The founders of Sparo Labs came up with a new way for asthma sufferers to better manage asthma with a pocket-sized spirometer that connects with an app on your smartphone. The FDA approved device, Wing, measures lung function. The founders say the inexpensive technology helps you prevent asthma attacks and allows you to track your triggers. Sparo Labs is an Arch Grants recipient, receiving a $50,000 grant. The company continues to grow Wing in the tech startup incubator T-REX, located in downtown St. Louis.
