Solutions Area: Design/UX, development, system integration, native app development
After several successful collaborations, St1 once again chose HiQ Oy to develop their new mobile application. The first launch took place in Sweden — with plans to roll out across the rest of the Nordics.
“We always evaluate our partnerships, and HiQ has been a reliable partner in both web and app development. So when it was time to build a new mobile app, HiQ was the natural choice,” says Tania Matvyeyeva, Project Manager at St1 Sweden.
The goal: A new digital service meeting future customer needs
St1’s customers had long used various payment solutions, from credit cards to private loyalty cards. As the market shifted, St1 saw the opportunity to go further — offering a modern, fully digital solution that simplifies the customer journey even more. Timing was critical as legacy payment solutions were being phased out.
Despite tight deadlines, HiQ’s team quickly turned the vision into reality. Through close collaboration with St1’s Nordic teams, a solution was created that combines cutting-edge technology with a simple and secure user experience.
“We wanted to give our customers something new and unique, even with a tight schedule. HiQ’s experienced team successfully drove the project forward and coordinated all parts in parallel,” explains Matvyeyeva.
Technical stability for multiple markets
A key part of the project was to build a stable and scalable platform that can easily adapt to all Nordic markets. By standardizing the technical framework, both further development and maintenance become smooth regardless of the country. The visual identity has been harmonized while allowing for local adaptations.
The app has been integrated with St1’s content management system, opening up new opportunities for targeted and personalized customer communication. Security has been a top priority — only information essential to delivering the service is collected, and customers control how their data is used.
The solution: A native app for a seamless and powerful user experience
St1’s new app has been developed using native technology, meaning it’s fully optimized for both Android and iOS using Kotlin and Swift — the programming languages recommended by Google and Apple. The result is a fast, responsive, and future-proof app that can fully leverage each phone’s built-in features.
Feature highlights include:
- Mobile refueling — quick and convenient directly in the app
- Simple payment — with card, Apple Pay, and soon Google Pay
- Visual map service — find stations and restaurants with full menus
- Intuitive use without mandatory registration — try the app before creating an account
- Personalized offers — with full customer control over data usage
- Digital receipt management — receipts stored in-app and easy to download for accounting
“Having an idea is one thing, making it reality is another. HiQ’s designers gathered the diverse needs of our Nordic teams and translated them into a functional solution. Developers, architects, and testers worked together to deliver a secure and stable application that performs in every situation,” says Matvyeyeva.
HiQ project team was involved throughout all project phases and successfully reached the challenging timelines and met the ambitious project expectations.

Next step: Expansion and continuous development across the Nordics
The launch in Sweden is just the beginning. The next phase is to roll out the new app across other Nordic countries and gradually introduce new features, such as barcode scanning to activate offers. The ambition is to continuously enhance the customer experience and provide users with relevant, personalized services.
HiQ and St1 demonstrate how close collaboration, modern technology, and high ambition create digital solutions that meet both today’s and tomorrow’s customer needs.
