Best Mobile Investment App 2026 — Europe iOS & Android

TL;DR

Data shows mobile-first European investors converge on three apps in 2026. Trade Republic wins overall for serious investors, combining a beautiful native iOS/Android app, €1 trades, BaFin regulation, and 2,400+ savings-plan ETFs. Revolut wins for first-timers thanks to multi-currency convenience, simple US stock access, and 30+ currencies in the same app already trusted by 30 million European users. eToro takes third for social and copy-trading enthusiasts with a polished mobile-native experience and zero commission. Lightyear and Bunq Investing round out the runners-up. Winning use case: setting up automated monthly ETF savings plans without ever opening a desktop. Key tip: enable biometric login and set transaction-level passcodes — mobile investing is convenient until your phone is lost or stolen and your portfolio sits behind a four-digit PIN.

Why Mobile-First Investing Reshaped European Brokerage

Five years ago, "mobile broker" meant a stripped-down companion app to a desktop platform. By 2026, the relationship has flipped. Many investors consider the mobile app the primary platform, with desktop access either nonexistent or a secondary convenience. Trade Republic launched mobile-first by design. Revolut's investing module never had a desktop equivalent until late 2024. Lightyear's web platform shipped years after the app.

The shift matters because mobile design constraints force discipline. There is no room for ten chart indicators, eight order types, and a real-time options chain. Mobile-native brokers strip the experience down to what actually drives long-term returns: regular contributions, simple instruments, and clear cost reporting. This suits the vast majority of retail investors better than desktop maximalism.

There are trade-offs. Tax reporting is often weaker on mobile-native platforms. Multi-instrument analysis is cramped on a 6-inch screen. Order entry for complex orders (limit, stop-limit, OCO) is sometimes hidden behind menus. But for the buy-and-hold ETF investor doing €200/month into a global tracker, the mobile-only experience is faster, cheaper, and more pleasant than logging into a desktop platform monthly.

This is the practical reality we tested across the top mobile investment apps available to European investors.

Top 5 Mobile Investment Apps for Europe

1. Trade Republic — Best Overall Mobile Investing

Trade Republic is the German neobroker that defined the modern mobile-first European broker. Its app is one of the best-designed in finance — fast, minimalist, and genuinely pleasant to use. Onboarding takes under 10 minutes via video-ID. Buying an ETF is a 4-tap process.

The fundamentals are excellent: €1 per trade, 2,400+ ETFs eligible for free savings plans starting at €1, fractional shares supported within plans, full German banking license with BaFin regulation, deposit insurance up to €100,000, and up to 4.0% interest on uninvested cash (variable). The app supports 17 EU/EEA countries and is available in English, German, French, Italian, Spanish, and Dutch.

Limitations: limit orders and more complex order types exist but are buried. Tax reporting is acceptable for German residents (auto Bescheinigung), basic for others. No web-based platform until 2025, when a minimal portfolio view shipped — still mobile-first.

2. Revolut — Best for First-Time Investors

Revolut is not the cheapest investment app, but it is the most accessible. The investing module sits inside the Revolut app already used by 30+ million Europeans for currency exchange and travel banking. There is no separate signup, no second password to remember. Buying your first share is a tap from the home screen.

Standard accounts get 1 free trade per month, then $1 per trade. Premium and Metal tiers raise free trade allowances. FX is 0.25% within monthly limits, then 1.0%. Around 2,000+ US stocks are available fractionally; ETF selection is limited (~1000 by 2026). Crypto, commodities, and US bonds round out the selection.

The killer feature is multi-currency. You can hold balances in 30+ currencies, fund investments from any of them, and convert at near-interbank rates within the free monthly allowance. For investors who travel or earn across currencies, this eliminates a layer of friction other brokers impose.

3. eToro — Best for Social and Copy Trading

eToro has built mobile-native social investing into a polished, profitable platform. Its app dominates app-store visibility in many EU countries. Zero commission on stocks, fractional shares, and the unique CopyTrader feature let you mirror experienced investors' portfolios automatically with a configurable allocation.

Where eToro shines mobile-side is the social feed — discussion of stocks, earnings, and macro events flows through the app itself. For investors who learn by watching others, this is genuinely valuable. For purists who consider trading talk noise, it's distracting.

Costs include withdrawal fees ($5), inactivity fees ($10/month after 12 months idle), and currency conversion at 0.5%. Spreads on individual stocks can be wider than direct execution at IBKR. Regulated by CySEC for EU clients, with deposit protection up to €20,000.

4. Lightyear — Best Clean-Sheet Mobile UX

Lightyear is the newest entrant on this list, founded 2020 by ex-Wise engineers. The app prioritizes clarity: no CFDs, no copy trading, no crypto, no influencer ads in the feed. Just stocks and ETFs, currency interest, and clean reporting.

Pricing is transparent: $0.20 per US share, €1 per EU ETF trade, 0.35% FX. Around 5,000 instruments are available, regulated by the Estonian FSA, and deposit protected up to €20,000 under the Estonian Investor Protection Sectoral Fund. The app's currency interest module pays competitive rates on uninvested EUR, USD, and GBP balances.

For investors who find Trade Republic too austere or Revolut too cluttered, Lightyear hits a middle ground. Its weakness is instrument breadth (5,000 vs Trading 212's 13,000) and lack of true savings plans (workaround: scheduled top-ups + auto-buy lists).

5. Bunq Investing — Best Bank + Investing Hybrid

Bunq is a Dutch neobank that added an investing module in 2023, expanding through 2025. The novelty is genuine integration: your investments sit alongside your current account, savings sub-accounts, and joint accounts in the same app, with a unified balance view.

