Mobile Banking App Market

If you’re reading this, you must be quite familiar with the market, but let’s quickly recap the state of affairs to make sure we’re on the same page about banking mobile app development.

Banking Apps Today

According to an MX study, the deadly virus has definitely played its part in the 50% surge of mobile engagement with banks.

“Americans are turning to mobile banking as a way to take control of their finances and plan for their economic future.”

Ryan Caldwell, founder and CEO of MX

This growing demand for remote bank services may indicate that we’ll see more apps released by smaller banks, which have been slow on adopting mobility solutions. According to the FDIC, only 9.5 percent of Americans favored mobile banking in 2015; and in 2021 this number flipped to 43.5 percent.

Back in 2018, more than half of community banks didn’t have a mobile presence. Note how customer value a highly rated mobile app today, according to Forbes Advisor Feb 2023 Survey:

Research paints a bright picture, predicting almost a $2-billion milestone for this market by 2026, but the result remains to be seen. Here are some more reassuring stats:

  • more than 75% of Americans used a mobile to check their account balances in 2019
  • 71% of consumers used a mobile wallet to make a payment in 2021.
  • 89% of Americans use mobile apps by banks for account management
  • 217m digital banking users (with digital wallets) in the U.S. by 2025
  • In 2022, JP Morgan led with mobile banking customers (50m) with Bank of America at the second place with 35.5m of active mobile customers.

Let’s explore the latest happenings in the mobile banking sector to understand growth challenges and identify some low-hanging fruit.

Mobile Banking Trends

Neobanks vs. challenger banks vs. traditional banks vs. tech giants

One of the biggest trends we notice lately is neobanks (startups without a banking license) are turning into challenger banks (those with a license). And traditional bank branches buy up or partner with both.

A case in point: Varo — a digital-only mobile financial service — will be moving its 2 million accounts from The Bancorp Bank to Varo Bank, after receiving approvals from the FDIC and Federal Reserve. Another example: Google is partnering with BBVA, Citi, and a handful of other financial institutions to bring accounts and other financial services into Google Pay in 2021.

Voice control

As voice is becoming a ubiquitous tool for controlling mobile devices, banks are integrating their apps with Siri, Alexa, and Google Assistant. Alternatively, some choose to build their own voice assistants from scratch.

mobile banking app using in-app assistant erica

A case in point: US Bank has just launched an in-app voice assistant to help its customers quickly navigate the app amid pandemic using natural voice commands.


Chatbots are very similar to voice assistants, except they rarely talk, offer question templates, and overall resemble dumbed-down versions of AI-powered assistants. Still, millennials, who grew up on messaging, may prefer this navigation to find a specific service, transaction, or helpful tip.

A case in point: NOMI, Royal Bank of Canada’s chatbot serves 1.1 million customers per month. It has answered 1.9 million questions from customers since the bank added the new feature in spring 2020.

Artificial intelligence

We can’t just miss AI and machine learning since they power pretty much the rest of the fintech revolution. But you get it, it’s everywhere.

Types of Mobile Banking Apps

Understanding the different types of mobile banking apps is essential for tailoring your mobile banking project development strategy to meet various user needs. Here’s a breakdown of the main types:

Retail Banking Apps

Retail banking apps are designed for individual consumers, providing everyday banking services right at their fingertips. Features typically include:

  • Account Management: Access account balances, transaction history, and manage multiple accounts.
  • Fund Transfers: Transfer money between accounts or send money to other users.
  • Bill Payments: Pay bills effortlessly through the app.
  • Personal Financial Management: Budgeting tools and spending insights.

Whether you’re focusing on retail banking, corporate finance, or innovative neobanking solutions, each type offers unique opportunities to enhance user engagement and satisfaction.

Wrapping Up on Trends

Why do we think our choice is characteristic of the current situation in the US mobile banking market? Well, the deal is neobanks and challenger banks take about 3% of the market share, and the big boys aren’t going anywhere. Instead, there are many partnerships, mergers, and acquisitions between mobile fintech startups and traditional banks.

Conventional banks are trying startup models to come up with new mobile products, and fintech companies, like Revolut, keep innovating from the other side. Both meet somewhere in the middle. I believe all fintech startups working on a mobile banking product seriously consider a buy-out or acquisition as a successful exit strategy from the get-go. And incumbent banks get a nice shot of innovation every time they acquire the results of mobile banking application development from startups.

Now, with that out of the way, we’ll focus more on how to code a banking app.

Read our guide on how to build a fintech company.

Why You Should Make a Banking App

Long story short, banks cut operating expenses, sell more products per customer, and attract and retain more users when they’re able to provide outstanding mobile customer service.

