2,000+ Sign-Ups in 1 Week! AldiFest's Loyalty App Boosts Engagement
We built a user-friendly web app for Aldi Ireland, driving 2,000 sign-ups in just 1 week. We developed the app with Next.js to ensure a smooth and responsive experience for all users regardless of traffic volume.

How We Developed a Loyalty Rewards App for Aldi Ireland, a Leading Multinational Supermarket, to Boost Brand Loyalty
Aldi, a global retail giant, sought to deepen customer loyalty in Ireland with a fresh and innovative approach. They aimed to move beyond traditional loyalty programs to offer a more interactive and rewarding experience. To achieve this, we were tasked with designing a mobile responsive web app that encourages customers to upload their receipts and earn rewards for their purchases. This initiative, named AldiFest, was created to boost customer engagement and strengthen brand loyalty in the competitive retail market.
Through AldiFest, Aldi’s customers can participate in exciting promotional competitions by simply uploading their receipts from purchases over €25. The loyalty app offers attractive rewards, including Electric Picnic Tickets and Aldi Gift Cards, with weekly opportunities to win weekend camping tickets and 20 x €100 gift cards. By leveraging positive customer sentiment and modern technology, Aldi aimed to create a loyalty program that provides a cost-effective and engaging way to connect with customers, making Aldi a standout choice for shoppers in Ireland.
We used several technologies to ensure the loyalty rewards app was reliable, secure, and handled the large number of users smoothly.
Partnership Goal
The client sought a small, agile team with strong technical skills to develop a loyalty program app for their annual festival. They needed a team that understood the festival's needs, embraced new ideas, and used advanced technologies. Continued support was crucial for seamless app operation during the festival and beyond.
The goal was to create a loyalty program app by building an app that lets users join competitions by uploading receipts. Admins should have control to manage competitions and select winners. The app must be easy for users to upload receipts and for the system to pick winners, boosting festival engagement. Additionally, the focus was on enhancing retail loyalty program engagement through innovative loyalty app features and user-friendly functionalities.

Team Formation

Aldi, a German multinational retail chain, partnered with our client partner and us as a tech team to develop a customer loyalty program. Our team of six worked diligently to meet Aldi's needs, holding regular internal brainstorming sessions to analyze data and identify ways to improve user conversion rates.
For day-to-day collaboration, we used Slack for daily updates, Asana for project management, and Google Meet for daily stand-up meetings (DSM). This ensured clear communication and effective organization. Our team adopted an Agile approach, delivering features through weekly sprints, which kept us aligned with project goals and allowed for iterative improvements.
To ensure the app's security, we conducted a thorough pentest to identify and address potential vulnerabilities. When support issues or bugs arose, our team swiftly addressed them using a structured bug resolution approach.
We prioritized issues based on their impact, implemented fixes promptly, and tested thoroughly to ensure the app's reliability and performance remained high. This collaborative and proactive approach ensured the successful delivery and continuous improvement of the Aldi loyalty rewards app.

Our Partnership
We were excited to collaborate with Aldi Ireland, a global retail giant with over 6,500 stores, to develop a receipt and rewards app for their annual festival. Throughout the project, we focused on understanding the festival's unique audience and environment while adhering to strict timelines.
After the festival season, we optimized costs for Aldi by reducing server capacity. Furthermore, we implemented a feature that automatically shortlisted users based on the number of receipts they uploaded, where each receipt counted as one entry into the competition. This streamlined the competition process and encouraged active participation among users.
Without this feature, the competition process would have been more cumbersome and less transparent. For example, if users were manually shortlisted, it could lead to errors, delays, and potential unfairness. Users uploading multiple receipts might not have seen their efforts rewarded proportionally, leading to frustration and decreased participation. Our automated system ensured fairness and efficiency, enhancing user satisfaction and engagement.
