Investing apps: what to check before you choose one

Why the Right Investment App Matters More Than Ever

Over 10 million people in the United Kingdom now use investing apps, according to the Financial Conduct Authority's 2024 retail investment data. That figure has tripled since 2020. The entry barrier to investing has collapsed: no minimum deposits, no broker phone calls, no paper forms. Anyone with a smartphone can build a portfolio before breakfast.

This democratization carries risk. Between January 2022 and December 2023, nearly 40% of first-time app investors lost money in their first year, per Morningstar research. The problem wasn't market performance. The problem was choosing the wrong platform for their needs, paying excessive fees, or misunderstanding the protections—or lack thereof—attached to their investments.

The best investing apps align with your specific financial goals, risk tolerance, and investment knowledge. A beginner buying index funds needs different features than a day trader moving in and out of individual stocks. Someone building a pension requires different regulatory safeguards than someone experimenting with cryptocurrency. Before you transfer a single pound, you must understand what separates a solid investment platform from a costly mistake.

How Maclear compares with a bank savings account

If you are weighing an investing app against leaving money in the bank, here is how P2P loan claims on Maclear line up against a bank savings or deposit account.

Maclear figures accurate as of 2026. Not investment advice; capital is at risk, including possible total loss.

A P2P allocation is best treated as a portfolio addition (around 10%), not a replacement for lower-risk instruments.

How the investment works and what stands behind your money

• Each investment is an assigned claim to a vetted business loan: the borrower signs the loan agreement with the platform, and you hold the claim.
• Interest is paid monthly, and the principal is returned at the end of the loan term rather than in instalments.
• The AAA–D borrower score is a signal to help you weigh a loan, not investment advice.
• Collateral is held through a Collateral Agent, and the loan-to-value (LTV) ratio is shown so you can see how much backing sits behind a loan.
• A provision fund may absorb temporary delays in interest payments, but it is not insurance and does not guarantee that principal comes back.
• Capital is at risk, including possible total loss, since borrower default and liquidity risk both apply.

Fee Structures: The Silent Portfolio Killer

Investment apps generate revenue through various fee models. Understanding each component prevents erosion of your returns over time.

Trading fees represent the most visible cost. Some platforms charge per transaction—typically £1.50 to £11.95 per trade. Others offer unlimited commission-free trades on shares and ETFs. That sounds attractive until you examine the alternative revenue sources: wider bid-ask spreads, payment for order flow, or higher account maintenance fees.

Platform fees come in multiple forms. Monthly subscription models range from £4.99 to £19.99 depending on service tier. Percentage-based annual fees typically sit between 0.15% and 0.45% of your portfolio value. A 0.45% annual fee on a £50,000 portfolio costs £225 per year. Over 20 years at 6% average returns, that fee difference versus a 0.15% platform could cost you over £8,000 in compound growth.

Foreign exchange fees matter for international investing. When you buy US stocks or global funds, the platform converts your pounds to dollars or other currencies. Standard FX fees range from 0.15% to 1.5% per transaction. A £10,000 investment in US equities with a 1.5% FX fee costs you £150 immediately—before you own a single share.

Fund charges apply when you invest in mutual funds or ETFs. The Ongoing Charge Figure (OCF) represents the annual cost of holding the fund, typically 0.07% for passive index trackers to 1.5% for actively managed funds. Investment apps don't control these fees, but the best platforms clearly display them before you commit.

Inactivity fees penalize dormant accounts. Some providers charge £12 to £40 quarterly if you don't trade or maintain minimum balances. These fees disproportionately hurt long-term buy-and-hold investors, precisely the strategy most likely to build wealth over time.

Minimum Investment Requirements: Lowering or Raising the Bar

Traditional stockbrokers once required £500 to £1,000 minimum deposits. Modern investment apps have largely eliminated this barrier. More than 70% of UK investing apps now accept initial deposits under £50, with several allowing you to start with just £1.

Fractional shares make this possible. Instead of buying whole shares—a single Amazon share costs over $200—you purchase a fraction based on your budget. You can invest £10 and own 0.0005 of a company. This feature transforms portfolio construction for small investors, enabling proper diversification rather than forcing concentration in cheap stocks.

Recurring investment minimums vary significantly. Some platforms let you set up automatic monthly investments from £1. Others require £25, £50, or £100 minimum recurring contributions. If you plan to use pound-cost averaging—investing fixed amounts at regular intervals regardless of market conditions—verify the platform supports your intended contribution level.

Account type minimums sometimes override general platform minimums. A provider might accept £1 for a general investment account but require £500 to open a Self-Invested Personal Pension (SIPP) or £1,000 for a Junior ISA. Read the specific terms for your intended account structure.

