Step 6: Update your Application

In the world of fintech, there are always new features and elements that are incomparable and exciting at the same time. With the evolution of technology, you have to update your finished application regularly.

Essential Tech Stack for Fintech App Development

Techstack isn’t just a set of tools that are used to develop a fintech app, but choosing the right tech stack that aligns with your business needs is a plus point. Let's have a look at the advanced tools and technologies that can be the best fit according to your finance business.

Web Fintech Apps with React and Node.js

One of the greatest combinations for finance web applications is undoubtedly React and Node.js. Just consider the volume of real-time data that finance apps must handle. Since the backend is carefully managed by Node.js, this is not a problem. React is a perfect fit for the timely updation of the financial data on the frontend without requiring a refresh.

Native iOS and Android Fintech Apps With Kotlin and Swift

You'll probably have to decide between native and cross-platform development because finance apps tend to favor mobile technologies. Some of the most popular iOS and Android frameworks for developing native financial mobile apps are Kotlin and Swift, if you choose to go native these apps are more expensive due to some top-notch advantages such as the ability to operate offline. For every platform, a separate codebase is kept.

Cross-platform Fintech Apps with Flutter & React Native

A better option is provided by cross-platform apps, which reduce development time and expenses while enabling you to create and manage a single codebase that functions flawlessly on several platforms, including iOS and Android. Although technologies like Xamarin, React Native, and Flutter are frequently used for cross-platform development, many teams prefer React Native due to its effectiveness and possible cost savings of up to 50% because Xamarin and Flutter are typically more expensive to build and maintain. Developers use reliable software development tools for teamwork, version control, and project management in addition to your fundamental frameworks or programming languages.

Top Fintech Market Trends Shaping the Industry

When you work on the development of a fintech application, it is necessary to have a clear understanding of the features and functionalities that will take your app to market successfully. Let's have a clear picture of the ongoing trends.

1. Increased Banking Mobility

Banks are feeling the strain from fintechs and are increasingly relying on smartphone and web apps to deliver key services on the go. The epidemic has hastened this tendency, with neobanks challenging the status quo of in-person banking.

2. Financial Inclusion and Niche Fintechs

Financial technology is helping underprivileged people, minorities, and people of all ages have access to more inclusive services. For example “SilverTech”, a company that only services seniors and helps them manage their healthcare expenditures and retirement plans.

3. API as a Product

Along with allowing connectivity and integration throughout the financial management platforms and Open Banking is a driving force. APIs are now becoming a useful product that firms like Plaid, Galileo, and Marqueta monetize.

4. Blockchain and Smart Contracts

Blockchain has removed many of the hurdles to financial transactions which includes authorization from intermediaries such as banks. Using blockchain, smart contracts allow for the secure and transparent exchange and storage of data.

5. Growing Role of Alternative Data and Big Data

Fintechs are enriching their client data with alternative data such as social media activity or wearable devices, allowing previously ineligible customers to get access to financial services. Big Data management is a big challenge for fintechs due to the volume of information collected.

6. Embedded Finance

Embedded finance refers to the integration of financial services such as bill payment, insurance, and loans into non-financial systems. Embedded finance services are especially useful for e-commerce platforms since they provide a seamless customer experience without leaving the app.

Popular Types of Fintech Applications You Should Know

Here is a list of FinTech mobile app types that you can choose from when developing your own:

• Payments/payment gateway
• Mobile banking
• Investment and wealth management
• Lending and borrowing
• Personal finance
• Insurance
• Regtech software
• Trading solutions
• Digital wallets

You should thoroughly evaluate your target audience, the category your fintech app fits under, and how they will use it before developing it. Let's take a closer look at some of the more common varieties.

Insurance Apps

Many of the cumbersome procedures and red tape associated with applying for various kinds of coverage, from life insurance to property and pet insurance, are eliminated by insurtech apps. Users may purchase insurance policies, submit claims, and receive immediate customer care assistance using these fintech apps. InsureTech systems use the Internet of Things (IoT) and AI-powered analytics to better assess risk and provide individualized insurance plans based on a person's risk profile and lifestyle.

Personal Finance and Budgeting Apps

Traditional financial institutions are known to be disliked by millennials because it is predicted that today's generation is more likely to have the maximum growth in terms of personal wealth. And with the help of these applications, money management is becoming a piece of cake. By taking advantage of these platforms, users may better understand their spending patterns, make appropriate plans, receive tax guidance and manage their money.

Investment Apps

Investment applications are becoming more popular, much like personal finance. An increasing number of people are trying to find a different source of income because over 80% of millennials say they do not anticipate being able to retire. For those with little prior knowledge, investment apps provide a simple and cost-effective way to build and maintain investment portfolios, get expert advice, or use robo-advisors to automate investment decisions.

Lending apps

Peer-to-peer lending apps give small enterprises and individuals new methods to apply for loans directly from other users. They have more appealing options, such as borrowing smaller sums of money that they can repay interest-free, rather than taking out bank loans and incurring exorbitant interest rates.

Cryptocurrency Apps

The entire process of utilizing virtual currency in daily life is made easier by these programs. Cryptocurrency apps are similar to other fintech apps in many aspects; however, they employ cryptocurrency coins rather than cash. For instance, you can exchange ordinary money for cryptocurrency via an exchange app or you can store coins in your cryptocurrency wallet exactly like you would in a standard digital wallet. To ensure you're properly handling these financial aspects, it's crucial to take into account how an app manages taxes on cryptocurrency transactions.

Not to get confused about the utilization of the latest technology and tools, we have gathered some details about the best examples for the fintech applications that are ruling the fintech industry on a next level.

Why Your Business Needs a Payment App Solution

Better Cash Flow

By taking advantage of the fintech mobile app development, assisting with every transaction is traceable, while checking in and checking out is never easier than ever before.

Reduced Workforce and Cost

Not only for the established businesses, but small businesses are able to leverage streamlined services by cutting transaction costs, surcharge fees, hiring staff to monitor every single transaction, and more. By taking advantage of these services, businesses can save a lot of money and effort.

What Does It Cost to Build a Fintech App?

Numerous financial apps, from tiny but powerful MVPs to Open Banking solutions that access data from banks around Europe, have been developed and released by our Appingine team.
