4 stars: I do like that it gives a graph as well as the option of a 1min precision monitor. Do you think you could add an option to make comments on the graph before we save it? It would be really nice to make notes if I was laying down or out for a walk or taking laundry upstairs. Right now I have no way of knowing what was happening and my brain does not remember regular things never mind what I was doing at 4:43pm last wed. lol.
3 stars: anyone able to get normal readings? not sure his accurate this really is. first dot is ALWAYS Red. I am using an s9. I have had several abnormal ECG in dr office. not sure if that's just a coincidence or not.
5 stars: Better than ekgs (which last only seconds) this matches my AFib and HRates exactly, a split second behind my beating heart. Any irregularity I feel shows up on the screen immediately, mimicking my heartbeat exactly. If only it displayed in ekg format so that doctors would pay attention to it! Better than my 6Lead $160 Kardia which is delicate, difficult to use. Elec \
4 stars: excellent and quick way to determine both your pulse rate and your heart health. would give 5 stars if you are allowed to enter your age which is an important factor in overall determination. closely matches the EKG monitor at doctor's office. nice overall app for a quick insight but like with all applications that deal with health if readings vary need to always check with doctor.
5 stars: simple to use and understand. really good tool ...
