The point is that if you check your blood oxygen level you might catch the problem before it is so bad that you have to be put on a ventilator and probably won’t survive.

I thought the burden of the Times article was that IF you are sick from a “cold”, don’t wait to test your O2 levels until you EXPERIENCE difficulty breathing, because by then it might be too late. Do you all have colds? I suppose, given that it takes Amazon six weeks to get one, you are wise to get a jump on it.

It's a lot easier to write the code, call it entertainment, and reap the ad revenues that to actually determine what the measurement means in the general population. Some apps have even added some of the other pulse oximeter functions, perfusion, respiratory pleth, Then, again, https://www.ncbi.nlm.nih.gov/pubmed/2921597 <https://www.ncbi.nlm.nih.gov/pubmed/2921597> says "Smartphone-based pulse oximetry is not inferior to standard pulse oximetry in pediatric patients without hypoxia. Reliability was superior for PBA compared with CBA, with more precise agreement for the PBA compared with the CBA. Future studies should test pulse oximetry apps in a hypoxic pediatric population." That was published in 2018.
