What it is

An investing app is a brokerage account you manage from your phone or browser. It lets you buy and sell stocks, ETFs, options, and often bonds, treasuries, and crypto, and it holds your positions and cash. The good ones add fractional shares, retirement accounts, research tools, and automatic investing. The category spans everything from bare-bones mobile-first apps to full-service brokerages with decades of infrastructure behind them.

Why it matters

Where you hold your money quietly decides how much of it you keep. A fund with a 0% expense ratio versus one at 0.5% is thousands of dollars over an investing lifetime, and the availability of a Roth IRA or a low margin rate shapes your real returns as much as any stock pick. Just as important, the app's design either encourages patient investing or pushes you toward the kind of frequent trading that quietly erodes gains. The right platform makes the boring, winning behavior the easy one.

Key features to look for

Fund costs and commissionsEssential

Zero-commission stock and ETF trades are standard, but expense ratios on funds and options contract fees are where costs actually live over time.

Account typesEssential

Access to taxable brokerage, traditional and Roth IRAs, and rollovers. Missing retirement accounts is a real limitation for long-term investors.

Research and screening tools

Quality analyst research, screeners, and data. The difference between guessing and making an informed decision, especially for individual stocks.

Range of assets

Stocks and ETFs are universal, but access to bonds, treasuries, options, and fractional shares widens what you can actually build a portfolio from.

App design and behaviorEssential

An interface that encourages steady investing rather than constant trading protects your returns more than most people realize.

Cash management and yield

Interest on uninvested cash and integrated high-yield options mean your idle money is not sitting at 0% while you decide what to buy.

Mistakes to avoid

×Chasing the flashiest trading interface over low fund costs. A slick options screen means nothing next to a 0% versus 0.5% expense ratio compounding for thirty years.

×Opening a taxable account when a Roth or traditional IRA fits your goal. Skipping the tax-advantaged account leaves real money on the table every single year.

×Letting the app's design pull you into frequent trading. Constant buying and selling almost always underperforms leaving a diversified portfolio alone.

Expert tips

→Prioritize the brokerage that offers the account type you need most, usually a Roth or traditional IRA, before you weigh anything else.

→Automate recurring investments into low-cost index funds so contributing becomes a default, not a monthly decision you might skip.

→Check where each app parks your uninvested cash. A high-yield sweep quietly adds returns while you decide what to buy.

The bottom line

For the vast majority of investors, Fidelity is the right home base: zero-fee funds, strong research, and every account type you need. Charles Schwab matches it and adds thinkorswim for active traders, while Interactive Brokers is the clear winner for global reach and low margin. Beginners should start with Robinhood for its simplicity, and Public is the standout if you want bonds and treasuries alongside stocks. Pick on account types and fund costs, since the commissions are already zero everywhere.

Frequently asked questions

Which investing app is best for beginners?

Robinhood is the easiest place to start, with a clean app and fractional shares. Fidelity is the better long-term home once you want retirement accounts and research, and both are free to trade stocks and ETFs.

Are these investing apps actually free?

Stock and ETF trades are commission-free across all five. Costs still hide in fund expense ratios, options contract fees, and margin interest, which is where you should compare rather than on trade commissions.

Is my money safe in an investing app?

Reputable US brokerages carry SIPC insurance covering up to $500,000 in securities if the firm fails, which is separate from market losses. Use strong credentials and two-factor authentication on any account holding real money.

Can I hold retirement accounts in these apps?

All five offer traditional and Roth IRAs. Robinhood adds a 3% match on contributions for Gold members, and Public adds a 1% match, so the account type is no longer the deciding factor between them. This comparison was last reviewed as of September 2026.
