Take charge of your breathing
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.
Propeller is easy to use and free if you qualify
We work with leading pharmaceutical companies, insurance plans and healthcare systems to offer Propeller at no cost to people with asthma or COPD. Answer a few quick questions about your medications, and we’ll recommend a sponsor for you.
