In today’s world with the greatest innovations, mobile applications have become an essential part of our daily routine. Thanks to technological advancements, you can see a plethora of useful applications that make your daily life easier. Recent statistics show that 88% of consumer-bank interactions will happen through smartphones by 2022. With the mobile banking app, you can make payments and check the balance on the go with a simple click. Not only does it help you check credit scores with ease, but you can also break down your expenses and be in the know how much you’re spending each month.

In addition to that, completing financial transactions through an app by simply tapping a button attracts users' attention. According to Statista, 90% of US-based users opt for mobile banking apps to check their balances, 79% of them view recent transactions, 59% - pay bills and 57% - transfer funds. As for UK users, 71% of users will have used apps for banking by 2024. With that in mind, financial organizations need to adapt to mobile market trends to keep up with the growing demands of digitally-savvy users. Moreover, 82% of mobile banking users believe banking apps can improve their financial situation. Let’s dive into the details below to discover how we developed a mobile banking app.

What exactly is a mobile banking app?

From its name, a mobile banking app is a mobile solution used to access the bank account from everywhere and at any time. Not only is it suitable to complete transactions directly from your mobile device, but you can also stay on top of your finances and pay certain bills when it's time. Moreover, a mobile banking app can deliver different types of services. Let’s highlight them below:

  • Account information access: this category of services allows bank customers to view their account balances and statements, review transactional and account history, keep track of their term deposits, etc.
  • Transactions: this category of services allows bank customers to transfer funds, to transfer money between their own accounts, pay bill payments, etc.
  • Investments: this category of services enables bank customers to create a plan in accordance with their current needs and future goals. Not only can they manage their portfolios, but they can gain insight into their investment portfolios.
  • Support: this category of services allows bank customers to request help when they face any issue and need support from experts.

Why do you need a mobile banking app?

Currently, almost every user owns a smartphone and spends more than 7 hours every day on it. This means mobile apps are becoming the most powerful way to stay in contact with the target audience. Here are the reasons you need a mobile banking app:

  • You want to launch an innovative banking solution that better protects users’ privacy, financial information and identity.
  • You want to provide immediate access to users’ accounts and meet their needs online.
  • You want to simplify the process of keeping track of finances and help users improve their financial wellness.
  • You want to increase brand recognition through the mobile banking app and strengthen your position for the future.

What’s the idea of the project?

Today we have no doubts about mobile apps’ popularity. Not only do people use them to shop online or play games, but they are also essential in making online transactions and checking account balance. Moreover, in light of COVID-19 shutdowns, remote work and social distancing, the use of financial apps and mobile banking services has increased by 72%, deVere Group reports. Another source states that the rise in fintech app use comes amid a broader growth in digital technology use. Sounds impressive, right? Having vast experience in the fintech domain expertise, we decided to create a mobile banking app that offers a variety of options such as paying bills online, viewing and checking account information, transferring money from one account to another and many other banking apps features. Moreover, it has more powerful security features that help prevent any suspicious activity.

Development of the mobile banking app

Below we provide some critical information on how we developed a mobile banking application. Keep on reading!

Development of the mobile banking app

Team

To create a mobile banking app, we need a team that consists of the following specialists who can bring an idea to life:

  • 1 Business analyst (BA)
  • 1 Project manager (PM)
  • 2 UI/UX designers
  • 2 Front-end engineers
  • 2 Quality assurance engineers (QA)
  • 3 Backend engineers
  • 1 Android engineer
  • 1 iOS engineer

Methodology

When developing a mobile banking app, the team opted for agile software development methodology based on the following reasons:

  • It was easy to prioritize the client’s needs and change the requirements.
  • We could adapt to any change in the client’s requirements.
  • We managed to deliver a ready product that provided value at the end of each sprint.

In the end, the team implemented 24 sprints during which it completed the project and attained established goals.

Development Process

At the very start, a Business Analyst conducted a meeting with the client to elicit all the essential information about the desired product. Based on that information, the Business Analyst documented all the client’s requirements that helped the team understand clearly the future project from the client’s perspective. Only by gathering all the crucial information about the potential user roles, their permissions and activities within the banking application could we create a functional specification that outlines a product's intended capabilities, appearance, and interactions with users in detail for a team of software developers. In addition to that, we came up with the following features of the banking app:

  • multiple ways to log in;
  • alerts and notifications;
  • security features;
  • account management.

Thanks to this information, a Project Manager provided a preliminary estimate to the client and suggested the roadmap for the development process of the future mobile banking app. Once the client approved the preliminary estimate, we divided the planned scope of work (so called Backlog) into smaller parts - 2-week sprints. We implemented 24 sprints during the period of 12 months. Before each sprint, the whole team of designers, front-end and back-end software developers, QA engineers reviewed which feature or features from the backlog they were going to develop and deliver by the end of each sprint. Once the mobile banking application was 100% bug-free and worked flawlessly, we launched it and made improvements to keep the users satisfied with the capabilities the app offers.
