Weather, pollen levels and pollution can wreak havoc on a person with asthma. But GlaxoSmithKline's MyAsthma app, available only in the U.K. so far, gives those suffering from the affliction the option to keep tabs on those elements and potentially take preventative measures. Patients signing up for the app take a 30-second questionnaire known as the Asthma Control Test to learn how well he or she is controlling his or her asthma.
Users can view real time data about elements that may trigger asthma. The app also includes an option to track how a user's asthma has progressed over the course of a month. An email will show results of the Asthma Control Test and MyAsthma Month chart, which users can then send to healthcare providers.
