Best Automatic Investing App: A Practical Guide for 2024

If you have ever wished you could invest without thinking about it, you are not alone. Automatic investing apps have made it possible to build wealth in the background — through round-ups, recurring deposits, and algorithm-managed portfolios. But with so many options, how do you find the best automatic investing app for your specific needs?

This guide breaks down how these apps work, what to compare, and which platforms are worth considering. Whether you are a first-time investor or someone looking to simplify an existing strategy, you will find practical advice to make an informed decision.

What Is an Automatic Investing App?

An automatic investing app is a mobile or web-based platform that lets you invest money on autopilot. Instead of manually placing trades every time you want to invest, you set rules and the app handles the rest. Common automation features include:

• Round-ups: Spare change from everyday purchases gets automatically invested.
• Recurring deposits: A fixed amount transfers from your bank account into investments on a schedule you choose.
• Automatic rebalancing: The app adjusts your portfolio to maintain your target asset allocation.
• Dividend reinvestment: Earnings are automatically used to buy more shares of the fund.

These tools remove the emotional side of investing and help you stay consistent — which research consistently shows is one of the biggest drivers of long-term returns.

How Automatic Investing Apps Work

Round-Up Investing

Apps like Acorns link to your debit or credit card. Every time you make a purchase, the app rounds the amount up to the nearest dollar and invests the difference. For example, a $4.50 coffee becomes a $5.00 charge, and the $0.50 goes into your investment portfolio. Over weeks and months, these small amounts accumulate into meaningful contributions.

Recurring Investments

This is the simplest form of automation. You set a dollar amount and a frequency — say, $100 every Friday — and the app buys shares of your chosen funds or stocks on that schedule. It is essentially a DIY dollar-cost averaging strategy executed automatically.

Robo-Advisor Portfolios

Platforms like Betterment and Wealthfront use algorithms to build and manage a diversified portfolio based on your risk tolerance, timeline, and goals. They handle rebalancing, tax-loss harvesting, and deposits automatically, giving you a hands-off experience similar to working with a human financial advisor — at a fraction of the cost.

7 Key Features to Compare Before Choosing

Top Automatic Investing Apps to Consider

1. Acorns

Acorns popularized the round-up model and remains one of the most recognizable names in automatic investing. It invests your spare change across a diversified portfolio of ETFs. It is ideal for beginners who want a truly hands-off experience and are comfortable starting with very small amounts.

Best for: Beginners who want to invest spare change with minimal effort.

Consideration: The monthly subscription fee ($3–$5) can represent a high percentage of a small balance.

2. Betterment

Betterment is a full-service robo-advisor that builds personalized ETF portfolios, handles automatic rebalancing, and offers tax-loss harvesting on higher-tier plans. It supports IRA and individual brokerage accounts and provides goal-based planning tools.

Best for: Investors who want a comprehensive, algorithm-managed portfolio with minimal involvement.

Consideration: You do not pick individual stocks — the platform manages everything.

3. Stash

Stash combines automatic investing with educational content and a stock-back rewards program. Users can start with as little as $1 and choose from themed portfolios or individual stocks. It also offers a debit card that earns stock-back rewards on purchases.

Best for: First-time investors who want guidance and a learning component alongside automation.

Consideration: Monthly fees apply, and some investment options carry higher expense ratios.

4. Wealthfront

Wealthfront is another leading robo-advisor known for its competitive fee structure and robust automation. It offers automatic rebalancing, tax-loss harvesting, and a high-yield cash account. The minimum to start is $500, and the management fee is relatively low at 0.25% annually.

Best for: Investors with moderate balances who want institutional-grade automation at a low cost.

Consideration: No option to invest in individual stocks.

5. Robinhood

Robinhood is primarily known for commission-free trading, but it also offers recurring investments — you can set and forget automatic purchases of stocks and ETFs with no fees. It gives you full control over your portfolio while still offering automation on your terms.

Best for: Investors who want automation without giving up control over individual investments.

Consideration: No robo-advice or automatic rebalancing; you manage your own allocation.

