Development of an app for lung cancer survivors (iEXHALE) to increase exercise activity and improve symptoms of fatigue, breathlessness and depression

Exercise‐based self‐management interventions are recommended for lung cancer survivors and can provide physical, psychosocial and emotional relief. Mobile health technologies can encourage self‐management; however, currently, no cancer‐related app addresses exercise‐specific needs of lung cancer survivors. This paper details the design, development and testing of an exercise app for lung cancer survivors (iEXHALE), which aims to increase exercise activity and improve symptoms.
