Wing is a novel, pocket-sized sensor designed to help people manage their asthma. Featuring what its maker Spare Labs says is “medical-grade accuracy,” the device has been launched on crowdfunding website Indiegogo, with the goal of raising $50,000 in a month-long campaign. A single device is pre-selling for $99, which is 33% off its retail price.

“We designed Wing to help give peace of mind to people suffering from respiratory conditions like asthma, CF and COPD,” Co-founder Abby Cohen said. “Not only does Wing help people better understand their lungs and manage their condition, but it also helps their physicians identify the treatment plan that keeps them breathing their best all year long.”

Wing will also help people with other respiratory conditions, such as COPD or cystic fibrosis.By plugging Wing into the headphone jack and launching the Wing app, a user can easily measure their lung function by blowing into the sensor. From there, the device will explain results according to a “stoplight” zone (green/yellow/red) system in order to detect declines in lung function early and help prevent asthma attacks.

Wing automatically stores and tracks lung function measurements over time and also allows users to track the two things that affect their lungs: medications and triggers (e.g. weather, pollen, exercise, etc.).

Beyond asthma, Wing will also help people with other respiratory conditions, such as COPD or cystic fibrosis, as well as anyone else who is interested in better understanding their lungs.

Wing’s companion app is currently an iPhone exclusive, with an Android app coming at a later date. Sparo Labs has submitted a 510(k) FDA application for Wing and is currently pending FDA clearance.
