IBM Watson and Twilio have been combined to create an app that answers health questions via SMS. The application uses IBM Bluemix, Node.js, Hapi.js, and Twilio to interact with the Watson Question and Answer API and send responses back to the user through Twilio's SMS service. The developer built this app as a fun project to test new technologies and to demonstrate how users can access health data via SMS. The application allows users to send in health-related questions and receive answers from the Watson API, which is hosted on Bluemix. The response is then sent back to the user through Twilio's SMS service.
