In-Depth Reviews
1. Acorns
Editor's Pick Best for Hands-Off BeginnersAcorns invented the "round-ups" investing concept — every time you make a purchase, it rounds up to the nearest dollar and invests the difference. Spend $3.75 on a coffee? Acorns invests $0.25 automatically. Over time, those pennies add up.
The app invests in pre-built ETF portfolios (from conservative to aggressive) curated by Nobel Prize-winning economist Harry Markowitz. You choose your risk level, and Acorns does the rest. It's not a tool for active traders — it's for people who want to invest without thinking about it.
✅ Pros
- Truly automatic investing
- No financial knowledge required
- Includes IRA retirement accounts
- "Found Money" cashback rewards
- Clean, easy-to-use app
❌ Cons
- $3/month fee eats into small balances
- Limited control over investments
- Not ideal for larger portfolios
2. Fidelity
Best Free Best Free Option for BeginnersFidelity is the gold standard for beginner investors who want to do things themselves. There are zero commissions on US stocks, ETFs, and options. You can open an account with $0 and start buying fractional shares of companies like Apple or Amazon for as little as $1.
Fidelity also offers its own line of index funds with a 0% expense ratio — literally free to own. The app and website are more feature-rich than competitors, and Fidelity's customer service is among the best in the industry. For long-term, buy-and-hold investors building wealth through index funds, this is hard to beat.
✅ Pros
- $0 commissions and $0 account minimum
- Fractional shares available
- 0% expense ratio index funds
- Excellent research and customer support
- FDIC/SIPC insured
❌ Cons
- Interface can feel overwhelming at first
- No automatic round-up investing
- Less slick than mobile-first apps
3. Robinhood
Best for Simple Mobile TradingRobinhood popularized commission-free trading and still delivers one of the cleanest, most intuitive mobile experiences available. You can buy stocks, ETFs, options, and crypto all in one app — no paperwork, no minimums, no confusing menus.
The app has matured considerably since its early days. Robinhood Gold ($5/month) adds a 5% APY on uninvested cash, margin investing, and premium research. For beginners who want to dip their toes into individual stocks with a small amount of money and a straightforward interface, Robinhood is still one of the easiest ways to get started.
✅ Pros
- Extremely clean and simple interface
- Fractional shares from $1
- Commission-free stocks/ETFs/crypto
- Robinhood Gold: 5% APY on cash
- IRA with 3% match (Gold subscribers)
❌ Cons
- Limited research tools vs. Fidelity
- Controversial PFOF payment practices
- Customer support can be slow
- Gold needed for best features
4. SoFi Invest
Best for Banking + Investing in One PlaceSoFi is a full financial platform — banking, loans, credit cards, and investing all under one roof. SoFi Invest offers both self-directed trading (you pick) and automated investing (they manage) with $0 fees on either. That's a rare combination.
For beginners who want simplicity, SoFi's automated investing is compelling: answer a few questions, and they build you a diversified ETF portfolio. You can also buy fractional shares of individual stocks. The real appeal is consolidation — if you already use SoFi for banking, adding investing is seamless and keeps your financial life in one place.
✅ Pros
- $0 commissions and $0 management fees
- Automated + self-directed in one app
- Fractional shares from $1
- Easy to use for beginners
- Integrates with SoFi banking
❌ Cons
- Fewer ETF options than Fidelity
- Automated portfolios less customizable
- Newer platform with less track record
5. Public
Best for Social/Community InvestingPublic is a commission-free investing app with a social twist — you can see what other investors are buying, follow creators, and discuss investments in a community feed. For visual learners and people who like to learn by watching others, it's surprisingly educational.
Public also offers Treasury accounts (high-yield bonds), alternatives investing, and crypto. The fee structure is tip-based for stocks, but there are paid tiers for more advanced features. It's not the most powerful platform, but for beginners who want to learn while investing, the social element genuinely helps.
✅ Pros
- Unique social/community features
- Commission-free stocks and ETFs
- Treasury and alternative investments
- Educational content built in
❌ Cons
- Tip-based model can add costs
- Fewer account types than competitors
- Less suitable for advanced investors
How to Choose the Right Investment App
Before you pick an app, figure out what kind of investor you want to be. If the idea of making financial decisions stresses you out, a hands-off app like Acorns or SoFi's automated investing is the right starting point. You answer a few questions about your goals and timeline, and the app handles everything else. If you're genuinely curious about the market and want to learn by doing, a self-directed platform like Fidelity or Robinhood will teach you far more over time.
Pay close attention to fees relative to your balance. A $3 monthly fee sounds trivial — but on a $100 balance, that's 36% of your money gone to fees annually. That math only improves as your balance grows. For very small starting amounts, a $0-fee platform like Fidelity or Robinhood is almost always smarter than paying a flat monthly subscription. The subscription model makes more sense once your portfolio is large enough that the fee is less than 0.5% annually — roughly $600+ for a $3/month fee.
Finally, think about which account type you need. A standard taxable brokerage account is the most flexible — you can withdraw anytime, no restrictions. A Roth IRA lets your investments grow tax-free, which is enormously powerful over decades, but you're limited to $7,000/year in contributions (2026 limit) and there are income rules. If you're under 40 and have earned income, opening a Roth IRA is one of the smartest moves you can make. Most apps on this list support both account types, so you're not locked in.
Amazon Book Recommendations for New Investors
The right book can shortcut years of trial and error. These three are worth every penny — and they'll give you more usable knowledge than most online courses.
The Little Book of Common Sense Investing — John Bogle
The bible of index fund investing. Bogle, the founder of Vanguard, makes an airtight case for why low-cost index funds beat almost every other strategy over time. Short, direct, and backed by decades of data. If you read only one investing book, make it this one.
I Will Teach You to Be Rich — Ramit Sethi
A no-BS, 6-week action plan for managing money in your 20s and 30s. Covers automating investments, credit cards, savings, and more with Sethi's signature candor. Less about theory, more about doing. It's the personal finance book people actually finish.
The Psychology of Money — Morgan Housel
Less about tactics, more about mindset. Housel explains why behavior — not knowledge — is the biggest factor in financial success. Easy to read, genuinely insightful, and full of stories that stick. A must-read for any investor at any experience level.
