Do you also aspire to create an app for investment business? Keep reading to know what it takes and what it gives.

What is an Investment App?

An investment application is a mobile application intended to spread publicly traded business information. Both new and seasoned investors will monitor their investments in the stock market and other financial markets through the investing app. These investment applications help investors save cash and boost their investments with a range of flexible resources at low app fees.

There are various types of investing trading applications, such as

  • Banking apps: The vast majority of modern consumers tend to use online banking and make deposits, so the software solution can be a workaround.
  • Acorns investing apps: Acorns app simplifies investing processes through the unification of brokers and advisory services.
  • Exchange-traded funds apps: This category is for all those investors who are interested to invest in stock markets widely.

So, if you are in the investing business and connecting investors with the financial institutions and stock markets, this is the high time you get software built for stock funds and digitize it completely. Why? Read the below section.

Why Should You Digitize Your Investment Business?

Popularity. Because the first thing comes first. The madness for the online investing market, purchasing & selling stocks, controlling investments, and preparing savings – is at the peak. Not only locally but globally, more and more customers are trying their hands these days in stock markets.

Hard to believe? Look at the graph below, displaying the distribution as of January 2020 of countries with the world’s biggest financial exchanges.

Stock Markets Worldwide Stats

In the United States, capital exchanges accounted for more than 54 percent of foreign stocks. Japan, followed by the United Kingdom, was the second biggest nation by stock market share.

Do you still need more reasons?

An array of Niches. You can develop a beginners’ educational portal, or establish an alternative for those who want to open a retirement account, or even sell cryptocurrency purchase gift certificates. So many choices, isn’t it?

Nominal Cost. Those who are not professional investors, but want to invest in the diversified portfolio – banks, mutual funds, and investing agencies are charging crazy premiums to frighten the regular workforce. While a comparable job is performed by internet investing companies but at a nominal rate. This will encourage more customers to invest in your investing apps.

To be practical, let’s pick a few examples – Robinhood, M1 Finance, and Stash. These investing companies have started a new trend that allows traders to buy fractional shares. By this move, anyone is now enabled to join the trading platforms game using their worthwhile apps.

How to Create an Investment Mobile App?

Below are the five steps that you need to follow to end the concerns about how to build a trading platform and an effective mobile investment app.

How to Create an Investment App

  1. Plan

    The banking services you want to have and the risks you are prepared to take, you need to think out – which is your first step. You might want to contact your financial planner for the same cause. You would also need to select the ETFs that you want to use in your stock buying app at this stage.

    For example, Robo-advisor for investment portfolios is in a trend. They work well with those who need expert advice at a fair price and those who are willing to transfer the administration of funds to third parties. So, plan out accordingly what you need and how much risk tolerance you can afford.

  2. Prepare Business Models

    You need to create your small business model at the point of financial planning. How much will you charge for your services? How much do you want to earn from the commission? For your reference, let’s take an example of an Acorn. Users are required to pay up to $1 per month to use their facilities. Besides that, it also lets users gain any commission in the trade by referrals and pockets.

    Do you also need to have such schemes in your business model? Think about it and prepare a business model as required.

  3. Initiate

    It’s time to start working on Robo advisor and the trading app mapping. There are stockbrokers and financial advisors in the offline world who help people invest their money. But, how in the online world does the same thing work?

    There are Robo advisors that can manage the money and are connected to the servers. Inside the networks, some gateways are used to transfer business knowledge to the trading mechanism. This is where you develop drawings of the whole structure, to ensure that each aspect of the system functions successfully.

  4. Incorporate Features

    When you are developing the system, you need to make a list of all the features, like

    • Do you want to make sure no fraud activities take place using the stock-broker app? Get SSL certificates.
    • Want secure login and secure services? Add two-factor authentication.
    • Does your business have so many investment options? Allow users to choose any service they want.

    These are just examples, you can go on thinking of what you want to provide your users and can integrate features accordingly.

  5. Build and Test

    Now, you are completely ready to build the share trading app if you have plotted all the features and sketched the outline for the app with the help of investment app developers or a mobile app development company. Designers and developers will build an interactive UI (UX) design for an investment app like acorns and will ensure the results are best. Also, before you go live with it, it is wise to test the software. This makes it easier for you to uninstall the glitches from the stock market investing app if any, with the quality analysis team consisting of two to three quality analysts.

