Stash vs Robinhood vs Acorns – Which is the Best Micro Investing App?

Robinhood v Acorns v Stash computer comparison image


Have you been pondering investing and have not put aside a dime yet?

Let me guess – you have no money, and you know very little, if anything, about the workings of the stock market.

You are not alone. According to recent studies, close to half of all Americans don’t invest in the stock market and a quarter of all American adults have nothing saved for retirement, according to a recent Forbe’s articles. Not having enough money to invest and lack of understanding of the stock market are the most frequently cited reasons for that.

I understand; there is no way you could just drop over $2,000 on a share in Amazon, right?

What if I told you that you do not need so much money to start investing?

What if I told you that you could invest from as little as few dollars and get educated about stocks and shares in the process?

Enter micro-investing. Using micro-investing, you no longer need to buy one share in Amazon; you can buy as large or as small fraction of stock as you can afford.

Micro investing platforms and apps have largely democratized investing by allowing you to invest small amounts regularly and buying fractions of shares.

Not surprisingly, there has been a proliferation of micro-investing apps. Here we offer an overview of the main features and investing benefits of three such micro-investing apps. (Click on the links if you’re ready to visit the micro-investing apps’ websites):

We also compare Stash vs Robinhood vs Acorns to help you decide which of these is the best micro-investing app for you.

Robinhood Overview

Robinhood is a commission-free micro-investing platform offering access to US stocks and ETFs traded on the NYSE and Nasdaq. While Robinhood does not appear to take from the rich to feed the poor, this commission-free micro-investing app has set out to empower the investing underdog, e.g., people who have little money to invest.

Like other micro-investing apps, Robinhood offers fractional share trading. What sets Robinhood apart are two important innovations:

  • First, Robinhood pioneered fee-free trading, which has been emulated by brokerages like Fidelity, Charles Schwab, and TD Ameritrade.
  • Second, Robinhood introduced instant deposits of up to $1,000. It means that your deposits show in your Robinhood account, and are accessible, immediately, not three days after the transfer.

In some circles, Robinhood is viewed as the catalyst for the ongoing transformation of the investing landscape.

Robinhood is also the only one of the three micro-investing platforms reviewed here to have gone international – it has a UK broker license and is expected to start operating shortly.

Acorns Overview

Have you ever tried saving by emptying your change in a jar at the end of the day?

I have. And let me tell you that it adds up quickly and you don’t miss it.

It is the psychological trick Acorns, a versatile micro-investing app, uses to enable you to spend smarter, save regularly, and invest for the future.

Using Acorns is straight forward and simple – you connect the micro-investing app to your debit and credit cards and start automatically saving the difference to the nearest dollar every time you shop. (You can also make a one-off transfer or regular contributions.)

In Acorns speak, this is known as Round-Ups. Your Round-Ups are invested in a portfolio tailored to your situation and appetite for risk.

More recently, Acorns added its checking account and debit card to its array of offerings. This account saves, earns, and invest for you.

Acorns really may be a vehicle to build your big future using your small change. It is also great for beginner investors happy to forego investing choice for portfolios leaning towards the conservative.

Stash Overview

Stash is a ‘do it all home for your money’ helping you to achieve your financial goals by sound money habits, using technology, and investing education. It was designed to make money management and investing simple, straight forward, and a matter of habit.

The app offers online banking as well as micro-investing options. If you have not been investing because you have no money to spare, using Stash, you can start with $5; it does not sound that much at all, does it?

Stash is an appropriate banking and investing choice for people who have little money, limited knowledge about investing, and are willing to learn. It offers fractional share investing, manual, or automated by using Auto-Stash, investment selection, and quality money education.

It’s no surprize that 86% of Stash users are first-time investors. Stash appears to be positioning itself as a ‘nursery school for investors’ and taking pride in it.

Core Characteristics

Acorns: Core Characteristics

Acorns Investment Review - Acorns Fees + Features


Acorns: Account Minimum

There is no account minimum requirement to open an Acorns account. However, to start investing, you need to have a minimum of $5 in your account. (Your Round-Ups are saved in a holding account till your savings reach $5.)

Acorns: Investment Options

Acorns offer five ETFs pre-set portfolios that, reputedly, were designed with help from Harry Markowitz, winner of the Nobel Memorial Prize in Economic Sciences. These are:

  • Conservative portfolio comprised entirely of bonds.
  • Moderately conservative portfolio consisting of 40% stocks and 60% bonds.
  • Moderate portfolio that includes 60% stocks and 40% bonds.
  • Moderately aggressive portfolio with 80% stocks and 20% bonds.
  • Aggressive portfolio built entirely of stocks.