Withdrawal minimums and frequencies deserve attention. Some apps require £100 minimum withdrawals or limit you to one free withdrawal monthly, charging £5 to £10 for additional requests. This matters if you need flexible access to your money.

Asset Class Availability: Matching Tools to Strategy

Investment apps differ dramatically in what you can actually buy. The major asset categories include equities, bonds, funds, and alternatives, but availability varies by platform.

UK and US stocks represent the baseline offering. Nearly all investing apps provide access to London Stock Exchange listings and major US exchanges. Coverage expands from there. Some platforms offer 10,000+ equities across 20+ global markets. Others limit you to 500 popular UK and US stocks.

Exchange-Traded Funds (ETFs) have become the preferred vehicle for diversified investing. Low-cost platforms typically offer 1,500 to 3,000 ETFs covering indices, sectors, commodities, and bonds. The best apps include ETF screening tools by expense ratio, asset class, and geographic exposure.

Investment trusts provide another pooled investment option, particularly popular in the UK. These closed-end funds often trade at discounts to net asset value, creating opportunities for value investors. Platforms targeting sophisticated investors usually offer 300+ investment trusts; basic apps may offer none.

Mutual funds appear on platforms aimed at traditional investors and financial advisers. Open-ended funds allow direct investment in actively managed strategies. Approximately 40% of investment apps now exclude mutual funds entirely, focusing instead on ETFs and individual securities.

Bonds and fixed income present challenges for retail platforms. Government gilts and corporate bonds typically trade in £10,000+ minimums in institutional markets. Some apps provide access through bond ETFs and funds; fewer than 20% offer individual bond purchases for retail investors.

Cryptocurrencies blur the line between investing and speculation. Roughly 30% of mainstream investing apps now include Bitcoin, Ethereum, and other digital assets. Regulatory treatment remains uncertain—the FCA does not consider crypto a regulated investment, meaning you lose Financial Services Compensation Scheme protection.

Commodities like gold, silver, and oil appear primarily through ETFs and commodity-tracking funds. Physical commodity investing requires specialized platforms; mainstream apps provide exposure through financial instruments that track underlying prices.

Options, futures, and derivatives demand advanced knowledge and carry substantial risk. Most consumer investing apps deliberately exclude these instruments. The platforms that offer them require you to confirm your experience level and pass knowledge assessments before trading.

Regulatory Protection: Understanding What's Actually Safe

Not all assets on investing apps receive equal regulatory protection. Understanding these distinctions prevents nasty surprises if a platform fails.

The Financial Services Compensation Scheme (FSCS) protects up to £85,000 per person, per firm for deposits and investments if an authorized firm fails. This covers shares, bonds, and fund units held in your name. Crucially, FSCS protection applies only if the firm is FCA-authorized and the failure isn't due to poor investment performance—it protects against firm insolvency, not market losses.

Cash holdings within investing apps fall under different protection rules depending on how they're held. If your uninvested cash sits in an FCA-authorized bank account, you have £85,000 FSCS protection for that cash separately from your investments. If it sits in a non-interest-bearing client money account, protection depends on the platform's client money handling procedures.

Segregated accounts mean your investments are held separately from the platform's own assets. If the platform collapses, administrators can identify and return your holdings. All FCA-authorized investment platforms must segregate client assets, but platforms operating under different regulatory regimes may not.

Nominee account structures mean the platform holds investments in its name on your behalf. You're the beneficial owner, but the legal owner is the nominee company. This is standard practice and doesn't reduce your FSCS protection, but it does mean you don't appear on the company's shareholder register and may not receive shareholder perks.

Platform authorization status determines your recourse. FCA-authorized platforms must meet capital requirements, conduct rules, and client money protections. Overseas platforms regulated in Gibraltar, Malta, or other EU states offer different protections. Completely unregulated platforms—more common in cryptocurrency—provide no safety net whatsoever.

The Financial Ombudsman Service (FOS) provides free dispute resolution for complaints against FCA-authorized firms. If you believe an investing app provided unsuitable advice, executed trades incorrectly, or charged improper fees, FOS can award compensation up to £415,000. This protection doesn't exist for unauthorized platforms.

Peer-to-peer lending platforms, despite the name "investment platform," operate under distinct FCA rules. P2P loans don't qualify as specified investments under FSCS protection. If a P2P platform fails, you might lose both access to your loans and any outstanding repayments. The P2P Finance Association promotes standards, but membership is voluntary and provides no compensation scheme.

Account Types: Tax Wrappers and Pension Structures

The best investing apps support multiple account types, each with distinct tax treatment and rules.

General Investment Accounts (GIAs) offer complete flexibility. No contribution limits, no withdrawal restrictions, no age requirements. The trade-off: you pay capital gains tax on profits above the annual exempt amount (£3,000 for the 2024-25 tax year, reduced from £6,000), and dividend tax on income above £500. For basic-rate taxpayers, that's 8.75% on dividends and 10% on capital gains; higher-rate payers face 33.75% and 20% respectively.

