Monitor and track your COPD and asthma using your smartphone

The Global Asthma Report 2018 estimates that asthma affects around 339 million people globally, while The Global Burden of Disease Study reports that there were 251 million cases of chronic obstructive pulmonary disease (COPD) in 2016. Asthma and COPD cannot be cured; however appropriate management can help relieve symptoms, improve quality of life and reduce the risk of death.

ResApp has developed smartphone-based machine learning algorithms that have been found in a prospective clinical study to accurately identify acute exacerbations in patients with asthma or COPD. ResApp also has ongoing clinical programs investigating the use of these techniques to measure exacerbation severity and lung function.
