    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.

    Gyroscope and accelerometer. Presumably, it senses the motion of your body when you go from sitting to standing. How accurate it is will be interesting to find out. Especially when standing from a high chair like in your situation.

    People's heart rate rises when they move from sitting or laying to standing, so maybe that factors in? That would mean it's always tracking heart rate, though, which might be too large a battery drain.

    Probably as simple as the last time you took a certain number of steps. I'd bet it's more of a get up and move around than just a stand up and stretch and sit back down type of situation.

    Actually the stand ring is based of a continue 30 seconds of movement of the watch. Sometimes I've got up from my desk, walked to the kitchen, made a coffee and walked back to my desk and had my watch not detect it as a "stand" because at no point was there 30 seconds of continuous movement.

    It is also triggered automatically if you're recording an exercise (even if you're not moving)

    I find the stand ring somewhat erratic. I once got up at 6:15 am and spent the next hour + making muffins and walking back and forth in my kitchen, never once sitting down, and it did not recognize my standing, even though I should have gotten credit for two hours. It even tracked a few exercise minutes and active move calories in the same span, which I thought was really dumb. There is some element of urgency necessary to record the stand.

    Even today my watch skipped an hour that I know I stood.

    Agreed that the stand ring measurement can be erratic. I got credit while driving for several hours in traffic - my left arm was propped up on the window sill, during stop and go.

    That said, it mostly does a good job of knowing when you stand. You can have it poke you, or not.

    I have found that adjusting the angle of the watch can help. I have missed the stand goal with my arms hanging at my sides, but have earned it standing with my hand on my belt.

    You can continue to sit and swing your arms around for a minute and you’ll get credit for standing.

    does it track on absolute hours of the day? So between 5pm-6pm you need to move about a bit? Or is it relative based on when you first put the watch on in the morning?

    No, it’s each hour you need to indicate standing. If you haven’t by 10 minutes till the hour, you get a reminder. If you still don’t, you do not get that hour. You only need 12 per day.
