Back to the Cloud for Awhile, Please!

Coinciding with Christmas and New Year's resolutions, I now have some old man problems because of lifestyle. I've bought into the new AppleHealth coordinated Life apps and am rather amazed at how simply monitoring one's lifestyle inspires healthy changes. Oximeter was purchased with me thinking that same level of excellence would be standard. Sadly, this app and/or the technology aren't as reliable. The pulse monitor is keenly accurate to my health charts. The O2 monitor just ... doesn't work. Error readings, suggestions to improve readings, online support--nothing seems to help to get it to work. I've tried sitting down, standing up, not pressing on the camera, and every lighting condition, but alas, half of my purchase is a dud. Boo. Maybe with updates I might get into it again, but I think I threw a fiver away. Sorry guys and ladies--I hate to write a downer review, but it is what it is. 2.5 stars. C-

Must do better

Having struggled to get app to work for some time I had given up using it. I downloaded latest version in hope of improvement. Now it does give BPM result, but no SPO2 at all! A good idea, but still no cigar.