Individual Savings Accounts (ISAs) shelter investments from all UK income and capital gains tax. The 2024-25 subscription limit is £20,000. Stocks and Shares ISAs hold equities, bonds, and funds; Cash ISAs hold deposits; Innovative Finance ISAs hold P2P loans. You can split your £20,000 allowance across types but can only pay into one of each type per tax year.

Lifetime ISAs (LISAs) add a 25% government bonus on contributions up to £4,000 annually for people aged 18-39. You can withdraw funds penalty-free for a first home purchase or after age 60. Early withdrawals for other purposes face a 25% penalty—more than the bonus, meaning you lose money.

Self-Invested Personal Pensions (SIPPs) offer tax relief on contributions at your marginal rate. A basic-rate taxpayer investing £80 receives automatic £20 top-up; higher-rate payers claim additional relief through tax returns. Annual allowance is £60,000 or 100% of earnings, whichever is lower. The catch: you cannot access the money until age 55 (rising to 57 in 2028), and 25% of withdrawals are tax-free with the rest taxed as income.

Junior ISAs allow parents to invest £9,000 annually for children under 18. The child gains control at 18; withdrawals before then are prohibited except in terminal illness cases. Returns are tax-free, and the investments don't count toward the child's £20,000 adult ISA allowance.

Not all investment platforms offer all account types. Approximately 60% provide both ISAs and GIAs. Only 40% offer SIPPs. LISAs appear on roughly 25% of platforms. Verify your desired account type is available before you commit.

User Experience Factors That Impact Long-Term Success

Interface quality affects investment behavior. Platforms emphasizing colorful charts and rapid-fire trading notifications encourage overtrading—academic research shows frequent traders underperform buy-and-hold investors by 6.5 percentage points annually after fees.

Educational resources separate serious investing apps from gambling-adjacent platforms. The best provide research reports, company fundamentals, financial statement access, and investment guides. Platforms offering only price charts and social sentiment feeds encourage speculation over informed decision-making.

Order types matter for execution control. Market orders execute immediately at current prices. Limit orders specify your maximum buy or minimum sell price. Stop-loss orders automatically sell if prices fall to your specified level. Platforms offering only market orders leave you vulnerable to poor pricing, especially in volatile markets or illiquid stocks.

Research and screening tools help identify suitable investments. Quality platforms provide filters by market cap, dividend yield, P/E ratio, sector, and geography. Some offer analyst ratings, earnings estimates, and peer comparisons. Basic apps provide nothing beyond current price and one-year charts.

Customer service quality varies wildly. Premium platforms offer phone support during trading hours. Mid-tier providers offer email and chat support with 24-48 hour response times. Budget platforms rely on FAQ pages and community forums. When you encounter a problem—blocked withdrawals, incorrect trades, account access issues—support quality determines whether it's resolved in minutes or weeks.

Account transfer processes (often called "bed and ISA" or "platform transfers") should be straightforward. Transferring investments in-kind preserves your tax position and avoids selling and rebuying. Some platforms charge £25-£100 for outbound transfers; others waive fees. The best apps complete transfers within 30 days; the slowest take three months.

Making Your Final Decision

Your ideal investment app depends on your specific circumstances, not generic "best of" rankings. A platform perfect for a £100,000 pension portfolio charging 0.25% annually costs you £250 yearly—potentially worthwhile for comprehensive research, superior execution, and SIPP administration. That same platform makes no sense for someone investing £50 monthly in fractional shares who'd pay more in fees than they invest.

Define your investment approach first. Index investors buying and holding global ETFs need low platform fees and broad fund selection but can ignore advanced charting tools. Active traders need real-time data, advanced order types, and low trading commissions but might accept higher platform fees. Income investors need clear dividend reporting and efficient reinvestment options.

Calculate total annual costs based on realistic usage. A platform charging £9.99 monthly but zero trading fees costs £120 annually regardless of portfolio size. A percentage-based fee of 0.35% costs £35 on £10,000, £175 on £50,000, and £350 on £100,000. Run the numbers for your expected portfolio value in years one, five, and ten.

Verify regulatory status through the FCA register before depositing money. Authorized firms display a FCA reference number; you can verify registration at register.fca.org.uk. If a platform isn't listed, your money has no regulatory protection.

The investing app market continues evolving rapidly. Features that command premium fees today become standard tomorrow. Minimum investments keep falling. Asset class availability expands. Fee competition intensifies. But the fundamentals remain constant: understand what you're buying, what it costs, how it's protected, and whether the platform's capabilities match your investment strategy. Get those factors right, and the best investing apps become powerful tools for building long-term wealth.
