Blood Oxygen Saturation not Accurate – SleepOn Review

Compared to my medical grade pulse oximeter that is FDA approved this device is off by 5-12%. If not fixed this makes Go2Sleep totally ineffective. Please improve its accuracy because it has great potential. Lot of very sketchy reviews listed here. September 2018 Update: Blood oxygen measurement is over 10 points off and is medically dangerous it is so misleading. REM sleep is not being detected at all. When I use the restroom at night these instances are not being captured as awake time. They make empty promises to fix things and ask for patience...really??? Beware all the FAKE reviews here in the App Store. Piece of junk as far as I am concerned.
