Dangerous Garbage


“For recreational use only”? I was hoping to perhaps use this as a “general idea” tool so I wouldn’t have to carry my pulse oximiter around with all the other junk I have to carry with me.
This thing is BEYOND off base and is dangerous. After doing housework, this thing says 96% / 105. My regular pulse oximeter? 82% / 123. Not EVEN close. I’d like to have my money back, please. I thought by paying some $ I’d get some quality. Nope.

Worthless and harmful

Heart Attack 1107

I had a heart attack 6 weeks ago and am constantly monitored during cardiac rehabilitation 3 times a week. I purchased this "free " app for my new iPhone to use at home. I took it to my cardiac rehab to check its accuracy against the hospital monitors. When the hospital monitor read 114 for my pulse the app read 58!!! I repeated this five times with the same results. Worthless!!!

Pulse works, O2 sensor is garbage


So, I've been using this app for several months now. I was always suspect of the 02 sensor and how accurate it was. I compared it with an O2 sensor that is used by medical professionals and this app is garbage.

However if you want to just measure your pulse, this works pretty well.
