Further, elements such as challenges, badges, or rank lists with family, friends, or a community are used to motivate the users of an activity tracker to perform a healthy amount of daily physical activity.
By documenting and defining a certain daily goal in this manner, the user is encouraged to reconsider his or her lifestyle and incorporate more physical activity into their everyday life. Recent attempts to encourage individuals to perform physical activity include activity trackers and fitness apps, which have turned mobile phones into a personal measuring instrument to document daily physical activity. Thus, solutions for motivating individuals to perform physical activity on a daily basis are more essential than ever. As a result, health care costs rise, and the probability of secondary diseases such as high blood pressure rises, too. In 2016, more than half of the entire German population performed an inadequate amount of physical activity per day. In Germany, physical activity is continually decreasing within the population. Although organizations such as the World Health Organization constantly promote the value of physical activity, the trend is the opposite. Daily physical activity is one of the leading strategies for fighting global mortality.
