Asthma COPD

Take charge of your breathing


How Propeller works

Connect your medications

Propeller sensors attach to the inhalers you already have. The sensors automatically track where, when and how often you use your medication, and they send that information to an app on your phone.

Propeller learns about your breathing

Over time, the app learns about your flare-ups and medication use and can help you become an expert at managing your symptoms and identifying your triggers.

Work more closely with your doctor

Propeller creates reports that can help you and your family members to better understand your asthma or COPD, and to work with your physician to adjust your treatment plan as needed.

More than 100,000 people have trusted Propeller to help manage their asthma or COPD.

Many people experience fewer symptoms and flare-ups after just one month.
