It’s a good app for a good device except for the BP graph. Unfortunately the scale for the graph is by 50: ie it goes by 50,100,150 and 200. It makes reading difficult. I wish they have markings by 20 instead, ie, 60,80,100,120,140,160,180. This will sync very nicely with the bands for healthy, borderline, high BP which will make reading a lot more easily and logical.