Startups sell to traditional banks or eventually become banks and make money, generating on average 10-15% of the invested amount per year. That and customers’ cravings for a 24/7 mobile user experience make banking app development a no-brainer.

why develop mobile banking apps

That’s it, and you already know it better if you’re in the business. Oh, and smaller banks and credit unions do play the catch-up game to retain their customers. All are good reasons to start a banking app.

Benefits of Mobile Banking Application Development

Round two: Why should we create mobile banking apps? The advantages are numerous and multifaceted, particularly for financial institutions looking to stay ahead in the digital age.

  • Enhanced User Experience: Mobile banking apps offer unparalleled convenience. Customers can manage their finances anytime, anywhere, reducing the need for physical branch visits.
  • Increased Customer Engagement: Interactive features like real-time notifications, personalized financial advice, and loyalty programs keep users engaged and loyal.
  • Cost Efficiency: Automating routine transactions and inquiries through banking apps significantly cuts down operational costs for banks.
  • Data-Driven Insights: Access to user data helps banks understand customer behavior and preferences better, allowing for tailored services and products.
  • Competitive Advantage: Offering a robust mobile banking app sets you apart from competitors who lag in digital innovation.

Creating a mobile banking app not only fosters customer satisfaction but also drives growth and profitability for financial institutions.

Must-Have features

If you’re just starting to custom develop your app, it better live up to customers’ expectations. And they’ve had quite a while to grow them. Here are some basic features an average Joe expects from a modern banking app (minus the trivial stuff like customer support and showing the nearest ATM and branch locations).

Balance and transactions

At-a-glance balance and transaction history have become the cornerstones of a mobile app produced by banks. That’s usually the first thing end users see after onboarding an app: show them what they own and let them quickly find and identify transactions.


Mobile payments are why everybody loves banking from their sofas. Integrate with as many payment services providers as possible to allow your customers to pay for their everyday expenses, transfer money to friends and family, and pay off loans and mortgages. Ideally, they should be able to pay for anything at all. In that sense, banking apps act as pure payment systems.

Check deposit

Another nifty feature that saves your customer a trip to the bank when they need to deposit a check. Instead, they take a photo of the check from both sides, endorse it, and upload it via the app.

Push notifications

These are push notifications nobody likes to miss. Besides offering account status updates, notifications may ask for authorizing a scheduled transaction, which users can greenlight with a single tap. That’s a perfect tool to get someone sign up for automatic pre-planned payments. There’s no developing smartphone banking apps without push notifications these days.

Manage cards

Customers should be able to block their credit and debit cards, assign them to a different account, set limits, change the PIN code, and do many other things that their banks support.

Bio authentication

Robust security is everything, especially when it comes to personal finance. By adding support for fingerprint (e.g., Touch ID), FaceID sign-in, or other biometric authentication, you make your customers feel at ease and protected at the same time. And everybody likes to tap or glance at a phone to be able to sign in.

Expense tracking

Ok, I’m on the fence with this one. On the one hand, all major smartphone banking apps show graphs or pie charts with the user’s expenses grouped by categories. On the other hand, if you’re just starting, that’s probably not something your customers can’t live without.

banking app Chase Mobile budget feature

So much for the core features.

Advanced Features

Now, suppose you want to create a banking application that will rise above the crowd. In that case, you should envision some unique value-adding features. And if you want to join the top ranks, consider adding the following functionality at minimum.

When I fire up my banking app, I get what I need right in front of me: the currency exchange rates, payment templates, balance, and pending transactions. How did I get this? My bank graciously allowed me to customize my screen this way by letting me toggle off and rearrange panes they display in the app. Of course, I’d prefer the app to do that automatically based on how I use the app, but we get what we get, right?

Cardless ATM access

Being able to withdraw cash when you forget the card in your car is a big deal. Some apps will have QR codes or some other form of interaction with ATMs to let you in, even when you don’t have a card.

mobile banking app allow you to access ATM without a credit card

Access other bank products

Easy access to the rest of bank products within a mobile app ensures you will get maximum value per customer. At the same time, customers can take out a loan right where they are, in the moment, without having to visit a physical office.

Chatbot or voice assistant

The cherry on top, that’s what a robust chatbot or voice assistant can become to your app. Bank of America reported that only 1% of their mobile customers (of over 27 million) turn off Erica, their AI-enabled chat & voice assistant — a user-friendly conversational interface.

Custom alerts

In addition to regular notifications informing users about their recent transactions and balance status, you can enhance the app with alerts that trigger based on different criteria. Such alerts will pop up upon reaching daily or monthly expense limits for particular types of transactions, etc.

Apple Watch Companion App

An Apple Watch app can be a nice addition allowing customers to quickly view their balance or make secure payments in stores. Remember, an intuitive interface here means that you don’t need to pack a whole lot of features on a tiny screen; just offer your customers glanceable experiences.


Stock and bond investment can play its part in a banking application. Even though major players prefer to develop a separate mobile solution for investing purposes, there’s nothing stopping you from providing the basic buy and sell options right inside the main banking application.

