Best Investing Apps for iPhone

Fidelity is the best investing app for iPhone because it does what every other broker does, does it without PFOF on equities, supports every account type you'll ever need, and doesn't disappear features as your balance grows. The iOS app holds the deepest feature set of any broker on this list — full retirement suite (Traditional, Roth, SEP, SIMPLE, Solo 401k), 529 plans, custodial accounts, cash management with a 4%+ yield on uninvested cash, fractional shares from $1, and active-trading screens that don't embarrass next to thinkorswim. Fidelity differs from Robinhood by being designed to host every financial relationship — paycheck, savings, brokerage, retirement, college plan — rather than being a mobile-first trading app. A real scenario: you open a Roth IRA, set up a $200 monthly auto-deposit into a target-date fund, and 25 years later you still don't need to switch brokers. The tradeoff is the iOS app has more screens than a one-job app needs, and active traders may find order entry slower than Robinhood. No monthly fee. No account minimum.

Schwab Mobile is the best investing app for people consolidating bank and brokerage into one provider because Schwab Bank's worldwide ATM-fee reimbursement and the Schwab brokerage entity sit on a single login. Schwab also owns thinkorswim — so active traders can run Schwab Mobile for the standard workflow and thinkorswim for charting and options without leaving the ecosystem. Schwab differs from Fidelity by leaning toward private-bank polish: dedicated representatives kick in at higher balances, ATM reimbursements anywhere in the world on the checking account, and the broadest international-market access on iOS. A real scenario: you're rolling a $250K 401(k) from a previous employer; Schwab assigns a transition specialist, walks the paperwork through in a week, and you wake up the next month with the balance invested in a three-fund portfolio. The tradeoff is the iOS app feels slightly older than Fidelity's, and the dual-app structure with thinkorswim confuses users who didn't come from Ameritrade. No commissions on stocks, ETFs, and Schwab funds.

Robinhood is the best investing app for iPhone-first active traders because the order-entry flow is faster than any traditional broker, and the iOS interface is the cleanest in the category. It pioneered zero-commission trades, fractional shares, and the friction-free mobile-trading experience the rest of the industry copied. Robinhood differs from Fidelity by being mobile-first by design rather than mobile-as-a-companion. A real scenario: an earnings move hits at 9:32 AM, you open Robinhood, place a limit order in under 20 seconds with Face ID confirmation, and watch the fill come back in real time. The tradeoff is well-documented: Robinhood still receives payment-for-order-flow on options (it dropped PFOF on equities in 2024), which means trade routing optimizes for someone else's economics; the gamified UI nudges activity that isn't always in your interest; and customer support, while improved since 2020, still trails Fidelity. Gold subscribers get 4% on cash and a 1% IRA match — both real benefits if you carry balances.

Acorns is the best investing app for beginners who haven't started yet because it removes the only decision that actually stops people: 'how much should I invest?' Round-up investing takes the change from your daily debit purchases (round a $4.37 coffee to $5, invest the $0.63) and drops it into a diversified ETF portfolio automatically. Acorns differs from Fidelity by automating the investing decision entirely — you don't pick stocks, you don't pick ETFs, you pick a risk level and Acorns handles the rest. A real scenario: you spend $1,800/month on a debit card, round-ups average $45/month, recurring deposits add another $50, and a year later you have $1,300 invested without ever consciously transferring money. The tradeoff per recent reviewers is the flat $3/month fee, which is a punishing percentage on small balances — at $1,000 invested, $3/month is 3.6% annually. Above $5,000 the math gets reasonable. Acorns Later wraps IRAs into the same auto-invest flow. Best as an on-ramp, not a long-term home.

Yahoo Finance is the best investing app for iPhone users who want a serious research and watchlist layer alongside their broker app. It's not a brokerage — you can't place a trade — but it's the most-used independent finance app in the U.S. App Store at 4.75 stars across 618,180 U.S. ratings, with a feature set that covers real-time quotes, fundamentals, analyst estimates, earnings calendars, options chains, and a customizable portfolio overlay that can mirror your actual holdings. Yahoo Finance differs from every other pick by sitting outside the trade-execution side entirely. A real scenario: you keep Yahoo Finance open during earnings season to scan the calendar and read transcripts, then jump to Fidelity to act on what you read. The tradeoff is the free-tier ad density and the Premium tier ($349/year for Yahoo Finance Plus) gating advanced research, technical screeners, and ad-free browsing. Best as a research companion, never as a substitute for an actual broker app.

