The ‘Health Passport’ app enables you to put your personal asthma action plan directly onto your mobile phone, enabling you to track your symptoms, peak flow, and hospital visits. If your asthma is getting worse you spot it early and know when to seek help. In addition, the app integrates daily pollen counts, localised air pollution readings, and a weather tracker to enable you to identify external factors that may also contribute to your ill health, without you realising.