Crypto wallets

Crypto is a shady topic when there’s a bear market, but during the next bull run everybody is going to be talking about it again. If your customers are interested in crypto, the least you could do is partner with companies that offer major coins, e.g., Bitcoin and Ethereum, for trading.

Ok, that’s it for the key features. Now, let’s move on to discuss the nuances of mobile application development for banking.

5 Steps to Building a Mobile Banking App

Let’s quickly review all the steps before going into the details. Here’s the list of major steps you go through during the development of mobile banking solutions:

  • Step #1: creating a quick prototype and checking its usefulness with real users
  • Step #2: setting up the security framework (inside the application and outside: operations around app creation)
  • Step #3: iterative coding
  • Step #4: meaningful integrations
  • Step #5: beta launch and more testing
  • Step #6: maintenance

And now let’s talk about the essence of digital banking app development.

Step 1: Build and verify a prototype

You’re probably thinking, “I need to figure out the app’s architecture first: Do I want it built as microservices or SOA? What programming language should I choose?”

While those are important decisions, you should start by focusing on your customers. What business needs are you trying to cover with an app? How and when are they likely to use the solution? These and many other questions will help you answer your main question, “How to make a banking app?”

To answer these questions, you build a prototype and test it with your target audience to see if they are using it the way you envision. The prototype is confined to working on the app design, and no coding is required.

Fortunately, a prototype requires 10x fewer resources to build and verify than developing a full-fledged mobile app. And developing a smartphone banking app is no easy feat, requiring lots of resources (more on that later).

it's 10x cheaper to fix a design flaw while prototyping than during development

A business analyst will then help you use customer feedback to iterate on the prototype until everybody is happy with the customer experience.

This approach implies that you’ll be ready to develop a solution with a proven product-market fit without wasting your resources. Fortunately, changes at the UI/UX design step don’t cost a fortune.

Step 2: Lay the groundwork for security

Whether you’re a traditional bank or a startup looking to revive mobile banking, customers expect top-notch security. After all, they are trusting the app with their money. So, you have to develop a secure mobile banking app, ensuring data safety.

Positive Technologies have recently published their findings based on the research of vulnerabilities and threats in mobile bank solutions for several large banks. They’ve discovered somewhat not very comforting security measures in place:

  • In 13 out of 14 applications, attackers can access cardholder data from the client-side.
  • 76% of vulnerabilities can be exploited without physical access to the device.

security while developing a mobile banking app

Not only do you need to protect your app and the server-side, but you should also inform customers (and your employees) about cybersecurity best practices. On the app’s side, you need to consider:

  • source code obfuscation so that attackers can’t decompile an app and glean data for hacking
  • removing names of classes and methods from source code
  • adding protection against code injection and repackaging
  • use SSL and 256-bit encryption
  • comply with the rest of PCI DSS requirements and other fin regulations
  • enhanced security audits are also in order

Some of the top-of-the-line safeguard practices that make a mobile banking app more secure include:

  • verification of transactions with a short code sent via a push notification
  • multi-factor authentication (or at least two factor authentication via phone)
  • regular password updates
  • limited session time (log out users after a set interval of inactivity)

You should also remember the user comfort and include features that simultaneously protect and simplify app usage when you create a bank app:

  • allows short pin codes for easy access
  • support bio authorization: fingerprints and FaceID
  • require end users to change pins regularly

Step 3: Execute a.k.a code the banking app

Programming the app will be the most time-consuming step. That’s when banking app developers take the prototype and turn it into a live app. And even though your mobile banking development process will largely depend on the specifics of the product, some general recommendations can help you transition smoothly. [#protip: partner with an experienced product development company]

Native is a must

We recommend using native programming languages. The typical technology stack includes Swift for iOS and iPad OS and Kotlin or Java for Android. Those are officially supported by Apple and Google and provide you with full control over every aspect of the app.

If you’re playing a catch-up game, though, and need to push something quickly to stop customer drain, React Native or Flutter is a viable cross-platform option for simultaneous iOS and Android banking app development. You get an iOS and Android version on a smaller budget and faster with this tech stack.

If you only want to build Android banking apps (let’s say all your customers are on Android phones), then your choice is Kotlin.

Agile is more than a buzzword

Setting up your banking app development process the Agile way gives you these benefits:

  • full transparency of the progress
  • ability to pivot if something changes (internal processes, market, etc.)
  • faster time to market

DevOps matters

Another buzzword you may think, but wait. If you spend time at the beginning of the project to set up a DevOps environment and procedures properly, what you get later is regular updates to your apps.

Continuous integration and delivery tools ensure your developers can focus on adding features and fixing issues — app updates ship as if by themselves.

