This pedometer slips around the neck under clothing (it is small and flat) gets into the trouser pocket, or bag and gives you the number of steps, meters traveled, calories lost, gives the time too.
It has a memory of 7 days to remember the steps taken / day.
Wait a few seconds after each stop so that it switches on again, but it recalculates same rate and therefore no you did not.
Do not hesitate, this is not a gimmick, it really boosts you to make better and walk a little more each day.
