Propeller Health is the doctor-recommended way to manage your asthma or COPD. Propeller makes it easy to stick to your treatment plan and helps you learn what may be causing your flare-ups so you can have more symptom-free days. Their sensors attach to the inhalers you already have, connect to the mobile apps, and track where, when, and how you use your medication. Over time, Propeller learns about your flare-ups and medication use so you can become an expert at managing your symptoms, identifying your triggers, and working closer with your doctor so you can continuously improve the management of your asthma and COPD.