Continuous integration and delivery tools ensure your developers can focus on adding features and fixing issues — app updates ship as if by themselves. With DevOps, coders spend zero time fiddling around preparing another version for testing; instead, they create a banking application in Android and iOS full steam ahead.

Pluggable code is not always an option

We recommend using the least amount of open-source or commercial code in your app. Only if you can thoroughly test code for vulnerabilities and modify it yourself should you consider using third-party solutions. The thing is these products keep developing, and their updates can break your app. So even if you choose to do so, pick trustworthy suppliers, like Plaid, Ficinity, or Quovo.

QA is your everything

Testing starts as soon as developers have shipped a feature or two.  That goes back to Agile, which involves testing the app after each iteration (usually 2 weeks). Needless to say, you should run regression and unit tests before releasing your mobile banking solution to a small, controlled group of loyal users.

As with any sizeable project, you can’t do without automated tests during mobile banking software development. So, make sure your software development company sets these up from the get-go; long before you plan to launch the product.

Step 4: Enhance the app by integrations

We’ve already mentioned Plaid, an API that allows fintech apps to connect with user bank accounts (with their permission), but there are other third-party services you could use in your app.

bank of america and Zelle integration

A good example is Zelle. This service has found its way into many banking apps for simplifying cross-bank money transfers. With Zelle, users can send payments to friends and family regardless of the bank they’re using.

Another service you may find useful is Docusign. It can help you easily create mobile-friendly agreements that users can sign right on their mobiles. Let us know about your goals with the banking solution you envision, and we’ll recommend appropriate vendors.

Step 5: Release and maintain

The most pleasant and rewarding stage of the entire adventure, right? Only if you have the right development partner who will help you get through a thorny maze of the review process in the App Store and Google Play. And remember to stress-test your servers to ensure customers won’t bring it down on the release day.

And that’s how you create a mobile banking app with the potential to generate real traction with users.

Challenges of Banking Apps Development

Developing a mobile banking application comes with its own set of challenges. Understanding these hurdles is crucial for a successful launch.

  1. Security Concerns: Ensuring data protection and secure transactions is paramount. Implementing multi-factor authentication, encryption, and regular security audits is essential.
  2. Regulatory Compliance: Financial apps must adhere to stringent regulatory standards, such as GDPR, PSD2, and AML/KYC requirements, adding complexity to development.
  3. Integration Issues: Seamlessly integrating with legacy systems, third-party APIs, and other financial services can be challenging.
  4. User Trust: Building a trustworthy app requires a focus on user experience, reliability, and transparency. Any security breach or downtime can severely impact user confidence.
  5. Scalability: As the user base grows, the app must be able to handle increased load without compromising performance.

To successfully create a bank app, developers must navigate these challenges with expertise and careful planning.

What Tech Stack is Needed for Mobile Banking Development

When you set out to develop an online banking application, choosing the right tech stack is critical for ensuring optimal performance, security, and user experience. Here are key components to consider for banking and finance app development:

Frontend Development

  • Languages: Swift (iOS), Kotlin (Android), React Native for cross-platform.
  • Frameworks: Flutter, AngularJS, or Vue.js for responsive and interactive UI.

Backend Development

  • Languages: Java, Python, Ruby, or Node.js for server-side logic.
  • Frameworks: Spring Boot, Django, or Express.js to streamline development.


  • Relational Databases: PostgreSQL, MySQL for structured data storage.
  • NoSQL Databases: MongoDB for flexibility and scalability.


  • Encryption: SSL/TLS for data in transit, AES for data at rest.
  • Authentication: OAuth 2.0, JWT for secure user authentication.

APIs and Integrations

  • Payment Gateways: Stripe, custom modules for processing transactions.
  • Financial Data APIs: Plaid, Yodlee for accessing external financial data.

By leveraging the right technology stack, you can ensure that your mobile banking app is secure, scalable, and offers a seamless user experience.

Cost of Developing a Mobile Banking Application

Before you go and raise money to build your own banking app, let’s discuss how much you’ll need approximately. How much does it cost to create a banking app?

A couple of millions with an in-house development team, and between $300,000–$500,000 with a contractor team. That’s an approximate price range for building a banking app from scratch. And if you are a fintech startup looking to address a niche customer need with a mobile app, the cost of developing your app should squeeze within the $180,000–$260,000 range to get the first working MVP out.

Annual maintenance will end up at around $130,000 for the two variants, respectively. But the long-term investment strategy for such an app should absolutely base north of $1 million. How long it takes to develop your app will depend on the team involved, features of the app, but anything between four to six months for a proof of concept is what we’ve seen depending on the specific features and complexity of the app. A dedicated team can get a releasable MVP ready within 9-14 months.

To give you one example, a new mobile banking startup called Step had raised $3.8 million in a seed round before they got $22.5 million from Stripe and started building a full version of their teen-oriented mobile banking app.
