Works like a stopwatch, only counts your steps, a StepWatch! Use it when you start a walk/run to see how many steps you took, no more having to remember how many steps you had at the start of your activity, then having to do the math in your head!
Simply press start and it will start counting your steps at that point. When you hit pause, it will stop counting, It will not count the steps you take when it is paused. You can hit start again to resume counting from the previous count. This has no effect on your total steps for the day maintained by FitBit. Results may not be accurate if used around midnight when FitBit resets the daily step count.
This basic free version only counts steps, and it also shows the time.
