Many watchfaces include some sort of display of steps and goal, be it in numbers, a percentage, or a bar/graph.
A couple of users I have commented that day-to-day steps/goal is meaningless, as some days they can't get out and miss goals, and other days, they blow past their goal by 9am. What they wanted was a "7 day" number of steps, so I added a "step/goal" mode, where it adds the previous 6 days of step history with the steps for today. (7 days)
Just something to consider in your watch face!
