COVID-19 Sounds App

Upload short recordings of cough and breathing and report symptoms to help researchers from the University of Cambridge detect if a person is suffering from COVID-19. Healthy and non-healthy participants welcome.


Volunteer your voice

The app will collect some voice samples (while you read text on the screen), and a few seconds of breathing and coughing.


Contribute to science

We need many participants in order to build predictive models and contribute to the early diagnosis of COVID-19.


No tracking

The app won't be tracking you and it will collect data when you actively interact with it.
