One of the major reasons I am upgrading from the Pebble is the built in fitness stuff. I know I need to stand more during my work day. I am just curious how it knows about standing time. Do we have to tell it we just stood up? I use a high stool at work and my head and hands are no higher when I stand versus sitting. Do we have slightly different blood pressure when standing? I hope that is not enough to change the heart rate. I DO want it to be automatic without having to tell it all the time. It would be great if I get credit for standing fairly regularly. Something like it knowing I did stand for a minute during the previous hour so it does not send me the reminder. PS: I DO know it is smart enough to know when we are getting our heart rate up to where we want and to track steps. Just curious how it know I stood up.
