There is a strong need for fintech applications among users of different ages, locations, and social characteristics. Therefore, if you decide to create a fintech app, your business will be more successful. The demand for mobile fintech apps will only grow over the years, and after a while they will completely replace outdated financial management solutions. Today, fintech companies are separating all types of transactions that were traditionally performed by financial institutions and focusing on niche financial services, making them as simple and user-friendly as possible. Many companies have long made sure to make a mobile banking app, and now they are more competitive than those who have not yet done so. Fintech is now used for a range of financial practices, such as money transfers, depositing checks via mobile banking, bypassing the bank to apply for a loan, dealing with your savings, or raising money for a startup. And it's all without human assistance.

What is Fintech, and How Does it Work?

Before you can develop a fintech app, you need to understand the basics. Fintech is the technology with which businesses and financial services manage the financial aspects of business. Companies use fintech to compete with traditional financial institutions for customer funds. Fintech has come very close to the consumer of financial services over the past decade, this is because it is at the core of online transactions. Before you start to make a fintech app, remember that consumers want easy access to financial services, free payments and fast loan approvals, Fintech helps consumers solve their needs and problems quickly and with minimal effort. Fintech apps and neobanks are already firmly established in the financial system, and are having a significant impact on traditional financial institutions.

Neobanks, i.e., online banks that operate without physical branches, are in great demand around the world. They optimize many processes: paperwork, staff work, collection, storage of money, data processing, so they can offer clients more favorable conditions. According to statistics, the use of online banking will grow worldwide in the upcoming years. The largest market is Asia, which is predicted to have nearly 1 billion active online banking consumers by 2024. So, now is a good time to start a mobile banking app.

Fintech closes the analytics segment, allowing the right data to be collected and audited. It introduces a set of anti-fraud measures aimed against fraud in banking or Internet transactions. Developments in fintech projects allow us to process more data about the customer, such as where and how they pay with their card. Then, based on this, banks can offer users interesting perks and other rewards. To successfully develop an online banking application, you need to take care of a good data protection.

Every year we see more and more fintech startups that make products related to the collection, analysis, and big data processing. This may be information about consumer preferences, search queries, the geography of payments, etc. Big data processing helps personalize offerings, tailoring them to market demands and customer categories.

How to Create Fintech and Banking Apps?

In this section, we have prepared the basic steps for developing a competitive fintech mobile application that can meet the needs of the most demanding customers. Developing any financial platform requires an experienced team of programmers, analysts, designers, and engineers who, with a thoughtful approach, will be able to carefully implement your idea. With your money and reputation at stake, it's important to plan the project carefully and be aware of all the pitfalls. Let's take a closer look at the basic steps of fintech and banking app development.

Choose a Niche

To begin with, you need to decide on the niche in which the software will be used. You need to analyze and define your target audience, and study the direct competitors in the market relating to the financial application.

Find your niche in the market, analyze existing solutions to create a unique, useful and advanced solution for users. Research market needs, especially in countries where good fintech and banking solutions are lacking, to increase the chances of success.

Ensure Legal Requirements

You need to think seriously about the legality of your financial application. Each country has its legal and regulatory requirements in the financial sector, so your app must comply with privacy laws and other legal regulations. In addition, your application must comply with various financial standards that differ from country to country, such as KYC, PCI DSS, AML, and others.

Hire a Dedicated Financial App Development Team

After defining the idea and goals of a financial application, you will need specialists to develop it. There are different models of cooperation, you will need to choose one of them, depending on your goals and the complexity of the project implementation.

For a complex and large-scale project, it is better to assemble an in-house team, and for simpler ones, choose outsourcing or freelancers. When researching companies or individual developers, carefully examine their portfolios and reviews.

Define Your App?s Features

Your development team should consider and identify the banking mobile app features that need to be added to make your financial application work effectively. Start defining the most important features and add them to your minimum viable product. Then, as required, you can add other, more advanced features.

Choose a Technology Stack

There are many technologies and programming languages for developing fintech and banking applications. The technology stack will depend on what type of financial application you select: native application, cross-platform application, or hybrid application. If your team consists of experienced developers, or if you have hired an outsourced software development team, they will advise you and help to choose the right technology stack.

If you are developing an Android app, it will be developed in Java or Kotlin. An iOS mobile app will be developed using Apple XCode, Objective-C, and Swift. Developers most often use React Native and C# to create cross-platform apps. Various frameworks are used to create hybrid apps: React Native, Flutter, Ionic, Xamarin, and others.

Think of a Superior UX/UI Design

Your designers should start building mobile banking apps for fintech with an attractive visual design. A UI/UX study should be conducted to work out the navigation of the app and a user-friendly interface. The interface of the financial app should be intuitive, user-centric, and pleasing to the eye. You have to make sure that all the functions the user needs are intuitively accessible on the dashboard.

