explains the Fitbit oxygen variation tracking (<-- click link)

Just to let you know, there aren't any units of measure for that graph's X or Y axis.

@Rhianna4321   As you probable know, Versa 2 users need one of the Fitbit SpO2 clock faces for the feature to work.  The linked page shows third party faces, but you must use a Fitbit clock face.  All the Fitbit clock faces show your range.  The clock face range makes a lot more sense than the EOV graph.

This is my explanation of how this all came to be, with some personal observations included.  Measuring and reporting an SpO2 value is a medically regulated feature.  It needs FDA approval.  Fitbit released the EOV graph in February 2020, when the wearable market was racing to be the first to have this feature.  Fitbit couldn't put numbers on the y-axis, because it didn't have FDA approval this feature.  Fitbit released the SpO2 app and clock faces later, in September 2020.  Fitbit had to put the time, effort, and money to get that FDA approval for the SpO2 app and clock faces.  Opinion -- Fitbit seems to add on new features, but doesn't go back and update older features.  Does this make sense?

Ah yes this makes sense, thank you so much for your explanation. I have now set up the clock face and can see the percentage there. I will just ignore the graph as it informs me that I’m low without any information, however my percentage seems to be within normal range.
Thanks again
