What are the Types of Mobile Banking Apps?

  • Retail Banking Apps: Retail banking apps are mobile applications that banks and other financial institutions offer to their retail customers to deliver various financial services and functionalities. These applications are made to give users easy access to various banking services, including account management, bill payments, etc. Wells Fargo, U.S. Bank, and JP Morgan Chase are some examples of retail banking apps.
  • Investment Apps: Investment apps are mobile applications that let you invest your money anytime, anywhere in various products, including stocks, bonds, mutual funds, ETFs, commodities, etc. Stash, Wealthbase, and Robinhood are some examples of investment apps.
  • Neobank Apps: Neobanks are completely online-based, digital banking services. Simply put, they are not present physically. Transactions in traditional banks could take a lot of the customer’s time and effort, but with neo-banks, it’s just a few clicks. Frio, FiMoney, and instantpay are a few examples of neobank apps.
  • P2P Payment Apps: P2P Payment Apps have simplified money transfers by requiring only a name, email, or phone number to send or receive funds almost instantly.  Through these apps, each account is connected to the other user’s digital wallet. As soon as the transaction takes place, the application’s account balance logs it and immediately withdraws money from one user’s bank account or app wallet and sends it to other users. Squarquash, Popmoney, and Venmo are a few examples of P2P Payment Apps.

What is a multifunctional mobile banking app?

Some banking apps combine various financial services onto a single platform, including banking, investing, and insurance. These applications strive to give users a thorough financial management experience. Apps like Ally and Discover Mobile are perfect examples of multifunctional apps.

What are the Challenges of Mobile Banking App Development?

In 2011, the Royal Bank of Scotland made history by launching the world’s first-ever feature-rich mobile banking app. Today, more than 90% of the population utilizes digital or mobile banking. With everything being online, the security risks increase, too. Data security is one of the most crucial factors in developing a mobile banking app. Let’s have a look at the challenges that can arise during mobile banking app development:

User Data Protection

The number of data breaches has increased over the last few years. It is essential to encrypt data with exemplary security standards to avoid any hassle in the future. As mobile banking apps solely function on user data, developers must utilize the latest security tools and techniques like two-factor or multi-factor authentication. They must ensure regulatory compliance to provide a safe environment for users.

Regulatory Compliance:

Your application is going to serve users globally. However, achieving regulatory compliance takes a lot of work. Below are some necessary compliances to consider while developing your mobile banking app:

  1. The Fair Credit Reporting Act ( FCRA) protects customer privacy and information accuracy. Reports created by service providers often include characters and assets. This act restricts the disclosure of any such sensitive information.
  2. General Data Protection Regulation (GDPR) is mandatory for all apps that collect user’s sensitive data. This act aims to improve privacy protection and unify data privacy laws.
  3. The Gramm Leach Bliley Act ( GLBA) regulates or controls customers’ private information collection or disclosure. The service provider must disclose the product’s information-sharing policies and practices.
  4. Money Transmitter License (MTL) is a must for all organizations to comply with the act if they are involved in any monetary operations. The mobile banking app will bridge users and the financial institution.
  5. Money Service Business ( MSB): According to the compliance protocols, mobile banking application developers must register the product through the BSA e-filing system. Adhering to this compliance reduces AML risks, and your app adheres to BSA reporting regulations.

Adding the Right Features

Research the pain points and the demands of users. This will help developers to create a ready-to-market app. Even if you have a solid online presence, your app must satisfy consumers. If your app doesn’t perform well, it can also hamper your reputation. A robust, feature-rich application helps you stand ahead of your competitors.

7 Steps of Mobile Banking App Development Process

Mobile banking applications are very popular as they ease customers’ lives. Here is the step-by-step process of building your mobile banking application.


This is one of the most crucial steps to be taken if you are considering getting a mobile application developed. It’s essential to have a thorough competitive analysis of the market and your competitors. Proper research helps you build the right strategy. You need to list all the essential points, like who the users are, their pain points, and how to address each. The output should be a detailed mobile banking app development plan with all estimates. A thorough analysis gives you all the information from user persona to value proposition.


Mobile banking apps are complex projects, so it is essential to understand the specifications and build prototypes. After the prototype approval, further actions can be taken. Make sure you know the requirements and expectations. Building a prototype is a comprehensive process that helps understand the scope of future work and design a product that meets users’ needs.


