User-friendly Banking with custom mobile apps by LeanCode
Our Banking success story
Modern Banking app development challenges
High costs of development and maintenance
Modern mobile banking apps need to cover all relevant from the users’ perspective features, starting with customer onboarding with KYC, KYB, biometrics, quick transfers, bank account statements, credit card issuing and provisioning, financial health checks, and many more. If the bank relies on the old native-only approach, the total costs of building and maintaining mobile banking apps are growing exponentially. At LeanCode, we develop native apps using cross-platform technologies such as Flutter, which, according to 56% of respondents from the Flutter CTO Report, helps to develop mobile applications more than 50% quicker.Separate teams for iOS, Android, and Web
The banking development teams, which need to keep the coherence between all channels in the omnichannel strategy, need to develop the same features separately for iOS, Android, and Web applications using separate teams, separate design systems, and separate test scenarios to avoid regression bugs. This is not only hard to manage but also extremely expensive and inefficient. This is why advanced mobile banking development teams like Credit Agricole or Millennium Bank use cross-platform technologies such as Flutter, which enable them to build the feature once and deploy it to iOS, Android, and the Web.Inconsistent mobile banking app performance
It is fundamental for banks to measure how effectively and reliably their mobile app operates to ensure the best user experience. However, some apps may be slow, crash, or fail to load properly, which frustrates users, stopping them from using the application's features when needed. LeanCode’s mobile banking application development embraces Flutter technology, which ensures seamless performance for Android and iOS users.Inconsistent UX and UI between mobile operating systems
Banking apps must be available on multiple platforms (iOS and Android) to reach a wide audience and deliver the same high user experience to each group of users. However, due to being forced to manage changes in UI and updates separately, delivering the same standards is often challenging. LeanCode helps build banking apps with all the advantages of cross-platform technologies, which solves these issues.Migrating a banking app from one technology to another
It happens that the technology on which a mobile banking application is based stops supporting its fast development due to its limitations. When banks cannot implement the features their customers expect, their position in the market can be weakened. Here, LeanCode comes to the rescue, with experience in mobile banking application development and app migration to Flutter using the established add-to-app for Flutter migration framework. Based on our previous banking projects, we know how to do it quickly and safely.The need for fast implementation of new features
The lack of features expected by users can lead to an increase in bad ratings of banking mobile applications in the app marketplaces, and this can result in abandoning the online banking services of a given bank by these customers. At LeanCode, we understand how important it is to add new features efficiently, and thanks to the experience of our mobile and backend development teams, we support banks in implementing innovations. Our client, Credit Agricole, during the three years of cooperation, advanced in customer reviews and popularity rankings run by Newsweek gradually to 10th, 7th, and in 2024 to 3rd location in Poland thanks to the fast implementation of new features and high app performance.Integration with the Bank's other channels and tools
An important factor in the success of mobile banking applications is their effective integration at the architectural level with other channels, contact centers, or even kiosk-type devices in branches and tools of the bank to enable a smooth transition between them and data flow. The ability to track the user's customer journey is also important. LeanCode is a tech partner that can support banks in addressing these challenges.Lack of tech experts to consult and implement changes
Banks are shifting their employment structures, reducing staff while increasing demand for IT skills. The rise of digital channels forces financial institutions to invest heavily in tools and provide adequate security and technical support. LeanCode offers IT Consulting to guide tech decisions and Staff Augmentation services, where our team strengthens internal banking teams and ensures the right skills are in place for digital success. We also offer training services based on our long-lasting training programs with university backgrounds, where we provide the training for the development teams to advance in modern development frameworks, such as Flutter or .NET.Examples of mobile banking features we implemented
