Some of the initial problems with this app were simply growing pains which have since being corrected. I really love the app and both qardio devices including the blood pressure monitor and scale. The BP monitor works well with my Apple Watch. Both my wife and I can simply stand on the scale (separately) without tapping and will receive accurate readings which are immediately updated to the apps on each of our phones. The scale/app distinguishes who is on the scale at the time. I have to admit I was a bit frustrated for the first week or so after the scale was released but the support team was first class and all the problems seem to have evaporated. I am not sure I can justify the cost of the core product but I am very eager to hear how it integrates with the arm and base. All readings are uploading perfectly into Healthkit.
