Breathcount is a tube-shaped medical device for lung state monitoring and prevention of asthma attacks. User blows into the tube and the information from device is sent via bluetooth to a mobile application, where it is personalised and converted to objective information about the state of lungs. The information can be immediately shared with doctors, parents or anyone user needs to inform. All the functions are tailored to meet the needs of people with asthma or COPD and their concerned parents who can receive a notification if the condition of their child is worsening.
