Creating a new app with an existing code base

Fresh and delicious meals from Taco Bell have always been a favourite. Restel, the operator of Taco Bell restaurants in Finland, sought to create a digital sales channel for Finnish taco fans.

Our solution was to develop a visually appealing, Flutter-based mobile application that not only offered a seamless ordering experience but also included a loyalty program and home delivery options. One unique aspect was that the app had to integrate seamlessly with existing backend services and utilise the same code base as the Burger King Finland app. Up to 95 % of the code for the Taco Bell app already existed.

User tests were a crucial part of creating the Taco Bell mobile app

Taco Bell offers a wide range of possibilities for customers to customise their orders just the way they like them. As great as this is, it was also a usability challenge; how to provide an interface that minimises user steps and maximises the colourful and rich menu options so that users can keep track of the order as they should. Testing with real Taco lovers was a mandatory part of the project. As we combined user feedback with the technical possibilities that Flutter provides, we were able to create a streamlined ordering experience with visually rich details and animations. Something that complements the joyful and colourful Taco Bell brand.

Using the same codebase as previous apps, such as the Burger King Finland app, presented its own set of challenges. It was crucial to implement new features specific to Taco Bell without disrupting the functionality of other apps. Successfully maintaining and expanding Restel’s app family was a significant achievement. This multi-brand app family enables Restel to efficiently utilise it for a variety of restaurant brands in Finland, cost-effectively.

It is the good old teamwork that makes this possible!

The successful development of the new Taco Bell app was a result of seamless collaboration between our designers, developers, and Restel’s team. This teamwork ensured that the app not only visually highlighted Taco Bell’s delicious offerings but also enabled users to find and customise their favourites with minimal clicks.

Despite the complexity of the project, leveraging the existing codebase from Restel’s app family allowed us to deliver fast and cost-effective solutions, showcasing the professionalism and experience of our team.