The platform is designed to suggest a portfolio for you based on your answers to a few simple questions.

There is no option to invest in individual stocks, bonds, mutual and index funds, or other investment vehicles.

Acorns: Fees

Acorns offer commission-free trades, and there are no minimum account fees either, just like Robinhood. Acorns are different in that they charge a monthly subscription fee of between $1, $2 or $3 depending on the type of account you open (until your investments reach $1 million).

Acorns: Types of Accounts

Acorns offer three different plans with several types of accounts.

Here is, at a glance, what Acorns offers:

Acorns Accounts and Plans

Acorns Invest
(Round-Ups, Bonus investments from partners, access to information)
Acorns Later
(Acorns Invest and a retirement account)
Acorns Spend
(Acorns Invest, Acorns Later and a checking account and debit card with no fees)

Acorns: Customer Care

Acorns offer good customer service for an online platform. There is ‘Acorns support’ where you can find information, and instruction, for every stage of the process – from signing up through the different accounts, to frequently asked questions.

In case this is insufficient, Acorns offer an email customer service.

There is also a customer service telephone number, but it is hidden under ‘Gift cards’ and at the end of this section at that. It is much easier to get the telephone number by a Google search. Lines are open Monday to Friday between 9:00 and 5:00.

Acorns: Educational Resources

Acorns offer access to articles on personal finance written by experts in the field under their ‘Grow’ section. While personal finance education is considered an important part of planting the acorns of your future money oak, it is not as central to the philosophy of Acorns as it is for Stash.

Acorns: Noteworthy features

It is worth noting the following features of Acorns:

  • Round-Ups. It is undoubtedly a great trick to encourage people who are not ‘natural’ savers to spend wisely and put away there change.
  • Customized portfolios. There is no messing about, and no attempt to please everybody – Acorns offer only customized portfolios to their customers, clearly targeting micro investors who know little about the stock market and are not that keen to learn.

Acorns Pros and Cons

Here is what we love about Acorns:

  • Acorns round ups go directly into an inestment account-making investing automatic
  • Offers retirement accounts
  • Offers a checking account and debit card.
  • “Found money” partners add mney to your account

Here are the features on which we are not too keen:

  • Subscription fee that is small but can have a large effect on micro-investing
  • Limited investing options

Acorns in a nutshell:

‘We help you plant the acorns of your wealth oak.’

Robinhood: Core Characteristics

robinhood app

Robinhood: Account Minimum

There is no minimum amount required to open an account with Robinhood, and there is no minimum balance fee.

In practice, you need a dollar to get into the stock market. Even better, using the fractional share investing options, you can invest in the ‘big ones’ like Apple, Amazon, and Google, even if you have only a few bucks to spare.

Robinhood also offers margin trading, and for that, you need a minimum of $2,000. It is quite a different ball game, however.

Robinhood: Investment Options

Robinhood offers stock trading, ETFs, cryptocurrency, and options trading.

One unique feature of Robinhood, a characteristic attracting much positive feedback, is that they also offer cryptocurrency trading. The cryptocurrency trading service allows you to buy and sell all major cryptos, including Bitcoin, Ethereum, and Litecoin.

Robinhood does not provide access to mutual funds.

Robinhood: Fees

Robinhood offers commission-free US stock trades. (Regulatory fees still apply, but this is life.)

There are a couple of hidden fees worth mentioning. There is a $50 fee to trade foreign stock and a $75 fee to transfer your account to a competing broker. There is also a $5 charge for issuing paper statements.

Overall, however, Robinhood’s fee structure benefits the user – no account fee, no commissions, and no minimum amount fee.

Robinhood: Types of Accounts

Robinhood offers two types of taxable investment accounts:

  • Their basic account is free and provides access to all investment options, free trading, and access to business news, performance summaries, and watch lists. This account offers the possibility to set limit orders, which is rather good for a free account.
  • There is also the Gold account to which you could upgrade for $5 per month. It will allow you an instant transfer of up to $50,000, access to margin trading, and market analytics.

Robinhood: Customer Care

Customer care is not among Robinhood’s strong points. It is entirely online, and there is no telephone service or a chatbot.

Robinhood has been experiencing some problems lately. For instance, in July 2019, they admitted to a security breach where customer passwords were compromised. In November 2019, a bug in the system allowed customers to use unlimited leverage, and on 2 March 2020, the day of the most significant daily point gain in the Dow Jones’s history, Robinhood had an all-day outage thus affecting investor returns.

Robinhood: Educational Resources

There is the basic information that covers the fundamentals of investing in the Robinhood app, but education is not an explicit focus of the platform.

