thinkorswim

As of September 2026, the stock-trading apps I’d shortlist for most U.S. investors are:

Best overall picks

My practical recommendation

• If you want one safe default: choose Fidelity or Schwab.
• If you want the easiest app: choose Robinhood.
• If you trade actively or use options: choose Schwab thinkorswim, IBKR, or Power E*TRADE.
• If you like mobile charting and paper trading: choose Webull.
• If you already bank with Chase or Bank of America: consider J.P. Morgan Self-Directed Investing or Merrill Edge, mainly for convenience; StockBrokers.com ranked Merrill Edge highly among bank brokerages and described J.P. Morgan Self-Directed as a logical choice for Chase customers who value integration. (stockbrokers.com) |

Quick “don’t overthink it” ranking

1. Fidelity — best all-around for most people.
2. Schwab + thinkorswim — best if you want a major broker plus advanced tools.
3. Robinhood — best simple, fast mobile experience.
4. Interactive Brokers — best for advanced/global/serious traders.
5. E*TRADE / Power E*TRADE — best active-trader alternative.
6. Webull — best mobile charting-focused Robinhood alternative.
7. Merrill Edge or J.P. Morgan Self-Directed — best if your bank relationship matters more than trader features.

For most people, I’d start with Fidelity or Schwab, then add Robinhood/Webull/IBKR only if you specifically want a different trading experience. None of these apps makes trading low-risk—stock, options, margin, and crypto trading can lose money.

Best Stock Trading Apps

Based on current reviews and usage trends, here are the top stock trading apps people actually rely on, organized by what they're best for:

Best Overall

• Fidelity – Fidelity Investments is considered the best overall stock trading app thanks to its low fees, variety of order types, comprehensive research tools and intuitive interface. It's frequently cited alongside Schwab and Interactive Brokers as a top pick in 2026 rankings.
• Charles Schwab & Interactive Brokers – Independent testing by StockBrokers.com found that Charles Schwab, Interactive Brokers, and Fidelity lead the 2026 rankings, based on evaluations covering commissions, account minimums, account types, and investment selection alongside how each app performed during market hours.

Best for Beginners

• Robinhood – Robinhood is recognized as one of the best stock trading apps for beginners because of the platform's accessibility, driven by commission-free trading for stocks, ETFs and options, along with fractional share purchases that make it easy to get started for less. It also offers 24/7 support directly within the app for users who need extra help.
• eToro – Some reviewers rank this as the top overall app, noting eToro is the single best app to buy stocks for most users because it offers access to stocks, ETFs, cryptocurrency, and other assets regardless of where you live in the world, with a low minimum deposit: $50 USD (depending on your residency).

Best for Active/Day Traders

• thinkorswim (Charles Schwab) – thinkorswim is the best stock app for day traders, designed for active, day-trading stock pickers. It lets you chart with drawing tools, add volume and momentum indicators, check time and sales data, and execute orders from inside the app.

Best for Low-Cost Trading

• SoFi Invest – Noted specifically for low-cost trading among top overall picks.

Newer/Alternative Option

International Options (if outside the US)

• Trade Republic – A European favorite that charges €1 per order and applies no fees on scheduled investment plans, and no custody fees.
• Trading 212, XTB, Degiro, IG – Also commonly listed among Europe's top trading platforms.

Quick Recommendation

The "best" app really depends on your priorities — fees, asset variety (stocks/options/crypto), and whether you want a beginner-friendly interface or advanced charting tools for active trading.
