Introducing Ourbreeze . The first Asthma app that monitors multiple environmental indices, all of which can trigger or worsen symptoms in people with lung disease. You can easily input your Peak Flows/FEV1 through the phone app or your PC and track your numbers over time. Additionally, alerts can be set for all parameters, allowing the user to take precautionary measures to prevent potential flare ups.
Currently the app works in the US and the United Kingdom with more countries coming soon Check it out.
