After struggling for years with her own chronic health conditions, Corra’s founder, Elya, used her health struggles as inspiration for creating this app. The goal of Corra is to provide an app that allows each individual user to track and manage their own health goals. Elya wanted an app that not only supported her in her health journey, but also helped her identify what her individual triggers were. At Corra we firmly believe that each person is unique and what works for one person will not necessarily work for the next. For this reason, Corra’s proprietary A.I. software looks only at the data within your own account and derives correlations specifically from the logs you submit. Ultimately, we hope that this app, which was inspired by an ongoing battle with chronic illness, will be an app that helps other chronic illness users, spoonies, athletes, everyday parents, college students, the elderly, and anyone else who wants to receive individualized insights regarding their own health journey. At the end of the day, this app is a health app, and we all have health to manage!