Robinhood: Noteworthy Features

Three Robinhood features impress:

  • No-fee trading of US stock and free basic account. There is a flip side to this, e.g., Robinhood makes a substantial proportion of its money from payments for order flow.
  • Crypto trading. Robinhood, uniquely, allows micro investors to trade the leading cryptocurrencies.
  • International presence. Robinhood is expected to start operating in the UK anytime now.

Robinhood Pros and Cons

Here is what we love about Robinhood:

  • Commission-free investing
  • Variety of stocks and ETFs
  • Crypto trading

Here are the features on which we are not too keen:

  • Customer service
  • Outages because of coding bugs
  • Payment for order flow as a significant source of revenue

Robinhood in a nutshell:

‘We empower the ‘investing’ underdog.’

Stash: Core Characteristics

Here is what Stash has to offer the micro investor.

stash mobile

Stash: Account Minimum

There is no minimum amount, but, in effect, you need $0.01 for most stocks while those priced over $1k require $0.05 minimum. Stash buys shares in the stocks and ETFs made available on the platform and splits these for the investors.

It is how instead of buying an Amazon share for $2,000, you can purchase one-thousandth of it for $2 – you still end up owning some of the stock. You can also build from there.

Stash: Investment Options

Stash offers opportunities to invest in stocks, bonds and ETFs.

Stash: Fees

Stash offers three pricing plans:

  • Beginner: this plan costs $1 per month and offers a personal investment account, bank account, and access to financial education resources.
  • Growth: this plan costs $3 per month and offers you a personal investment account, retirement investing, bank account, and access to educational resources.
  • Stash+: this plan costs $9 per month and offers you the full range of benefits. On top of the benefits included in Growth, this plan offers investing accounts for two kids, a metal card with 2xStock-Back and monthly market insights report.

Stash: Types of Accounts

Stash offers investors three types of accounts:

  • Investment account
  • Retirement account
  • Custodial account

Investment accounts come with fractional shares, offer access to more than 400 stocks and funds, and can be automated. The final selection of your investments is left to you, but a lot of guidance, knowledge, and information are available to help you make up your mind.

Retirement accounts, available with Growth and Stash+ plans, are like the investment accounts but, besides, offer tax benefits through Roth IRA and Traditional IRA. Help and guidance are available to help you select the best account for you and to maximize your tax savings.

Custodial accounts, available with Stash+, allows you to open investment accounts for your kids.

Stash: Customer Care

Stash customer support includes phone and email access Monday to Friday between 8:30 and 6:30 EST. Phone ; the customer support channels work on Saturdays and Sundays between 11:00 and 5:00 EST.

Stash: Educational Resources

Stash has quality educational resources on general personal finance, ongoing money management, and investing. The material is clear, easy to understand, and to the point.

Stash: Noteworthy Features

Here are the Stash features worth noting. These are also the features that give Stash an edge when compared to Robinhood and Acorn:

  • Education: Stash, in my mind, is a bit like a nursery for ‘grown-up’ investors. While it allows you to select your investment, it also provides an extensive and well-targeted resources repository teaching customers about money management and investing.
  • Emphasis on habit building: Through automation and learning, Stash enables healthy money management at investing habits building. Hence, Stash can be used by young adults to develop money habits and set on the way to financial health.
  • Portfolio Construction: Stash offers a lot of basic guidance on picking investments including how to choose investiments in line with your values.

Stash Pros and Cons

Here is what we love about Stash:

  • Educational resources
  • Emphasis on habit formation
  • Variety of accounts and investing options
  • Customer support
  • Combining manual and automated selection of stocks and ETFs

Here are the features on which we are not too keen:

  • Small fees still add up
  • Stash lacks a clear, targeted mission
  • Stash tries to offer everything to everybody
  • Stash doesn’t offer rebalancing like other robo-advisors

Stash in a nutshell:

‘We help you to help yourself.’

The Winner Is….

This is how Stash, Robinhood, and Acorns compare according to their core characteristics.

Our overall verdict is that the best micro-investing app among the three reviewed here is Acorns. It is our favorite because of its psychologically appealing approach to saving and investing, the ease of investing afforded by the customized portfolios, the retirement account offering, and the good customer service and security.

Acorns offers an ideal way to begin investing automaticaly with small amounts of money.

The second best is Robinhood because it offers fee-free accounts and trading, and access to crypto and options trading. Robinhood also has a strong message which permeates all their operations. Where Robinhood lose points to Acorns, and Stash, is their customer service, the questions around security and the platform outages that have recently been plaguing it.

A similar app to Robinhood is the free Webull Investing App.

Stash is in third place mainly because of its fee structure and lack of clear identity. Our impression is that Stash is trying to be everything to everybody, which makes it harder to position and impress.
