Earlier this week, Propeller Health released an application programming interface to give local asthma conditions to anyone within the U.S. who is interested in using that data.

The Air by Propeller API is a free service that uses a machine-learning model based on millions of days of anonymous asthma symptom data and environmental data. The model uses that information to predict potential effects on people’s breathing.

In Wisconsin last week, the company held a one-day hackathon at Camp Wandawega where teams built a series of free tools using the API.

“Each year, we return to Camp Wandawega to recommit ourselves to creating a company no one else can build,” CEO David Van Sickle said in prepared remarks. “Our culture brings together people who are passionate about health, passionate about technology, and passionate about inventing the future, and puts us to work to solve problems for people with respiratory disease and for those who care for them.”

Some of the tools created at the hackathon include integration with Alexa and Google Home and an embeddable Air Widget for websites.

“We’re excited to release the first version of Air by Propeller, a set of services designed to enable a larger audience to help people with asthma,” CTO Greg Tracy added. “With the new infrastructure and services, people will be able to make use of Propeller’s analytics, which draw on the largest database of respiratory medication use, environmental exposures and conditions. We look forward to seeing how others build on this to change the experience of respiratory disease.”

Propeller said it plans to roll out additional tools from Air in the coming months.
