Smartphone technology and zero-commission trading have changed how Americans invest. About 58% of adults now own stocks, up from 32% in 2010. This shift happened largely because apps made investing simpler and cheaper.
Old brokerages required big minimum deposits, charged high fees per trade, and used confusing interfaces. Modern apps dropped most of those barriers. You can open an account with $1, buy fractions of expensive stocks, and trade for free.
This guide looks at the top investment apps in 2025. We’ll cover what each offers, what they cost, and who they’re best for.
Why Investment Apps Changed Everything
The combination of smartphones and commission-free trading fundamentally altered personal finance. Apps put the stock market in your pocket. You can save for retirement, build an emergency fund, or grow wealth over time—without a financial advisor or tens of thousands of dollars to start.
“We are seeing first-time investors in their twenties engage with markets at rates never before possible,” says Sarah Chen, a financial technology analyst.
These platforms introduced features like rounding up purchases, dividend reinvestment, and built-in education. The ability to start with just $1 through fractional shares appeals to younger people who want to build wealth gradually.
What to Look for in an Investment App
Before choosing an app, consider these factors:
Fees: Many apps advertise zero commissions, but check for expense ratios on funds, withdrawal fees, inactivity fees, and premium feature costs. Small annual fees add up over decades.
Security: Reputable apps are regulated by the SEC and protected by SIPC (up to $500,000 if the brokerage fails). Look for two-factor authentication and encryption.
Account types: Some apps offer only stocks and ETFs. Others include mutual funds, bonds, options, and crypto. Decide whether you need a taxable brokerage, IRA, or both.
Education: Beginners benefit from clear explanations, simulated trading, and beginner-friendly content. Experienced investors may want advanced charting and research tools.
Support: How quickly can you get help when something goes wrong? Check response times and available channels.
Our Top Picks
After testing dozens of platforms, these apps stood out:
Fidelity Investments – Best Overall
Fidelity manages over $11 trillion in assets and offers zero-commission trading on stocks, ETFs, mutual funds, bonds, options, and fractional shares. There’s no minimum deposit to start.
The mobile app works well for basic trades, but Fidelity really shines for long-term planning. Its retirement tools, tax-advantaged accounts, and research resources are excellent. You also get access to professional-grade analysis if you want it.
What makes Fidelity stand out: no account minimum, strong education for beginners, and solid tools for advanced investors too.
Robinhood – Best for Beginners
Robinhood made its name by stripping away complexity. The interface is clean and minimal—perfect if you’ve never traded before. You see your balance, your holdings, and market movements without clutter.
The app offers commission-free trading on stocks, ETFs, options, and crypto. No minimum balance. No withdrawal fees. Fractional shares let you buy small pieces of expensive stocks like Amazon or Google.
Robinhood’s education section (Robinhood Learn) explains basics in plain language. But the research tools are thinner than competitors’, and Robinhood makes money from payment for order flow—something to be aware of.
Good choice if you want the simplest possible way to start buying stocks.
Charles Schwab – Best for Research
Schwab excels at giving investors information. You get independent third-party research, solid screening tools, and detailed analysis of thousands of securities.
The mobile app and website both work well. No commissions on stocks and ETFs. No account minimum. Schwab also keeps physical branch locations—a rarity these days—if you prefer in-person help.
Their mutual fund selection is strong, with thousands of no-transaction-fee options. If you want to dig into research before buying, Schwab delivers.
Vanguard – Best for Long-Term Investing
Vanguard invented the index fund. Founded by John Bogle, the company still offers some of the lowest expense ratios in the industry. If you want to buy index funds and hold them for decades, Vanguard is hard to beat.
The platform works well for IRAs and 401(k) rollovers. Target-date funds automatically adjust your allocation as you near retirement—a hands-off approach that appeals to many people.
The interface isn’t flashy. Vanguard prioritizes function over form. But for low costs and a philosophy centered on long-term passive investing, it’s excellent.
E*TRADE – Best for Advanced Trading
E*TRADE offers sophisticated tools for investors who want more control. Advanced charting, technical indicators, complex order types, and solid options trading capabilities.
Power ETRADE provides professional-grade features in a mobile app. The basic ETRADE app works fine for simpler trades. Zero commissions, zero account minimums.
Choose E*TRADE if you’re past the basics and want to execute specific strategies.
TD Ameritrade – Best for Education
TD Ameritrade shines if you want to learn. Their education center includes webinars, video courses, in-person workshops, and articles covering everything from stock basics to advanced options.
The thinkorswim platform offers paper trading—practice with simulated money before risking real cash. This feature alone makes TD Ameritrade worth considering for serious beginners.
Zero commissions, zero account minimum. The education resources are free with your account.
How to Get Started
Before downloading an app, build an emergency fund with three to six months of expenses. You don’t want to sell investments during a downturn because something unexpected came up.
Determine how much you can invest regularly. Set up automatic contributions if possible—dollar-cost averaging works well over time.
Most experts recommend starting with a diversified low-cost index fund or ETF. This gives you broad market exposure without betting on individual stocks. As you learn more, you can branch out.
Market swings are normal. Don’t try to time the market—it’s nearly impossible. Consistent contributions and patience beat trying to predict what happens next.
Conclusion
Investment apps made it easier to start building wealth. You can begin with $1, trade for free, and access the markets from your phone. Whether you prefer Fidelity’s all-around features, Robinhood’s simplicity, or Vanguard’s focus on long-term index investing, the hardest part is starting.
Pick the app that matches your experience level and goals. Then start investing. Consistency matters more than picking the perfect stock.
Frequently Asked Questions

Robinhood and Fidelity both require no minimum balance. Robinhood is simpler; Fidelity has more educational resources.
Are investment apps safe?
Reputable apps are SEC-regulated and SIPC-protected (up to $500,000 if the brokerage fails). Look for two-factor authentication and encryption.
Can I start investing with $100 or less?
Yes. Most apps have no minimum deposit. Fractional shares let you buy portions of expensive stocks with small amounts.
Do investment apps have hidden fees?
Check the full fee schedule. While trading is often free, you may find expense ratios, inactivity fees, or costs for premium features. Fidelity, Schwab, and Vanguard are known for transparency.
Should I use a taxable account or an IRA first?
For retirement, IRAs and 401(k)s offer tax advantages. If your employer matches 401(k) contributions, contribute enough to get the full match first. Roth IRAs work well for younger investors in lower tax brackets. Use taxable accounts for goals before retirement or after maxing out IRA contributions.
