Depending on which FinTech app you choose, banking apps can offer a variety of features, such as remotely checking deposits, travel money, budgeting tools, and international account accessibility.

Lending app

A lending app can be used to take out a loan or invest your funds. Today, these tools are becoming more popular, with brands like Lendable and Moola offering lending services. These apps allow you to choose your amount, the interest rate, and the term length. The lending app connects you to a network of other investors and borrowers. You can also use it to take out a loan and invest your funds in peer-to-peer lending or crowdfunding options.

Investment app

You can use an investment app to diversify your portfolio, find new investment opportunities, and track your portfolio performance. Many FinTech investment apps are developed for experienced investors and offer access to premium features, like stock picking and portfolio analysis tools.

What Are the Key Features of FinTech Mobile Apps?

From budgeting tools to personalized advice, you should look out for various features to ensure that you get the best out of your mobile finance experience. 

Personal account

Before building a FinTech mobile app, it is important to consider the type of account the app offers. 

Most mobile apps provide users with a basic account, however, FinTech apps specifically focused on personal finances provide a personal account that allows users to link multiple bank accounts, making it easier to manage their finances. Moreover, they can also see all of their finances in one place, making it easier to track and manage funds.

Payment gateway

It is essential to consider the payment options provided by the FinTech app. Certain apps allow users to make payments to other individuals, while others will give them the option to pay for goods and services. Whether it’s a cryptocurrency or a mobile banking app, a payment gateway is a must.

History of transactions and interactions

This feature allows users to track all of their finances and will inform them of any potential issues they may face. This includes keeping track of spending and any budget that users have set up. The main goal of this feature is to monitor finances and make adjustments when needed.

Customer support

Users always have questions or face some issues while using an app. Make sure you have a support team ready to process these requests 24/7. A quick response can go a long way in reassuring your users about the quality of your app and its support. A solid FAQ is also a must-have for an app. 


As technology progresses, FinTech apps are beginning to offer the use of chatbots. Chatbots are artificial intelligence systems that can help with various functions within the app. This includes helping users to track their spending and informing them of any issues with their finances. 

Personal spending analytics

FinTech apps also provide analytics that enables users to control their spending. They can see how their spending changes over time, allowing them to make adjustments as needed. This can be useful for those who want to use finance as a tool to manage their spending.

5 Challenges in Developing FinTech Mobile Applications

Let’s run over five of the biggest obstacles when building a FinTech mobile app and how to surmount them. By understanding and preparing for these challenges, developers can create successful, secure, and compliant mobile applications that meet the modern consumer’s needs .

Fintech App Security

The main challenge developers usually face is how to develop a FinTech app that will be safe for users. When building a FinTech app, developers should begin with a security-first mindset. This means they should understand the risks associated with the app and find ways to mitigate them. 

In addition to minimizing risks, developers must follow their organization’s security guidelines. All financial organizations must comply with a set of regulatory security standards, such as the Payment Card Industry Data Security Standard (PCI DSS). This standard outlines the technical, administrative, and physical security controls that financial organizations must implement to store, process, or transmit cardholder data.

Focus on Target Audience

FinTech apps are used by various people, from consumers to businesses. As such, developers should focus on the target audience for their app. This means that they should consider the needs and desires of their target audience and their demographic and psychographic data. For example, an app designed for college students should include features such as social media integration and push notifications. In contrast, an app designed for small business owners should include features such as inventory tracking and stock management. 

Once the target audience has been identified, the next step is understanding  their habits and preferences. This can be done through market research, such as surveys, focus groups, and interviews. 

Cyberattacks protection

Protecting against cyberattacks is one of the top concerns among FinTech developers. While security is an ongoing process, building it into the development of a fintech mobile app lifecycle is essential. Developers must understand their app’s risks and vulnerabilities and then put security measures in place to mitigate them. This is especially true for FinTech apps that store or transfer sensitive information, such as payment apps and apps that store personal data. It is  of utmost importance to set up the system so it can quickly respond to data leakage.

Building the right architecture

Another challenge that programmers usually face is how to develop a FinTech mobile app with the proper architecture. The architecture is the foundation upon which the app is built. It can be likened to the house frame in that it provides the foundation, structure, and support for the rest of the app. 

If the architecture is not built correctly, the rest of the app will be built on a faulty foundation, which could lead to a less-than-optimal app. This could mean that the app is not scalable, not cost-effective, or perhaps it cannot meet regulatory requirements. In order to build the right architecture, developers must understand the needs of the app and the available resources. 

Good usability

FinTech apps are used by people from all walks of life and with many different backgrounds. This means that apps must have a user-friendly interface and be easy to navigate for every customer, regardless of their knowledge level or proficiency with technology. To ensure the app is easy to use, developers can employ several usability testing techniques. These tests can identify any usability issues and then determine how to fix them. Developers should also use empathy mapping, a technique that helps designers and product managers think about how their target audience will use their app. 

App Development for FinTech: How Much You Should Expect to Spend?

Before you invest in the development of a FinTech application, it goes without saying that you want a viable return on your investment. To this end, getting  a handle on the costs of creating an e-commerce app is important. However, the final price depends on the type of app you want to make, the level of complexity, the technology stack you plan to use, the type of skills required to build the app, the scope of the project, and the timeline you have in mind. On average, building a FinTech mobile app solution will cost between $45,000 and $300,000.

Here is a list of specialists needed to develop a FinTech mobile app:

  • Back-end developer
  • Mobile app developer (Android and iOS)
  • QA team
  • Project Manager
  • UI/UX designer
  • Product Analyst
  • Business Analyst
