Mobile Banking App Development: [Trends, Guide, Cost 2025]

39% of people globally use banking apps as their main way to manage their money. 3.6 billion people use online banking worldwide in 2025. As digital payments have become more widespread, the field of banking mobile app development has also evolved to keep pace with the new trends. 

Today’s mobile banking apps offer a wide range of innovative features, from contactless payments to the integration of artificial intelligence. In this article, we examine the key trends in payment apps in 2025 and offer a solution for streamlining mobile banking app development.

Trends in mobile banking app development

Current market trends

Mobile banking is becoming increasingly popular, with nearly half of U.S. households now using it. This trend is particularly strong among younger generations and those with higher education levels. For example, almost three-quarters of 15- to 24-year-olds use mobile banking, and nearly 48% of college graduates do the same.

A full-fledged platform

Nowadays, a mobile banking app should not be just another finance application in a sea of available options. It should serve as a complete solution that meets all users’ financial needs and requirements.

This means offering a wide range of features such as account management, bill payments, fund transfers, investment options, budgeting tools, and even access to additional financial products and services.

Biometric authentication to use the app

To ensure the security of your financial information and bank balance, the future of mobile banking software development is focused on the increasing use of biometric authentication in mobile applications. 

Instead of logging into the banking app with PINs or passwords, users are expected to use their fingerprints via the smartphone touchpad. However, this also requires fingerprint-compatible devices.

Voice banking allows customers to interact with their mobile banking apps using voice commands. 

However, security concerns have arisen due to a previous incident involving a data breach related to voice banking technology. Read this article to learn why voice cloning technology can be dangerous.

Modern and intuitive UX/UI app design

According to McKinsey & Company, businesses that prioritize customer experience and design have 10-15% revenue growth over their competitors, which is why it’s important to offer a convenient and user-friendly app.

Nowadays, usability is one of the most important components of iOS or Android banking app development. 

Real-life example

Venmo, a mobile payments app, modernized the look of the app itself, which was a bit outdated and cluttered. The user interface was redesigned, the font was updated and a lot of white space was added to make it look fresh and clean.

Cardless ATM withdrawal

The concept of contactless interaction with ATMs has emerged as a trend, revolutionizing the traditional use of mobile banking.

Such integration with ATMs facilitates easy and contactless transactions, posing a real challenge to the traditional in-store banking model. The common approach to cardless ATM withdrawals is to use QR codes scanned on mobile devices via the banking app.

Customer personalization based on data

By analyzing a user’s transaction history, financial habits, and preferences, mobile banking apps can provide personalized product recommendations, budgeting insights, and investment options. This not only increases user satisfaction but also builds trust and loyalty.

Real-life example

A great example of personalization in mobile banking app development based on data is Spotify. By analyzing each user’s musical preferences, Spotify compiles a personalized playlist of previously undiscovered tracks that fit the listener’s favorite genres.  In this way, Spotify keeps its users coming back regularly, offering them an ideal platform for continuous music discovery.

Gamification

Gamification for mobile banking app development involves the use of game design techniques in a non-game context to encourage customers to use your app for a long time. For instance, many fintech apps offer rewards (such as money or points) for users who perform certain actions.

Please read our article on FinTech app development to explore how to develop a future-ready payment application.

Real-life example

Revolut, for example, offers a rewards system where users earn points for making transfers and payments. These points feed into a leaderboard that shows your progress compared to top users and your friends.

Points can be used to enter a weekly draw to win cash prizes ranging from €1 to €10,000, encouraging participation and activity in the app.

The higher the interactivity of your app, the better the user experience and the higher the customer retention. Features such as loyalty programs, cashback, and rewards will further engage users with your banking app.

Future outlook

The future of mobile banking seems promising, and further growth is expected. 72% of U.S. consumers prefer to manage their finances online or through a mobile app, signaling a strong shift toward digital banking solutions. This trend is likely to accelerate as more advanced features and enhanced security measures are implemented in mobile banking apps.

Key challenges of developing a mobile banking app

Regulatory compliance challenges

The financial sector is subject to a complex and constantly evolving regulatory landscape. Navigating through various national and international regulations, such as GDPR, PSD2, and KYC/AML requirements, requires careful consideration and expertise. In this article you can find more information about payment regulations. 

Security protocols and data protection

Both iOS and Android banking app development requires not only a deep understanding of financial regulations, but also robust security. Implementation of state-of-the-art encryption mechanisms to protect sensitive user data during transmission and storage. Robust encryption protocols, such as SSL/TLS, protect data from unauthorized access.

Cyber threat prevention includes continuous monitoring, penetration testing and the use of security best practices to reduce the risk of data breaches, hacking and other cyber attacks.

User experience and interface design

Designing an intuitive and user-friendly interface is crucial to increase user engagement and satisfaction. Users should be able to easily navigate the app, access key features and complete transactions with minimal effort. 

The app should also adapt to different platforms and offer a consistent experience so that users have the same range of functions and convenience regardless of the device used.

Integration of diverse financial services

The integration of a wide range of banking services, including transfers, bill payments, and account management, consolidates your app into a comprehensive, feature-rich platform. 

In addition, the seamless integration of third-party services such as payment gateways, investment platforms, and insurance providers offers users advanced functionality, increasing the value of your mobile banking application.
