I'm still having trouble with stairs I've started swinging my arm but it still doesn't seem to record but about half of them and I have stairs in my house

The watch doesn't really count stairs. It counts an ascent of 10 feet while you are taking steps. That is a stair for the watch. If your stair is very close to 10 feet it might not always count it as a stair.

Thanks.  I asked before and someone told me that if I swing my arm it helps.  I am also wondering if It helps to have the phone in my left hand.  Sometimes when I am walking up or down I hold onto the rail with my right and carry something in my left so it isn't moving.  Just trying to narrow it down.  Most stairs are 13 steps which is just a little over 8'.
