If you want to get fit and be healthy, then you need to track your daily activities. Whether you do sports or exercise, or you are just trying to lose weight, you need to use the Stopwatch app to track and be more aware of the time you spend in each activity.

It’s not just a stopwatch. It is a perfect tool for tracking your workout, exercise, and for keeping a personal record of your health and fitness progress.
