How to Develop a Secure Fintech App in 8 Simple Steps?

Fintech application development is not an easy task because it requires a detailed analysis of the prime purpose of the construction of the app, which is financial. Therefore, it is crucial to ensure that the building process is carried out without any bells and whistles.

Below are the 8 Simple Steps To Building A Fintech App!

3. Plan a Budget Beforehand
4. Build User Personas
5. Focus a Lot on Visual Experience or User Interfaces

1. Analyze the Type of Fintech App to Build

There are numerous fintech categories available on which apps can be developed because banking technology holds various applications for carrying out different tasks. 

Note: The categories of financial apps are discussed above. In case you need to know what those are, scroll above to see them. 

Therefore, any project we build will directly impact the user who uses the interface and leads who develops it. Below, let us quickly see a few of the categories and how difficult it is to turn them into digital.

• Personal Banking & Insurance: To develop these apps is difficult, expensive, complex, and time-consuming. Because, not only do they require an interactive user interface for admins to gain insights on user accounts, but users must also be able to make changes to their private accounts with ease.

• Loan Apps: Compared to the above-mentioned domain, these apps require less effort but high security because of the loan applications that need to be shared across the internet. 

• Investment Apps: These apps require less manual effort and technology to build as they only display the investment information to users that guides them on what stocks to buy and lend. So, an API can be more sufficient for its development.

2. Do a Market Research

The days are not like they used to be during the 80s when individuals had to walk past the doors to get their passbooks printed. These days, even our grandparents know how to use a financial service using an iPad, such is the fintech growth. 

But, just not sticking with this point, one must really do a survey as to whether such apps will survive in the market because a recent report says that 60% of individuals are least likely to operate digitally for their payments. 

White-label SEO services ensure that market research reports are visible in search engine results when potential clients search for industry-specific insights. Plus, to make your fintech app stand out from the rest, you will need to audit your competitors’ work and pay a close eye to their features used and the benefits offered. 

In turn, these rich analyses can help you build an innovative fintech app. 

3. Plan a Budget Beforehand

Planning a budget for fintech mobile app development or web can come somewhere between $50,000 to $300,000. Considering that the range is very high, the complexity of the app and the features it includes also raise the budget bar. Therefore, it is necessary that you either recruit an experienced fintech app developer to design your product or hire a development agency.

Any newbie in the field or inexperienced and unskilled personnel can hamper your fintech app ideas leading to cutting corners of security, which many users would not recommend or like. Because a recent survey shows that over 65% of individuals prefer top-notch security in their fintech apps. We would suggest that you simply use a fintech and banking API for doing this work.

4. Build User Personas

While designing fintech apps, it is a mandate that we understand who our target audiences are and how they will react when a product is launched. And thus, user personas can be of great help in solving this difficulty for the business development team. 

A user persona is none other than a fictional character who acts as a target audience and participates in interviews, surveys, and other research analyses to help teams visualize what the real audience would feel and think. 

In turn, helping mobile and web developers to concentrate on the areas they missed and technical flows to improve. And, to build a user persona, the following steps can be taken into consideration:

• Conducting quality research
• Secondary quality research
• Organize all the findings
• Visualizing the personas and iterating if needed 

5. Focus a Lot on Visual Experience or User Interfaces

Did you know that in the year 2021, over 60%+ users uninstalled the fintech apps just because their onboarding was not relevant? Hence then, it has become the main motive of many developers to map the user scenarios and design an interactive layout for eternal retention and engagement.

Well, how can you do this?

• Start by creating user personas as to which target audience wishes to experience what data on their screens.
• Do a market survey on the likings and dislikings of the app’s intro details.
• Iterate often the interface and look out for security errors if any. 
• Always think in the shoes of users and then make decisions on analyses and techniques.
• Add investment goals and plans for gaining their interest. 

6. Decide on the Features & App Requirements

Just like how the app’s interface plays a vital role in sticking customers to the app, what features to include within the application also needs to be prioritized. Some of the features to keep in mind would be

• Color of the Interface
• Look and feel of the app
• Icons and navigation panels
• Storage capacity and a few others

Similarly, requirements like the ones below can ensure potential customers use your fintech apps for a very long time.

• E2E encryptions and user authentication
• Payment integrations using any banking APIs
• AI learning and notifications
• Dashboards and reports

7. Choose the Right Tech Stack

If you are a developer who is looking for the best ways to develop a fintech app, then you must learn that an appropriate technology stack must be put into place that offers great functionality. Like,

• Framework: Whatever framework you use for both front-end and back-end programming, it must match with the programming language and your skill set.

• Programming Language: Javascript, Swift, and Kotlin are some of the popular programming languages used to develop fintech Android and iOS apps. 

• Database: To store customers’ information and retrieve other data, relational databases can come in handy.

• Banking APIs: Also known as Fintech APIs can fasten your app development process by integrating real-time features that are required.

8. Develop Launch Strategy

A launch strategy does not include preparing for product launches or connecting with influencers alone, instead preparing a timeline that would include all the app checks with regulatory parameters. Meaning, whether all the attributes are in the correct place and whether the app complies with industry and legal requirements.

Imagine you are building a finance app, and for its successful operation and for users to exchange funds or make deposits, you would require a banking license. But, let me tell you that the licensing agencies are often slow and there is no guarantee, you will receive the license soon. Therefore, this parameter has to be on your checklist before ramping up for the launch.

Another example of a launch strategy is the soft launch for your finance app which will help drive the product to success by checking all the missing factors and making improvements if necessary. These types of launches give the opportunity to test bugs, collect user data, have a note of marketing spending, and take the app to the next level. Custom app designs are crucial for tailoring the user experience and ensuring the app meets specific business needs.

Finally, here we are at the end.
