Smartphone app measuring night-time coughing ‘may help spot worsening asthma’

The research is to be presented at the European Respiratory Society International Congress (Yui Mok/PA)

A smartphone app which measures the night-time coughing of those with asthma could help predict when symptoms are getting worse, research suggests.

The study saw asthma patients sleep with a smartphone in their bedroom for 29 days with the app running in order to measure the noise of coughing during the night.
