A GMI Case Study
Świat Książki launches loyalty app with GMI in 24 hours and 100,000+ downloads
Świat Książki, a major bookstore chain with over 130 locations across Poland, needed a mobile-first loyalty solution to digitize its plastic cards and create a unified channel for promotions, shopping, and product availability. The challenge involved integrating this new app with their long-running legacy store systems without compromising data integrity or slowing down development. They partnered with vendor GMI Software to develop this solution using React Native.
GMI Software implemented a React Native app featuring a digital loyalty card, a business-configurable home screen, and a robust integration layer for their legacy systems. The solution was delivered on time despite scope changes and achieved over 100,000 downloads, quickly reaching the top spot on the App Store. The vendor's work provided Świat Książki with a stable and scalable application that successfully connected their online and offline commerce ecosystem.
