What Is Self-tracking All about Perhaps you've tracked  how many kilometers you've run, how many hours you've slept or how much you've eaten in a day. If so, you've taken part in a popular movement called the "Quantified Self Movement" or "Self-tracking". Maybe you've wanted to change a bad habit but couldn't. Self-tracking may be your answer. The idea is to collect information about your everyday activities and analyze  them to help improve and form a healthier lifestyle. Recently, tools such as smartphones, apps, along with newly published wearable things, are making self-tracking easy. Today, one can use Fitbit, the Jawbone Up, Google Glass or a smart watch to record personal data  including sleeping hours, stress levels, heart rate and mood. So why does a person self-track?
