Types of Mobile Banking Apps

As of today, mobile banking solutions comprise not only apps as they are but also some other versions. The main of them we describe below.


SMS banking is realized via text messages, which is a sign-up option. The users can then enquire about account balances, review abridged account statements, request current interest and foreign currency exchange rates, transfer limited amounts of money, and block debit or credit cards through specific SMS commands. Each bank has its own list of commands for the purpose.

Since the operations are initiated via SMS, a client does not necessarily need a smartphone or internet connection to use SMS banking.

Mobile Banking via USSD

USSD - Unstructured Supplementary Service Data, or quick codes as they are called, are used by mobile phones for communication. So, USSD banking also does not require an internet connection or a smartphone.

A user can request the menu of banking services with specific shortcut combinations and click on ‘send’. Then they can proceed with balance checking, mini statement requests, etc.


App-based banking is a service in the form of a mobile app designed by the bank and for the clients of this bank. Through a mobile user interface, customers can log into their profiles, navigate menus, locate bank branches and ATMs, or manage their finances on the go. They can also access customer service via chat or a phone call.

Sometimes banks offer diverse apps for different services. There are apps for checking account balances, paying bills, transferring funds, etc. A user can download one or several applications according to their needs and purposes.

However, it’s always more convenient to have a solution that serves as a one-stop shop for all user needs. So, let’s find out the core features of a banking app.

The Core Features of Banking Apps

To decide how to create a mobile banking app, you should make up your mind as to the features you want to implement in it. These features will prompt you on the tech stack to choose for your solution and consequently the way and methods of development.

Verification and authorization

Banks must use advanced security measures to comply with strict industry regulations. So, multi-factor authentication is a preferred feature for mobile banking applications. What is more, biometric authentication data (fingerprint or face ID) is also often used for account access. Secure authorization and verification functionality should become your first concern during mobile banking software development.

Transaction management

Account and transaction management should comprise the possibilities to check balance, view transaction history, deposit funds, and make payments and money transfers. Going a bit further, you can offer your users the option of scheduling regular payments, managing loans, and even paying bills.

Customer support

Customer support always adds up a sense of confidence. It is a crucial factor in everything finance-related. So, when developing a banking app consider real-time assistance with transactions, if there is a need for a user and in-app chat support. It’s reasonable also to have integration with other channels of communication.

More than that, to get a loyal audience, allow your users to customize their profiles and choose preferences. Thus, you can provide more personalized support based on your client’s individual needs.


Geolocation API integration will help your customers locate nearby terminals, ATMs, and bank branches. At the same time, it’s a vital feature to detect fraud or the reason for an alert if the mobile app operates from a suspicious location.


This relatively new technology allows contactless payments. Most modern customers have already got used to it. Today we can speak about NFC as a core feature for a banking app.

Internet payments

Lots of modern banks allow in-app payments through popular payment systems, like Stripe, PayPal, etc. You should offer these options to your users to be in trend.

Push notifications

It’s a critical feature for urgent messages and a useful one for regular notifications. The app can not be active all the time. Push notifications can inform of the account status changes. They can ask to authorize a scheduled transaction confirmation, to prevent fraud, or double payment, for instance.

The core functionality is undoubtedly important for a good user experience, convenience, app reliability, and security as well as for regulations compliance. However, to beat your competitors, you should supplement the robust core functionality with nice-to-have advanced features. They will enhance the service of your platform. Let’s turn our eyes to them.

Advanced Features

Unique value-added functionality can become a decisive factor for customers to try your product and stay with you. So, to retain your clients consider the implementation of the following features.

Chatbot and voice assistants

Such a functionality contributes to a more user-friendly interface and enhanced user experience. Nowadays, chatbots can handle up to 80% of routine tasks and customer queries in real time.

On the one hand, chatbots can cope with a great number of queries at a time, offering quick solutions and prompt responses to clients. Voice assistants are good helping hands to users who lack technological proficiency or possibly have certain disabilities. You can thus enlarge your user base. On the other hand, such chats and voice assistants save time and human effort for your personnel.

Expense trackers

Lots of people nowadays are trying to master financial awareness and get a comprehensive overview of financial behavior and spending habits. So, by allowing your clients to track and manage their expenses and save more, you'll attract those who are eager to master financial control and planning. Implement the possibility to categorize transactions, set spending limits, generate reports, and optimize spending, and your clients will appreciate this.

Cashback services

Cashbacks create loyalty and engagement. Implementing it you will turn your banking app into a rewarding monetary tool. In such a way you can encourage customers to use your mobile application consistently. It will also enhance the attractiveness and overall value of the mobile banking experience.

Personalized offers

Personalized offers to customers can become your win-win scenario. So, consider targeted discount generation, exclusive deals offering, cashback rewards, and other attractive options covering the interests of your app users. To gather the user data and understand the key spending patterns or preferences, you’ll need to implement ML and AI-powered algorithms.

Fraud alerts

Fraud alerts are something extremely important nowadays. Consider push notifications to enhance security. Make sure your clients are notified of potential fraud or suspective activity as quickly as possible.


