Stay away if you like to keep your health!
Using this app and iCare device from first day of development for 2 years already with honest believe it collects and shows correct data. Just few days ago find out by calibration it shows totally wrong figurs for blood pressure. Much lover that as it is! Which is very dangerous! It was showing 132-89 real one was 170-96 ! Even after calibration it keeps wrong outcome still today. Finally nice designed item but without the essential functions. It’s about humen health, please don’t bring any product on market before it’s 100% proven safe! I was one of the first supporter to develop this item and was nearly loosing my health!! Looking forward to receive helpful reaction of the developers.
