Blood Oxygen Level

I have several ways to keep track of my daytime Spo2. What this one could use is a place for a note with each entry. It's important that I keep track of conditions related to each reading.

It would help to have instructions on using app.

Very simple and easy interface, straightforward. You do need an external device (watch/pulse ox) to read those stats and input manually (ie doesn’t connect to anything via bluetooth or sync with an app, if that’s what you’re looking for). I wish there was a way to “purchase” a subscription to be ad-free. On my device there so far was one full screen ad to x out of and a constant small box ad along the bottom of my screen. The addition of a small notes section with each logging would be nice. I’d like to note if who I was tracking had just had a nebulizer treatment, or was on any amount of supplemental oxygen, or asleep, etc when logging the information. The addition of that would guarantee a 5 star rating from me. Also, the main screen for this Shows your “average” for all logged O2 and pulse. Not your most recent readings/logged. Not a problem for me, as I’m strictly using this to log/record sats from through out the day.