Develop Your App

After designing the financial app, your developers should move on to implementing the technical part of the project. In addition to communicating with the developers, you will work with QA experts who will test the application and advise on what can be changed and improved. The result will be a minimally viable product with basic fintech app features and components. This is enough to obtain feedback from users and also to attract investors.

Test Your App

Before a financial application is released to the market, it should be thoroughly tested to make sure it is error-free. The app must work properly, and the QA team needs to fix any problems and vulnerabilities as quickly as possible to do so. Your experts can use both manual and automated testing to check the application for errors.

Launch Your App

After successfully testing the financial app and fixing bugs, you have to release it to the market. After releasing the app, your team must make sure that users are happy with the solution and its features. You need to review user feedback regularly and make necessary improvements to the product. For fintech and banking applications to be competitive and evolve, they must be constantly updated and improved.

Fintech and Banking Mobile App Features

App features that can make it easier to use and help users in various ways play a considerable role in the success of customer retention. If you want to succeed and get good results, you should know about the main features that will help with customer retention. By implementing advanced features in your app, you will achieve increased user retention, increase company loyalty and increase the number of app installs. As consumer needs grow, it's important to consider adaptable features to increase customer retention. We have prepared must have features for you to ensure the best user experience.

Biometric Security

To protect consumers' money, your financial application must be highly secure or no one will use it. To achieve a high level of application security against unauthorized access, we recommend that you integrate biometric authentication into your solution. The most suitable options for biometric protection are fingerprint access, or facial recognition. It is impossible to reproduce a user's face and fingerprints on the Internet, so hackers won't be able to steal anyone's money. Furthermore, biometric authentication, in addition to the high level of security, is convenient and fast.

The Nubank mobile app has introduced biometric protection, which is designed to protect users from hacking and combat credit card fraud. The app's biometric protection includes FaceID and VoiceID features. Through the use of an advanced biometric security system, Nubank users can be sure of keeping their funds and personal account data completely safe.


Gamification is an interesting feature that includes game elements and reward systems that aim to make using the app fun. Thanks to this, you can not only retain customers, but also attract new ones. Gamification includes many elements, such as badges, leaderboards, points, completing tasks to earn rewards, setting goals, and tracking progress.

One of the exciting gamification techniques is the goals and objectives feature. This feature will increase consumer satisfaction and allow them to improve their financial well-being. To increase consumer interest, the option to set savings goals and be rewarded for achieving them can be added to the app. The Qapital financial app gives users the ability to set savings, spending, and investment goals. Qapital also has visualization functionality.

Data Visualization

Users of your fintech app should receive detailed charts and visualizations of all financial-related information, with the ability to select a specific period of time. The app should present users with financial data in an interactive way, expenses, income, investments, and so on. Visualization is undeniably important to ensure user experience and consumer retention.

It is an undeniable fact that users absorb information better in graphical form and can track trends and patterns more easily. In the Mint app, for example, users see their bank balances in a chart and can easily analyze their income and expenses. When providing data visualization, developers must optimize it for smartphone screens by selecting the right layout, colors, and fonts.

The cashback feature allows users to receive a percentage of the money they spend. Cashback is no longer just a nice bonus, but an obligatory feature of any successful fintech banking apps 💡. Consumers like apps in which they can benefit from any transactions they make. This feature is most often used by neobanks. This is pure psychology, if consumers see that they can profit and save their money, it will be a definite advantage for them, and the chance that they will use the app will increase. Cashback increases user interest and retention rates for your banking and finance app.

MoneyLion offers customers a lucrative rewards program. Users of the app receive cashback for purchases of groceries, daily necessities, prescriptions, and so on. When users make a purchase in the rewards tab of the mobile app using their MoneyLion debit card, they earn points, which are then redeemed for cashback into an investment account.


Chatbot is a great feature with which you can improve the user experience of your app. AI-driven chatbots provide 24/7 instant support to consumers, answering thousands of questions at a time. The best fintech apps have embedded chatbots into their apps to assist users with personal finance and other issues.

For example, Robinhood has implemented a chatbot in its trading & investing app that helps automate many processes and improves the user experience. The chatbot saves time for employees to solve various issues, as well as speeds up user interaction with the application.

Two-Factor Authentication

Two-factor authentication is used to protect the personal data of fintech application users and make it harder for hackers to break in. In today's world, cracking a simple and short password, which most people use because it is easy to remember, is not very difficult. With two-factor authentication, even if a hacker passes the first layer of protection, he will have to get access to a phone number or email, which is much harder.

Chime requires app users to set up two-factor authentication, to securely protect your account from intruders. Two-factor protection is not a panacea for hijacking a financial account, but it is a reliable enough barrier that seriously complicates attackers' access to application user data and to some extent eliminates the shortcomings of classic password protection.