6. Public

Public combines social features with automated investing. You can set recurring investments in stocks and ETFs and access a community-driven platform with educational content. It also offers a high-yield savings account.

Best for: Investors who value community and education alongside automation.

Consideration: Relatively newer platform; fewer advanced portfolio management features.

7. M1 Finance

M1 Finance lets you create custom “pies” — portfolios divided into slices of stocks and ETFs — and automatically rebalances them when you deposit money. You can set up automatic deposits, and the app distributes them according to your target allocation.

Best for: Investors who want hands-on control over their portfolio with automated rebalancing.

Consideration: No tax-loss harvesting or retirement account options on the free tier.

Fees Breakdown: What You Actually Pay

Fees are one of the most important factors when choosing an automatic investing app. Even small differences compound significantly over time. Here is a general overview:

• Subscription-based apps (Acorns, Stash): Typically $1–$5 per month. This can be expensive relative to small balances.
• Robo-advisors (Betterment, Wealthfront): Usually 0.25% of assets under management annually. On a $10,000 balance, that is $25 per year.
• Commission-free trading platforms (Robinhood, Public): $0 per trade, but you are responsible for your own investment choices.
• Fund expense ratios: Most platforms invest in ETFs with expense ratios between 0.03% and 0.10%, which is quite low.

Tip: Always calculate the total cost — subscription fee plus expense ratios — before committing to a platform.

Pros and Cons of Automatic Investing

Pros

• Consistency: Automated contributions help you invest regularly regardless of market conditions.
• Emotion-free decisions: The app removes the temptation to time the market or panic-sell.
• Low barrier to entry: Many apps let you start with $1 or less.
• Time savings: Once set up, you can largely ignore your portfolio.
• Diversification: Robo-advisors automatically spread your money across asset classes.

Cons

• Limited control: Robo-advisors do not let you pick individual securities.
• Fees can add up: Subscription models may cost more than they are worth for small balances.
• No personalization: Algorithms follow broad rules and cannot account for your full financial picture.
• Over-reliance on automation: You may neglect to review your portfolio periodically.

How to Choose the Best App for Your Situation

There is no single best automatic investing app for everyone. The right choice depends on your goals, experience, and budget. Here is a simple decision framework:

1. If you are a complete beginner with limited funds: Consider Acorns or Stash for their low entry point and educational resources.
2. If you want a fully managed portfolio: Betterment or Wealthfront offer the most comprehensive robo-advisor experience.
3. If you want control with automation: Robinhood or M1 Finance give you the flexibility to choose investments while still automating contributions.
4. If you are investing for retirement: Look for apps that offer IRA accounts with automatic contributions and tax-advantaged growth.

Getting Started: A Step-by-Step Checklist

1. Define your financial goal (retirement, emergency fund, general investing).
2. Determine how much you can afford to invest automatically each month.
3. Compare at least three apps based on fees, features, and account types.
4. Read recent user reviews and check the app’s security credentials.
5. Start with the lowest-risk option and a small amount to test the platform.
6. Set up your recurring deposits and automation rules.
7. Review your portfolio quarterly to ensure it still aligns with your goals.

Common Mistakes to Avoid

• Ignoring fees: A $3 monthly fee on a $200 balance is 18% annually — that is enormous.
• Setting and forgetting completely: Automation is a tool, not a replacement for periodic review.
• Choosing based on marketing alone: Promotional offers do not reflect long-term value.
• Over-automating: Make sure you still have an emergency fund and are not investing money you might need soon.

Final Verdict

The best automatic investing app is the one that aligns with your financial situation, goals, and comfort level. If you want simplicity and spare-change investing, Acorns or Stash are solid starting points. If you prefer a professionally managed portfolio, Betterment and Wealthfront deliver excellent robo-advisor services at a reasonable cost. And if you want to maintain control while automating contributions, Robinhood and M1 Finance strike a strong balance.

Start small, compare fees carefully, and remember that consistency matters more than perfection. The best investing strategy is the one you actually stick with — and automatic investing apps are designed to help you do exactly that.