This feature is useful in modern social settings when a person needs to divide expenses with friends, colleagues, or family. Splitting bills promotes an easy settlement of shared bills. It allows one to view the parties’ contributions, send reminders, and settle debts right in the app.

Integration with wearables

In the era of wearables, you can not miss the chance to allow your clients to access the necessary info effortlessly and instantaneously on their wearable devices. What is more, processing transactions right from the wearable and payments through NFC technology will surely become your competitive advantage.

Cash Withdrawal without a bank card

A good idea is to allow your banking software users to withdraw funds from ATMs through the confirmation in the app. It will prevent them from carrying an ATM card with them all the time.

Crypto Wallets

Crypto is a modern trend and the future that is already here. If your clients show interest in crypto assets, it’s wise to partner with at least major exchanges of Bitcoin, Ethereum, etc.

Why Building a Banking App May be Tough?

When questioning how to create a bank application, you should also think about what challenges can await you in this way. We are going to deal with this a bit and show you how to handle the difficulties.

Regulatory requirements, security, and data privacy of your customers should be your first and foremost concerns. Banking software has to comply with a large number of regulations. Serious financial penalties threaten those who fail to implement this. So, you should partner with software vendors who are security-minded and aware of the regulations due.

An intuitive and user-friendly interface with seamless onboarding should also be your constant focus. A banking app is used by various users, but not all of them are tech-savvy. It may become a challenge not to overload the interface with unnecessary elements and make it intuitive. However, UI/UX designers with relative expertise and experience will prompt you the right answers.

Anti-money laundering (AML) and know-your-customer (KYC) tools are a must. You have to implement them, otherwise you may face financial penalties. To exclude this choose the team of developers who know how to build a mobile banking app with a really reliable system of user authentication and authorization.

The ability to block payments should be instantaneous. Make sure the users can connect to their accounting system and block the bank card in no time in case of suspicious circumstances.

Build and verify a prototype

A complex mechanism of a banking app contains multiple features. It’s rather difficult to develop it from scratch. So, we advise you to make a prototype. Prototypes help to visualize the interface and functionality of the app-to-be. They help to establish effective communication between the development team and the stakeholders.

What’s more, by testing a prototype, the developers can test the idea with a target audience. They can validate tech feasibility, evaluate performance, and spot bottlenecks if there are any. The latter can be addressed at an early stage. A prototype is flexible and relatively cheap because it requires 10x fewer resources.

So, you can modify it and remove bugs right away without much expense. After approving a prototype you can proceed to developing a solution with a proven product-market fit.

Lay the groundwork for security

At this stage, you should make sure your banking app meets all the security standards, regulations, and data protection laws. The minimum regulatory requirements list contains GDPR, PSD2 , PCI DSS, and CCPA. However, each country has its regulations, so be sure to check all the legal nuances.

Design the UI/UX

Before you take up the UI\UX design of your banking application, business logic and functionality should be implemented in full. We advise to follow a holistic approach to UI/UX:

  • Choose clear menus.
  • Feature simplified navigation.
  • Make sure your clients can access all the essential services.
  • Keep in mind that web accessibility is legislatively regulated in some countries. Check the Web Content Accessibility Guidelines (WCAG) 2.2.
  • Develop the app

    As soon as your prototype is developed and tested, your UI/UX is well-defined, and the next stage comes. It's the stage of translating the conceptualized design and charted requirements into a mobile app. The development starts with building the server-side logic, business rules implementation, and integration of the APIs. They enable the app’s functionality.

    Then the developers deal with UI/UX to ensure a seamless user experience. Testing, security vulnerability improvements, and handling of all the usability issues also belong to this stage. Keep contact with the development team throughout the process to make sure the software will meet your expectations.

    Release and maintain

    When testing is completed and the majority of issues are handled, the application is launched. It's often uploaded into Google Play and AppStore. Here the next sage begins. On the one hand, you should keep in mind to pay for such technical aspects as server capacity, integration with payment gateways, support for some technologies, etc.

    On the other hand, the growing number of users will detect new issues and set new requirements forward. Be ready for that. Regular updates and innovations are what will always keep your application competitive. We know that the question of costs is the important question you are impatient to ask. Just keep reading and we’ll answer it below.

    How Much Does it Cost to Make a Mobile Banking App?

    The budget for a software solution is always subject to many aspects. They are the hierarchy of the workflows and their complexity, tech stack, 3rd party integrations. The more logical blocks an app contains, the more difficult the task is and the more specialists may be required. When developing for Android, you should keep in mind how to make a mobile banking app that operates on variable devices.

    The form of interaction with the developers and the chosen price format also matter. If you hire a dedicated development team for a rather simple solution, you can expect to start from around $100000. However, the more realistic budget for a competitive product is $500000. The sky is the limit for a complex banking app development.

    Another popular question is how long does it take to build a banking app. The first customer-ready MVP development can take between 6 and 12 months. Then follows about a year of full-fledged product development.

    Considering long-term investment for a banking app, keep in mind the figure of around a million US dollars. In the ever-developing world, ongoing yearly maintenance and updates should be regular to keep the market.
