Types of FinTech Apps that you can come across on the market

Today's market responds to customers with many financial needs that can be met by various types of personal finance applications. When you plan to build your own finance app from the scratch, it's worth analyzing two types of apps - simple solutions rely on manual data entry, whereas complex solutions are based on software capable of automatically loading data and processing it to provide insights.

  • Complex Financial Apps - allow users to connect their bank accounts and cards so that all financial data is synced automatically, making it a permanent money management system. Due to the storage of a lot of sensitive data, it requires a limited investment in security.

  • Simple Financial Apps - the risk factor for the basic scopes of application is equal zero, as they are not related to any bank accounts, they are also cost-effective in terms of developing applications for private funds. However, it should be noted that the level of human error is high due to the manual data creation process.

Banking Apps also matter

Traditional banks and other financial institutions are constantly expanding the personal finance management segment. Budgeting features are now available in almost all banking software. Banks and the financial services they provide may become competitors.

Benefits coming from Finance App

Thanks to the revolution of online payments and an innovative approach to banking, more and more people globally decide to start using this type of application because they offer more intuitive and transparent interfaces, which ultimately facilitates the management of personal finances.


Personal financial applications reduce costs by using new technologies, such as Artificial Intelligence and Machine Learning. Most often, there is no need to pay for the budget management application, but if there is a transaction fee, it is relatively small.

Top Technical Requirements to Consider While Building a Finance App

#Authorization and user profile

A user must be able to log in by entering their personal information in order to run the personal finance application. After entering the data, he/she should complete their personal profiles and start using the app.

Since applications store a lot of user data, authorization and security should be given a high priority. At least two-factor authentication or biometrics to protect users' financial accounts from cyberattacks should be implemented.

#Expense Categorization

A personal finance application should include expense categories to help users in effectively tracking their transactions.

#Regular Notifications

Alerts and notifications are key features that help users be aware of the current state of cash and upcoming transactions, such as low balance, upcoming bills to pay, overspending, suspicious transactions and special offers for investing or credit.

#Analytics and reporting

Analytics and reporting are essential to transparently track all user's financial activities. With well-organized data, the user can receive daily or annual reports to analyze income or expenses, view forecasts, etc.

What the Personal Finance App Development Process look like?

There are several key steps of developing a finance application. Below, we'll guide you through:

#Create A Concept Map

At the beginning of your journey, you need to come up with some custom and unusual idea on finance app. Consider scalability, global reach, and user trends in your decision-making process. And keep in mind the unique selling proposition of your FinTech product.

#Conduct a Market research and Deep Analytics

During this stage, it is necessary to focus on getting to know your target audience in detail. Find out not only what their needs are, but also what their expectations are. It is important not to forget to study the market itself in order to understand in what direction the industry may change in the future and competition, in order to know its strengths and weaknesses.

#Choose The Right Tech Stack & Platform

Choose the most tailored tech stack for your project based on its scope, programming languages, thread detection technologies and app architecture. Also, decide what kind of tools and platform (Android, iOS, both?) is the most suitable for your app, based on whether you work with an in-house development team, freelancer or outsourced partner.

#Proceed to Development Process

At this stage, when the technology stack is focused on adaptability, debugging capabilities, scalability and security, the development team should determine the desired functionalities of the finance app. 

This phase includes the technical specifications for creating the application and the product information model.

#Design your Finance App

Remember about the unique proposition of your FinTech product - here the key to success is also to create a unique Design.

The UX/UI design must be well organized, transparent, and above all intuitive and easy to manage for users.

At this stage, it is also worth following Icon Design Trends to find out what visual elements are currently in demand and what is best to implement when creating the interface of your application.

#Remember about Testing and Launching

Testers should be involved in this stage, due to the need to refine the personal finance app before its mass premiere. Testing gives you the opportunity to remove any errors to make the user experience more intuitive and satisfying.

The next step is to prepare the first MVP version of your application to collect feedback and opinions after sharing it with a selected group of users. It provides a lot of valuable data about users themselves, but also generates the first base number of users.

#Maintain your App Regularly

After launching the full version of the app, you should maintain it regularly to keep your digital product free of serious bugs and respond to current market demands and user expectations. Thanks to this, you will be sure that your application works flawlessly while offering services at the highest level.

Challenges that must be overcome when building a personal finance app

Companies must take into consideration that they will have to face many challenges that will stand in their way to success in building a financial application. The most enduring challenges include:


Compliance with regulations and regulations set by the government is the most difficult challenge for mobile FinTech providers. Some of the regulations that need to be considered can be found in our article: Security Best Practices for FinTech Application Development.


Companies and startups based on financial technology usually need external investment so that their applications can progress the development process. Determining the potential and real return on investment, as well as cooperation with mobile app developers, are the basic elements for budgeting and fundraising.


Fintech companies process sensitive personal and financial data, so strict security protocols are essential, as the FinTech industry is vulnerable to cyberattacks.


Another challenge is developing an aesthetic and clear user interface. The application must be user-friendly, with a simple yet intuitive approach to its basic functions. A personal finance app should keep all the users engaged.