Do you also want to create an investment app like Robinhood?

However, if you need a detailed guide for the feature incorporation, here is the list.

Must-Have Features in Your Investment App

Investment App Features

  1. Login & Personal Accounts

    A complete financial app like Acorns that is user-oriented and conversion-driven must need to have the login feature. Also, when you log in and if you don’t have an option to create your profile, what’s the meaning?

    For buyers, a personal profile with simple and advanced features is a must. Just like the acorns app, it can act as a private office where they can build a portfolio, track existing investments, and view the business situation. In order to not scare off the investor, make the signup process light and simple. You can also provide social profile registration to build accounts instantly.

  2. Money Management Tools

    If you plan to start an investing platform, money management tools have a special spot on the feature list you need to create.

    Why? People often seek the right way to handle their funds. So offer powerful dashboards to your target audience with instruments for currency, savings, and credit management. To take advantage of infographics, pie charts, interactive bars, etc. all the content should be visually appealing and insightful. Provide daily, weekly, and monthly reports to give a consistent image of their financial and investing operation to the customers. It is an excellent way to increase customer loyalty.

  3. Security and Privacy Protection

    Enhanced protection is the golden law for a financial institution to obey.

    The appearance of more advanced ways of financial crime is motivated by ever-developing technologies. Take personal information security seriously as users need to be sure that their information will not be hacked when engaging with your website. For example,

    • Develop a powerful IDPS (Intrusion Detection and Protection System) to take preventive steps to deter DDoS attacks.
    • Have encryption algorithms to ensure online payment security.
    • Safeguard the stock exchange app or website like Acorns from phishing methods.
    • Establish a staggered sign-up process and two-factor authentication to safeguard the funds and confidential data of investors.

    Also, make sure that your clients are aware of your security and data protection policy.

  4. Product Comparison

    Tools for comparing investing opportunities are another vital thing among the tips for features of an investment platform. Because investors are very selective when choosing a basket to place some of their eggs in.

    It reminds you, somehow, of shopping. You can’t take back your money if you don’t like a product. That’s why it’s so important to let customers see the difference, quantify benefits, and estimate risks between investment goals.

    Therefore, creating a special segment with many choices where users can set criteria and compare available options could be the simplest approach.

  5. Real-Time Alerts

    Don’t hesitate to introduce push notifications, personalized reminders, and real-time feedback as you start creating an investing framework.

    It keeps your clients up to date with their returns, tells them about suspicious events, and offers exclusive sales and discounts. To prevent obtrusiveness, encourage users to configure their notification settings.

  6. Client Support

    Last but not least on the list is client support. The optimistic change from a customer-centered approach to a business-oriented approach helps consumers to experience more commitment and concern. Earlier, firms couldn’t demonstrate the innovative idea of helping customers when call centers were used by all. But now, there are various easier means of standing out in the real estate market.

    For example, virtual assistants are becoming popular. You can develop a chatbot that will deal with traditional requests to reduce costs and improve user experience & interaction.

What are the APIs to Develop an Investment Mobile App?

The Cost to Develop a Mobile Investment App

There are no ideal app cost calculators, but you can always calculate it by using a basic formula (refer to it as an app cost calculator), which is as follows,

Total App Development Cost = Development Time x Cost Per Hour

However, the hourly rate of developers may be approx $50 and it can be varying from location to location. For more, look at the below table for hours breakdown depending on the features.

Project Management Approach For Investment App Development

There are so many agile approaches for developing a mobile application from a scrum to lean to extreme programming, that choosing one and the right approach is quite difficult.

However, under the broader body of agile techniques, ‘Scrum’ is a well-known iterative app development strategy. The key stakeholders of the project backlog and agile software development by Scrum are the product owner, scrum master, and scrum team. The PM serves as a ‘Scrum master’ while a ‘Product owner’ (PO) in a document called the ‘Product backlog’ offers the specifications or criteria.

The scrum team calculates the attributes, and sprints are to be planned by the scrum master. The development team will build a minimum viable product at first and then will develop in more sprints. The scrum squad holds a ‘Regular stand-up meeting’ during the project implementation. This session is meant to resolve the state of the initiative, and the scrum master uses it for dispute solving.

For a detailed understanding of your particular iOS or Android app development approach, you can find a software development company and ask for their suggestions.
