My Viking app: Mobile Vikings launches new, user-friendly mobile app

Mobile Vikings, a telecom provider in the telecommunications sector, needed to replace an outdated, high-maintenance mobile app that limited usability and increased operational costs. ACA Group developed a cross-platform mobile app using React Native to streamline development and maintenance. This solution improves user experience, reduces development costs, and provides a scalable, future-proof mobile application for digital customer interaction.

Challenge

Mobile Vikings' existing mobile app was complex (written in two separate versions for iOS and Android) and costly to maintain. This hindered their ability to offer a user-friendly user experience for their data-heavy customer base.

Solution

Mobile Vikings partnered with ACA Group to develop a completely new app using React Native technology. This allowed for cross-platform development (iOS & Android) from a single codebase, significantly reducing development costs and simplifying maintenance.

Approach

A two-phased approach: quick fixes to the old app, followed by a complete rebuild with collaborative workshops to define requirements and leverage React Native for easy maintenance.

Result

An innovative, user-friendly mobile app with improved UI/UX, new features, and lower development/maintenance cost. The new app provides a better customer experience and empowers Mobile Vikings to more easily manage and update their mobile offering.

About Mobile Vikings

Mobile Vikings is a true pioneer in the telecom industry and offers subscriptions and prepaid SIM cards with unique formulas. Mobile Vikings’ customers enjoy many types of benefits, such as beneficial rates, free calls and text messages to other Vikings and Viking Deals for a lower telecom bill. The provider mainly focuses on users that require a lot of cellular data in their plans.

Mobile Vikings is part of DPG Media, a fusion of the former MEDIALAAN and the Persgroep Publishing. DPG Media owns other famous Belgian brands such as VTM, De Morgen and Qmusic.

Mobile Vikings offers a Viking app on iOS and Android that allows users to check their current usage, remaining data, current promotions and more. This app has become very outdated over the years and it was difficult to make simple adjustments, such as adding new products.

Additionally, the app was very complex and written in two different versions: one for iOS and one for Android. Therefore, changes in the app had to be made twice each time to keep the functionality of both versions the same. And that meant a twice as high development cost.

To address these concerns, Mobile Vikings chose to develop a completely new app. The new Viking app not only had to perfectly fit the look of Mobile Vikings as a pioneer in the telecom industry, they also dreamed of easy maintenance and a smooth user experience for all Vikings. And ACA Group helped to make this dream come true!

Mobile Vikings wanted to provide their customers with a pleasant working solution as quickly as possible. To solve the most urgent issues within the outdated app, we first analyzed the app and made some small and quick adjustments, such as support for new products, some visual improvements, and support for older devices.

After this first optimization phase, we started to work with Mobile Vikings to develop a completely new Viking app. During the next phase, we brainstormed and set up several workshops, in which we examined a new app together and mapped out improvements and requirements. The goal was to create an innovative, cost-effective, and user-friendly mobile application that would increase usability and streamline maintenance.

Innovative, future-proof and easy to maintain

ACA Group chose the React Native technology because it offers two vital solutions:

A drastic reduction in development costs,
and easy maintenance.

With React Native, we developed the new app in the weblanguage React. The final output of that development is a native app on both iOS and Android. Developing in just one language means we only need to make adjustments once, fix bugs once and only learn and maintain one codebase. This ensures a lower development cost, while Mobile Vikings is still able to offer a cross-platform app.

Because React is a web language, the web developers at Mobile Vikings can understand how the new Viking app is built. This makes it much easier for them to get to know the codebase and further develop the app. In turn, this makes small adjustments and maintenance much easier to perform and a greater amount of independence for Mobile Vikings.

A clear and attractive app interface is important for end users, which is why we’ve spent a lot of time on the User Interface (UI) and the User Experience (UX). Starting from the brainstorming phase all the way to during development, we gave and received a lot of input, worked closely with the internal UX and UI designers and examined all feedback critically and carefully. These combined efforts led to an app with a clearer and consistent flow between the various screens.

We also have made strong progress together on a functional level: end users can now view and activate Viking Deals via the app, we’ve added much more accessible FAQs and users can now easily find or choose their SIM in a new dedicated screen.

Goodbye, paper maze! We developed the Gebouwenpas, a single digital platform that brings together all real estate data

The Flemish government (public sector) faced fragmented real estate data spread across multiple agencies, making it difficult for citizens and stakeholders to access certificates, permits, and reports. ACA Group developed the Gebouwenpas, a scalable digital platform built on Liferay DXP with Spring Boot and Angular, centralising all building data into a single digital passport. Using an agile Scrum and Kanban approach, the solution delivers clear insights, secure access, and a future-proof system for both residential and non-residential properties.

Getting more out of Jira data: how I am ten gains better insights with JirAlytics

I am ten, a marketing agency working with diverse project types such as retainers and time-based assignments, struggled to turn fragmented Jira data into actionable management insights. ACA Group implemented JirAlytics, a data platform built on top of Jira that integrates with tools like Power BI to centralise reporting on billability, budgets, and timesheets. This resulted in a scalable, centralised reporting environment, enabling management to monitor performance and make faster, data-driven decisions across all projects.

OVAM accelerates digitalization with Low-Code: fast, efficient, and cost-saving

OVAM, the Public Waste Agency of Flanders, faced operational inefficiencies due to legacy IT systems and manual processes in case management and field operations. ACA Group implemented multiple applications using OutSystems low-code technology, including a web-based case management system, a mobile inspection app, and an asbestos cost calculation tool. This approach automated workflows, improved data accuracy, and reduced administrative effort, enabling faster processes, scalable digital solutions, and cost-efficient digital transformation across the organization.

Mijn Stadsapp: +20 municipalities in 1 mobile app

Smart Region Limburg (s-Lim), a collaboration of local governments, needed to reduce fragmentation in municipal communication and services across multiple municipalities. ACA Group developed Mijn Stadsapp, a cross-platform mobile application built with React Native that integrates data from various sources such as municipal websites, event platforms, and utility services. This solution centralizes local information and services in one app, improving citizen engagement and accessibility, and achieved rapid adoption with over 20,000 downloads in the first month.