Data Security is the primary element that needs to be taken care of while developing a robust mobile banking app. Some organizations will only hire you to create applications that offer strong security. Security is non-negotiable in the banking domain. One must follow robust authorization protocols, security encryptions, two-factor authentication, and other added security while developing a mobile banking application.


In this step, the design team or the designer should roll up their sleeves and start working. If you are building an application to facilitate your customers, delivering a great user experience is vital. Navigation should be smooth, and the app should be user friendly. If you are dealing with any operation that involves money handling, it must not have any chances of error that can trigger users. When users deal with a big chunk of money, they are nervous. That’s why developing a simple, intuitive, user-friendly interface is essential.


And here comes the final development phase. All the research, design, prototype, and testing come to an end point where the final development takes place. Now, you know the exact requirements and have the right strategy to develop and position your mobile banking application.


Third-party integrations can make your application more customer-centric and feasible. It gives a user-friendly app flow while improving customer retention. Third-party integration services include payment aggregators, payment gateways, and much more. Choose them carefully, as they can either make your application boom in the market or be ultimately doomed.


Here comes the final step- THE LAUNCH! Launch it to your target audience after all your efforts to develop the application. But it’s not the end. Just after your product reaches the users, a new journey begins. With this comes new requirements, demands for new features, and much more. You need to monitor your app’s performance and continually work towards improving it every day.

How Mobile Apps Have Created a Financial Ecosystem?

Mobile apps have created a vast financial ecosystem by being integrated with bank accounts. Bank accounts are the center of this universe, and the other additional services are a part of it. Because of the emergence of advanced financial products, this interconnected ecosystem is the breeding ground for transformation.

Even the most prominent financial institutions have been compelled by these developments to provide better digital products and improve customer experiences while reducing costs. Customer expectations have evolved as people get comfortable accessing numerous mobile services.

How Mobile Apps Have Created a Financial Ecosystem?

As a result, there is now a demand for businesses to offer customers effective and uniquely personalized products and services. New technologies have normalized the ability for users to access a range of services within a single app, transforming platforms into multi-service ecosystems.

How much does it cost to develop a mobile banking app?

Mobile app development costs depend on various factors, like the technologies you use and the time you invest. But, it is total development hours X hourly rates of developers. Below is the visual representation of the cost:

How much does it cost to develop a mobile banking app?

Multiple factors affect the overall mobile banking app development cost. Let’s have a detailed look at each aspect:


A wireframe, created with the help of programs like Figma or PhotoShop, is the general architectural design or blueprint of the layout of the banking application. The final wireframe that provides a clear product vision is created after multiple testing processes. A wireframe design typically costs between $8,000 and $10,000.

UI/UX Design

A mobile banking application typically contains information about accounts, money transfers, customer support, an active chatbot, and many other features that can enhance the app’s performance—creating a simple design that can add all the information in one location. A minimalistic design is the right way to move forward. It makes navigation easier, improves customer retention, and keeps them engaged.

App Platform

The mobile banking app’s base platform affects how much it costs. Even while selecting an iOS or Android platform typically has little impact on the overall budget for the app, it is generally preferred to begin with the latter due to its large user base. You can easily choose to have your banking app developed first for a single platform before switching to cross-platform app development once the app starts to acquire some popularity in the market.

Team Size

Cost estimation highly depends on team size. What you wish to accomplish largely relies on your financial situation. If you already have an internal app development team, funding should be within your financial capabilities. If not, you need to outsource your mobile banking app’s development team or individual. Even though they can initially charge you a little bit more, a trustworthy banking app development service provider will promise a better ROI due to their quality of services.

Technology Integration

Technology integration is another vital factor directly proportional to the cost of developing a banking app. Integrating advanced technologies like AI/ML and blockchain is advised, as they can benefit you in the long run. Incorporating these technologies will make your app premium but will increase costs simultaneously.


The more features it will have, the more you will pay. Adding the correct set of features is one of the most essential elements in the development process of mobile banking apps. The development cost will significantly increase as you have more complex or advanced features.


This is the last but ongoing step, even after the launch of your application. This factor is the most critical variable that determines your overall development cost. After all, it’s essential to maintain the quality of your mobile banking app to enable a great user experience. It is necessary to understand that after the launch, the app has user data and actions involved, so application maintenance becomes essential. The app will need routine hygiene checks, ongoing bug detection and removal, and frequent updates.

At every enhancement step of the application, the cost will increase respectively.
