Background: Breathlessness is common through a range of chronic and life limiting diseases, such as chronic pulmonary disease and congestive hearth failure. There is a lack of knowledge concerning the understanding of the experience of breathlessness such as the relation between predicted, experienced and recalled breathlessness.
Method: Questions on breathlessness intensity will be asked to participants with breathlessness several times daily through a mobile application installed on the users own cellphone. The mean experienced breathlessness will be related to the predicted and the recalled breathlessness as well as to background factors.

Main cohort of patients meeting all of the eligibility criteria enrolled through newspaper adds, flyers and via non personal recruitment.
Smaller group of patients, meeting eligibility criteria for the main study, enrolled through clinical visits. These patients will be followed more closely and also be recorded in a logbook in order for later review. Some of the participants in this group will be interviewed in a semi-qualitative interview about their experiences of breathlessness.

- Multidimensional dyspnea profile (MDP) [ Time Frame: Up to one week. Starting from installation of application. ]Recording all dimensions of breathlessness
- Predicted intensity of breathlessness on a 0-10 numerical rating scale [ Time Frame: Up to one week. Starting from installation of application. ]Predicting future symptom level. 0 being no breathlessness and 10 being the worst imaginable breathlessness.
- Perceived self-efficacy regarding breathlessness [ Time Frame: Up to one week. Starting from installation of application. ]Rating on a 0-10 numerical rating scale. 0 being complete control of symptoms and 10 being the no control of symptoms..
