AirSonea™ is the world’s first handheld device that turns your smartphone into a portable wheeze monitor. AirSonea isn’t a replacement for your doctor, but it is a portable, easy to use device that allows you to monitor wheeze symptoms anywhere and anytime.

By measuring the presence and duration of your wheezing, AirSonea can provide you with a percentage reflective of the severity of your airflow obstruction. You can check your WheezeRATE™, understand your symptoms, triggers and treatment, and then give accurate data to your doctor to help develop your asthma management plan.

If you have asthma or care for someone who does, you know it can be hard to stay on top of asthma management. AirSonea helps to provide you and your doctor with the resources you need to better manage asthma and live a healthy life.
