Choose the Best UI/UX Approach

Two Things to Consider When Creating a User-Friendly Fintech App

UX Research

Discover user requirements, patterns, behaviors, and the most popular fintech app features. A few desirable user personas can assist you in quickly visualizing your target audience, and you can then incorporate your research into your fintech app business plan correspondingly.

Wireframe Design

A wireframe is more like a layout in which designers plan out which features to put in where.

Form a Team

A team of tech professionals is required to create a fintech app. If you decide to hire dedicated experts, you will need them for the following:

  • UI Designing
  • App development (with Node.js, Java, and Swift language skills)
  • Application testing
  • DevOps engineering

Determine MVP Scope

Your fintech app must have sufficient features to entice early customers who can later offer feedback, which is the primary purpose of an MVP (minimum viable product).

  • Conduct market research and make sure you have enough information about your product.
  • Analyze which features are essential in your fintech app with your team.

Technology Stack

Frontend Tech Stack

The client side, or front end, is where users interact directly. HTML, CSS, and JavaScript are commonly used to structure, customize, and add dynamic functions. However, developers frequently used frameworks to speed up the development process. Each framework has a distinct set of advantages and disadvantages. Popular frameworks include Angular, React, and Vue.js.

Backend Tech Stack

The back-end tech stack is in charge of information/data logic, storage, and processing. Some programming languages used in the fintech industry are Java, Kotlin, Python, C++, and C #.

Essential Features of Fintech Mobile App

Data Security Regulations

Financial data/information is more frequently vulnerable to theft and cybersecurity threats. As a result, app developers must exercise extreme caution and ensure data security.

Here are some critical security features to be aware of:

  • To avoid misuse and to protect against unauthorized access, the app should include two-factor authentication.
  • Only the last three digits of a credit card should be visible to reduce apparent risks and keep credit card information secure.
  • If a user wants advanced features, fingerprint, facial, and voice recognition can be included.


A dashboard is an overview with visual representations where users can check their spending and payment history.

Push Notifications

The push notification feature creates value for your financial app. It alerts your users in real time and keeps them up to date on any payment changes or special offers.


Personalization could mean various things to various individuals. It could be changing the font size, dashboard settings, or switching from a light to a dark theme, among other things. On the other hand, adding a personalization feature to your financial app is a great idea.

Final Words

Users are increasingly selecting digital finance solutions, which is why the fintech industry is expanding. In 2023, developing an innovative financial solution is a smart option.
