>I have to drop nearly dead and only then will I go to doctors' for diagnosis and treatment. This is a healthcare issue specific to your country. It is not a problem of "not enough measurements". Regarding using tech like smartwatches for blood pressure measurement, it is currently not possible. They aren't measuring your blood pressure, they are simply correlating optical data like pulse transit time with your blood pressure, which is mostly inaccurate. If you have to calibrate every now and then using actual bp measurements, then you already have enough data and don't need your smartwatch.
