Aldi, a global retail giant, aimed to build strong customer loyalty in Ireland. They wanted to offer a unique and engaging experience that differed from traditional loyalty programs. Our task was to design a mobile-friendly web app that incentivizes customers through receipt uploads and rewards them for their purchases.

Have further questions?

  • How can I ensure my festival app can handle large user spikes?

    Scalability is crucial for festival apps. We built AldiFest with Next.js, a framework known for its performance and ability to handle traffic surges. This ensures a smooth experience even with a massive influx of users. Additionally, a robust back-end built with Node.js provides the stability needed for real-time data processing.

  • What are the benefits of using a receipt upload feature in a festival app?

    Receipt uploads incentivize user engagement and provide valuable customer data. AldiFest rewarded receipt uploads, encouraging participation and gathering purchasing habits. This data can be used for targeted marketing campaigns and improved product offerings.

  • How can I create a user-friendly app for a diverse festival audience?

    A simple and intuitive design is key. AldiFest prioritized a one-tap receipt upload process, making participation effortless. Using a UI framework like Ant Design streamlines this process and ensures a visually appealing interface for all users, regardless of age or technical expertise.

  • What are the advantages of using a Content Management System (CMS) in a festival app?

    A CMS allows for real-time updates within the app, keeping users engaged. In AldiFest, Aldi used the CMS to announce upcoming contests and showcase winners, creating a dynamic and interactive experience that boosted user retention.
