The Ankylosing Spondylitis Journal is a simple application that enables patients to log their symptoms via SMS or phone call, using hashtags to record pain levels or flag symptoms for medical attention. The application was built using the Twilio API and PHP/MySQL technologies, with a seamless integration experience. Chris Bennett won the "Anything Goes" contest with his innovative application, which has gained traction and attracted users from around the world. The success of AS Journal has inspired Twilio to host an entire contest around Health and Fitness, encouraging developers to submit their own applications that use Twilio's services.
