The Myth of 10,000 Steps: A New Approach to Smartphone-based Health Apps for Supporting Physical Activity

This paper introduces an alternative approach to conventional pedometer apps which measure the wide-spread goal of 10,000 steps a day. Instead we focus on the intensity of physical activity, which is in line with recent recommendations of renowned health institutions such as the WHO. These promote a minimum of moderate to vigorous physically active time per week to achieve the desired health benefits. The paper discusses how the guidelines have been implemented. It also outlines how we help maintain user motivation over time (e.g. by integrating and personalising nudges) and how we intend to solve the challenges posed by different fitness levels and personal lifestyles.
