Blood Oxygen Level Log | O2

The app isn’t accurate at all. The subscription is a scam because you can’t try the app before paying. I verified the results of the pulse with a known good device. The app was off by 20 BPM. The description leads you to believe that it reads the O2. It doesn’t.

This doesn’t take your blood oxygen I would like my money back. I’m very disappointed.

This does not work it will not give you a current oxygen reading

It would be nice if it would read blood oxygen as well

It just does 3 things: 1. pulls your oxygen and heart rate data from apple health and shows it to you (which you can already do in apple health) 2. Allows you to manually type in heart rate and oxygen data (which you can already do in apple health) 3 allows you to measure heartbeat using the iPhone camera app (which other apps do for free) So in sum. This is a total waste of storage space and no value to me. And it's a $10 subscription! Geez

Please tell me if I need to get or buy a blood oxygen test kit or can I measure it this way I have no idea .help me please?thanks

Very hard to understand how to measure blood oxygen levels. There’s not a test button for you to press. Sorry that I even bothered to download.
