Garmin man me. Vivofit3.
I use it to cajole my lazy mind into doing my daily 4 miles. Which for me is just under 8k steps. I measured a two mile route from my house in the car and walked that route quite a few times in order to calibrate my step length.
I have now built up a discipline to do that walk and when I don't go on a walk in the countryside I tend to do that measured urban walk . I have to say that for me the step counter was my conscience and for a while my crutch, but no longer.
