Problem
need fora loyalty program
North Fish needed an amazing loyalty program. They wanted to show appreciation to their longtime customers and open a new sales channel via a dedicated application.
The new app was also to present the individual menu options in a tasty and appealing manner, and other equally important pieces of information such as the nearest restaurant finder.
Their old app was a long way from North Fish’s new requirements. It had presented only the current promotions and basic brand info, without any loyalty features or m-commerce functionalities.
Solution
a loyalty programin a native app
We designed and developed a comprehensive loyalty program in a native application for both Android and iOS. The app enables users to collect and redeem points for the brand’s products, physical or virtual rewards.
It means that customers earn points for eating at restaurants and the points could – in turn – be used either to collect rewards or to be used during visits to the restaurants. We called it “the mechanism of infinity.”
App Redesign
modern lookapp redesign
Several years after releasing the previous version, we completely overhauled the app's design, transitioning it from an outdated interface to a modern and trend-focused experience.
The redesign prioritised visual appeal and usability, ensuring the app aligns with current standards. This transformation significantly changed the look & feel, attracting customers' attention, encouraging them to check out the offers and visit the restaurants.
Development
new featuresand improvements
In addition to implementing the loyalty program, we enhanced the app's functionality and overall user experience. Key updates included optimising processes and introducing new features, such as exciting challenges for customers.
All the improvements significantly boosted user engagement and created a more dynamic and rewarding app experience, while ensuring greater customer loyalty.
Outcome
results much higherthan expected
In just 4 months after the first release, almost 63,000 registrations were made, with over 90,000 app users. From the very beginning, there were over 21,000 active accounts a day! From September to early January, almost 22 million points were awarded in the loyalty program for products purchased in restaurants – points are directly spent in PLN by customers who identify themselves at the checkout with a unique code in the application, where PLN 1 is 10 points in the program. At the same time, almost 5.5 million points were exchanged for prizes (own products and non-cash prizes).
Our Contribution
what we have donefor this project
research and understanding
We devised the way to implement the complex loyalty program, along with its “mechanism of infinity”, which allows users to collect points for buying North Fish food items in order to buy further North Fish offerings.
user experience in hand with design
We designed the app to be intuitive, user-friendly and above all else to have an exquisitely fresh look. As well a way to link the app with the external cash register system used in the restaurants. Finally, we devised a way to implement the rules of the loyalty program in the app design.
mobile app, backend development
A native app for both Android and iOS devices was figured that would bridge the way for the app to communicate between the points of sale and our environment, while at the same time implementing our “mechanism of infinity”.
