Walgreens has a long history of innovation in pharmacy services. Mobile apps are now an important part of their business strategy and omni-channel customer experience. Over 40% of Walgreens customers use their app in stores, and their first mobile app allowing prescription refills via photo scan was hugely popular, driving over 50% of online refills. Walgreens is now focused on using mobile apps to inspire customers through features like photo sharing and printing, and to transform their business through new platforms for health services and developing an API for other developers.
