A native iOS and android app developed for Sanofi to support their epinephrine injector, Auvi-Q. By taking advantage of the smart phone’s own gyroscope and swipe functionality, we were able create an effective tool to help patients simulate real-world device usage—a key feature of the application. Auvi-Q Companion app was well received by client and patients alike while also being the recipient of multiple awards in the mobile health space.
