What are investment apps?

In simple terms, Investment Apps are trading platforms that are available on a mobile device. They offer a variety of services such as access to financial markets, it lets you buy and sell a plethora of financial assets such as stocks, ETFs, and options. 

Previously, you’d have to have a stockbroker make trades on your behalf however, investment apps negate the need for a stock broker. 

With an investment app, you can easily trade and invest from anywhere in the world, provided you have an internet connection. 

Generally, investment apps are affiliated with discount brokers and the app is part of their brokerage platforms. 

It is also important to note that the features and tools available on the investment app will vary depending on the discount broker they are affiliated with. 

Picking the Best Investment Apps

When picking an app for investing, you should follow the following criteria.

Regulation

The broker that you decide on should be regulated by a tier-1 financial institutions such as the Financial Conduct Authority (FCA), ASIC, MAS, and others. Choosing a broker that is regulated protects you and your financial assets against potential fraud. It offers clients a sense of security. But, we would advise that you research the financial institution as well, to ensure that they are reputable and trusted. 

Fees & Commissions

Generally, the fee structure is easily found on the broker website. Checking the fee structure is a great way to familiarise yourself with the broker and avoid those pesky hidden fees. 

Device Compatibility

Most investment apps support iOS and Android. Keep in mind that the iOS and Android versions also play a role in whether or not the investment app will work. This is something you should check. 

Research and Trading Tools

Research and trading tools are essential for developing a trading strategy and deciding on which financial assets to pursue. As a general rule of thumb, the investment app that you choose should offer a robust selection of research and trading tools. It is also beneficial if they offer great research content as well. Tools you should look out for are live data and news feeds, historical data, and charting tools. 

Education

Ensuring that the investment app you chose has robust educational content and tools is essential, especially if you’re a beginner. Educational tools and content can aid you in learning about trading and financial assets. It is a great way of familiarizing yourself with the financial markets and how assets operate. Educational tools and content include paper trading accounts, webinars, and tutorials. 

What are your goals?

This is one of the most important questions that you need to consider before choosing an investment app. If your goal is a long-term investment, you would want to invest in assets like stocks and shares. If your goal is a short-term investment, you might want to look at dividend stocks or even ETFs. Your goals can act as a guide on what you might need from your investment app. It can also help you narrow down your options.

What can you invest in?

You should ensure that the investment app you choose offers the financial assets that you’d like to invest in and trade. If you want to invest in a specific asset, it would be wise to choose an investment app that offers some benefits for that asset. If you want a more diverse portfolio, we would advise that you choose an investment app that offers a wide range of assets to invest in. 

Do you want to trade or invest?

It is important to be aware of the distinction between investing and trading. While both are methods of making a profit in the financial market, they operate differently. Investments are a long-term means of engaging with markets and generally apply to retirement accounts or college funds. Trading is a short-term means of engaging in financial markets and aims to maximize returns at a daily, monthly, or quarterly rate. Depending on your goals, you might choose either investments or trading. You might even decide to partake in both. 

How to open an account?

  1. Once you’ve done your research and have chosen an investment app, it is time to begin the application process. 
  2. The application process will depend on the broker and investment app that you choose. It can also depend on the type of account you choose. 
  3. Generally, when applying, you need some basic information about yourself. These include your identification or social security number, your date of birth, and your address. You might also need to answer some basic questions about your employment.
  4. Most investment app applications take place online but if you don’t feel comfortable with this method, some brokers do offer physical applications that you can print out. 
  5. Once you’ve applied, your account and personal information need to be verified by the broker. How long this process takes will vary from broker to broker.

FAQ

Which investments have the best returns?

There are a few high-return investments that we can discuss here. However, if you’re a beginner, we would recommend you start with a simpler, lower-return investment. This is because high return investments are closely linked to high risks. 

Jumping into high-return investments without having the know-how can put your financial health at risk. If you’re a seasoned investor, this shouldn’t be an issue. 

Here are a few high return investments that you can look into:

Forex investments: Forex investments involve buying and selling different currencies. Countries have their currencies and these currencies are valued with other currencies. 

Given the high risks of fraud, you should make sure to choose a reputable and regulated broker. Forex.com is a great option for this. 

High dividend stock: Dividends are a means of profit-sharing. It involves companies making regular payments to their shareholders. This gives investors a constant stream of income. 

But, we should note that companies are not required by law to pay dividends. Stock dividends are generally paid through a reinvestment plan or a cash option. 
Dividend stock can be high risk depending on the companies you choose to invest in. Companies with a long track record of low volatility and financial stability are better at dealing with market fluctuations than those without. 

How much do I need to start investing?

Investment apps and discount brokers sometimes require high account minimums to start trading. Some apps can also have high deposit requirements as well. 

Investment apps and brokers each have different fee structures and we recommend that you check these out before making a decision. Checking the fee structures can help you avoid those pesky hidden fees. 

If you’re a beginner and want to try out live stock broking without investing too much money, you could check out micro-investing apps like Stash and Acorn. These apps let investors start an investment portfolio with a relatively small amount of capital. 

Another issue that can affect how much you need to start investing in the asset type that you want to invest in. Stock shares can range in value from a couple of dollars to hundreds and thousands of dollars per share. Mutual funds generally have a minimum of $1,000 and more. 

Our advice, as always, is to do your research before committing to anything. 

Are Investment Apps safe?

Most investment apps form part of a larger brokerage platform owned by discount brokers. These brokers should be regulated by financial and government institutions such as banks or the FCA. 

Brokers should also be insured by institutions like SIPC and include investor protections. 

Most investment apps have numerous ways to keep you and your assets safe. Generally, investment apps have a two-step account login verification/authentication. Investors' personal information is also encrypted and there should be regular checks for hacking. 

If you’re a frequent traveler or have an active lifestyle, we would advise against using your investment app on public wifi networks such as offices, coffee shops, malls, and hotels. You can look into getting a VPN if you want an extra layer of protection.

Which is better – SoFi or Stash?

Stash and SoFi both offer fractional shares and they offer IRA accounts. They both offer prebuilt portfolios that users can invest in. 

Key differences are that SoFi offers to trade in cryptocurrency while Stash does not. 

Stash offers online banking as well as a cash management feature in addition to the general brokerage services. Stash also charges a monthly fee ranging from $1 to $9.

SoFi is free to use when trading stocks and ETFs. However, SoFi does not offer custodial accounts, while Stash does offer custodial accounts.

Which Is Better – Robinhood or stash?

Both investment apps don’t require a minimum investment to begin trading and offer taxable accounts and investment in ETFs. 

Robinhood and Stash are available on both Android and iOS and offer investment in individual stocks. 

A key difference between these apps is that Robinhood does not charge commission fees or account fees for their basic account, while Stash charges $1 per month for accounts under $5,000. 

If you’re aiming to invest in designated SRI (socially responsible investing) portfolios, you should consider Stash. 

If you’re interested in investing in cryptocurrencies or options trade, you should consider Robinhood.