SoFi is the best investing app for people who already use SoFi for banking, lending, or refinancing because the brokerage layer integrates tightly with the rest of the SoFi stack — one login covers checking, savings, loans, credit card, and investing. SoFi differs from Fidelity by being a personal-finance super-app rather than a dedicated broker. A real scenario: your paycheck lands in SoFi checking, $200 auto-routes to a Roth IRA in SoFi Invest, $100 routes to a high-yield savings vault, and you see all of it on one balance sheet. The tradeoff is SoFi's brokerage is the youngest among full-service picks here — fewer order types, no Level-2 quotes, weaker tax-lot management, and a thinner research layer than Fidelity or Schwab. SoFi reintroduced crypto trading via Galaxy Digital in late 2024, so the offering depends on what's live at sign-up. Best for users whose financial life is already centered on SoFi and who want investing as the next module, not as the primary product.

thinkorswim is the best investing app for iPhone-first active traders who want desktop-grade charting, options analytics, and risk tools on a phone. Now run by Charles Schwab, thinkorswim Mobile inherited the platform's professional toolset — Level-2 quotes, multi-leg options strategy builders, advanced order types, and the same scanners traders use on the desktop client. thinkorswim differs from Schwab Mobile by leaning all-the-way into active trading; it's not a beginner's app. A real scenario: you build a multi-leg options strategy (a credit spread), use the strategy builder to see breakeven and max-loss in dollars, place the four-leg trade in one ticket from your phone, and monitor the position with custom alerts. The tradeoff is the dual-app structure with Schwab Mobile is confusing for users who only need the standard brokerage workflow, and the interface curve is steep — newcomers will spend a week getting comfortable. Same SIPC coverage and execution as Schwab. No commissions on stocks and ETFs; options at $0.65 per contract.

Webull is the best investing app for active traders who want advanced charting on iOS without paying for thinkorswim's complexity. Webull leads with technical charting, Level-2 quotes via a paid Nasdaq TotalView add-on, paper-trading simulation, and a community trading-ideas feed. Webull differs from Robinhood by leaning into chart-based decision-making rather than one-tap buy/sell, and from thinkorswim by being friendlier to a newer active trader. A real scenario: you set up a watchlist of 20 tickers with custom indicators (RSI, MACD, VWAP), get alerts when a chart pattern triggers, and execute a limit order in three taps from the chart screen. The tradeoff is Webull receives payment-for-order-flow on equities and options — the standard PFOF caveats apply — and crypto offerings have shifted multiple times in recent years, so verify what's available before relying on Webull for digital assets. Zero commissions on stocks, ETFs, and options. IRAs are supported. SIPC-insured through Apex Clearing.

MyMerrill is the best investing app for Bank of America customers who want their brokerage on the same login as their checking, credit card, and mortgage. At 125,813 U.S. ratings and a 4.74 average, MyMerrill carries a strong rating-volume score that reflects Bank of America's massive existing customer base rather than a feature win. MyMerrill differs from Fidelity by being tightly coupled to a parent bank: transfers between BofA accounts and Merrill brokerage are instant, the Preferred Rewards tier offers real perks (credit-card boosts, mortgage discounts) tied to combined balances, and the Merrill Edge brokerage offers self-directed and advisor-managed options under one roof. A real scenario: you have $25K in BofA checking and a $50K rollover IRA at Merrill; the Preferred Rewards Platinum tier kicks in, your credit-card cash back jumps 75%, and the linked-balance benefit alone pays for staying. The tradeoff is the iOS app feels more like a banking app with a brokerage tab than a brokerage-first experience, and trade execution is slower than Fidelity or Robinhood. Best for households already inside the Bank of America ecosystem.

Robinhood Banking is Robinhood's checking and savings layer launched in 2024 to bring Gold subscribers a fintech-style account alongside their brokerage. At 4.94 stars across 47,370 U.S. ratings, the early-cohort sentiment is exceptionally strong. Robinhood Banking differs from every other pick on this list by not being an investment account — it's a checking + savings product that pays a competitive APY on idle cash (around 4% as of recent disclosures, subject to change), with on-demand cash delivery in some U.S. cities for Gold members. A real scenario: your paycheck lands in Robinhood Banking, idle cash earns the Gold APY automatically, and you sweep $500 to your Robinhood brokerage to buy fractional shares without leaving the app. The tradeoff is two-fold: it requires Robinhood Gold ($5/month or $50/year) for the headline APY, and FDIC coverage is through partner banks, not Robinhood itself — confirm the pass-through structure before parking a large balance. Best as a Gold-subscriber companion to the standard Robinhood brokerage, not a standalone bank.