Investing options are limited to a curated list of about 250 stocks and 100 ETFs at the time of writing — mostly large-cap US names and major UCITS ETFs. Fees are €2.99 per trade (Easy Investments tier; lower on premium plans). Fractional shares supported. Regulated by DNB (Dutch Central Bank) with deposit insurance up to €100,000 for cash; investments segregated separately.

For Dutch, German, and Belgian users who want one app for everything financial, Bunq is genuinely compelling. For investors building large portfolios, the per-trade fee and limited instrument list are real constraints.

Comparison Table

Real-World Cost Example

We modeled two scenarios for European mobile investors in 2026.

Scenario A: €500 lump sum into VWCE (Vanguard FTSE All-World UCITS Acc, EUR-denominated)

VWCE is EUR-denominated, so no FX cost.

• Trade Republic: €1 commission. Total cost: €1.
• Revolut Standard: ETFs may be unavailable depending on country; if available, $1 per trade ≈ €0.93. Total: ~€0.93.
• eToro: €0 commission, no FX (already EUR), small spread on execution (~0.05% = €0.25). Total: €0.25.
• Lightyear: €1 commission, no FX. Total: €1.
• Bunq: €2.99 commission. Total: €2.99.

For a single EUR ETF trade, eToro and Revolut nominally win — but spread costs at eToro can match the headline savings.

Scenario B: €100/month savings plan into VWCE for 12 months

This is where the real differences emerge.

• Trade Republic: €0 per savings plan execution × 12 = €0 annually. True automation.
• Revolut: No native savings plan. Manual repeat orders × 12 = $1 × 12 = ~€11/year.
• eToro: No native savings plan, no scheduled investing for ETFs. Manual repeat = ~€3/year in spreads.
• Lightyear: Scheduled top-ups + auto-buy lists, but per-trade €1 still applies = €12/year.
• Bunq: No automated savings plans on standard tier. Manual = €36/year (€2.99 × 12).

The €0 savings-plan structure at Trade Republic translates to several hundred euros saved over a 10-year DCA strategy. For monthly investors, this single feature changes the calculus.

Best for European Investors Specifically

Country availability is uneven across mobile-native brokers:

• Germany / Austria: Trade Republic dominates with native German UX and BaFin protection. Scalable Capital is a strong alternative not on this list.
• France: Trade Republic and Revolut both available; Boursorama and Yomoni are local mobile alternatives.
• Netherlands / Belgium: Bunq Investing has natural advantage; DEGIRO and Bux Zero compete locally.
• Poland: Revolut, eToro, Trade Republic, Lightyear available. XTB is the strongest local mobile broker not covered here.
• Italy / Spain: Trade Republic available since 2023, Revolut everywhere, Fineco's mobile app is exceptional for Italian residents.
• Nordics: eToro and Revolut universal; Nordnet's app dominates locally.

Tax wrappers matter: most mobile-native brokers do not yet support country-specific tax-advantaged accounts (PEA, ISA, IKE/IKZE, ISK). For tax-sheltered investing, a domestic broker is usually required, even if its app is uglier.

Common Pitfalls

Phone loss or theft turns into account loss. Mobile-only brokers depend entirely on your device security. Set transaction-level passcodes separate from device unlock, enable biometric authentication, and have a recovery plan. Trade Republic and Revolut both support recovery via verified email + ID re-verification, but the process takes days.

Push-notification trading regret. Mobile apps surface every market move. The temptation to react to a 3% intraday move is real, and bad. Investors who keep mobile apps installed but disable push notifications for individual stocks tend to outperform those who don't.

Cramped order entry leads to fat-finger trades. On a phone screen, the difference between buying €100 and €1,000 is one decimal place. Always re-read the order summary before confirming. Use the biometric confirmation step as a forced pause.

FX bleeds invisibly on multi-currency apps. Revolut shows USD prices for US stocks, but the conversion happens in the background at 0.25% (or 1% above limits). The fee is real; it just isn't displayed line-by-line.

Savings-plan eligibility is narrower than the broker's full instrument list. Trade Republic offers 12,000+ instruments to trade ad-hoc but only 2,400+ ETFs in free savings plans. If the ETF you want isn't on the savings-plan list, you'll pay €1 per execution.

Tax reporting on mobile is rarely as good as desktop. Year-end documents are usually downloadable PDFs, not interactive reports. Plan to export and process in a spreadsheet or dedicated tracker.

How We Ranked

Five factors weighted as follows:

1. Mobile UX quality (30%) — Hands-on testing of onboarding, daily-use flows, app store ratings, crash rates from third-party data.
2. Total cost of ownership (25%) — Commission, FX, custody, dividend handling for a representative €25,000 portfolio with €200/month contributions over 5 years.
3. Instrument breadth (15%) — Stocks, ETFs, bonds, crypto where relevant.
4. Regulatory and deposit protection (15%) — Tier-1 EU regulator, deposit insurance level, segregation of client funds.
5. Country availability (15%) — Number of EU/EEA countries supported.

We installed each app, opened accounts, executed real trades, and used each as the primary investing platform for at least two weeks. Fees and features change frequently — verify on the broker's site before opening an account.

Alternatives if These Don't Work

• N26 for German residents who want a banking + investing combination (added investing module in 2024). Limited but improving.
• Trading 212 for users who prefer a polished mobile experience with zero-commission stocks, fractional shares, and Pies — covered in detail in our fractional-shares roundup.
• XTB Mobile for Polish, Czech, and Hungarian investors who want strong local-language UX and KNF regulation.
• Bux Zero for Dutch and German investors wanting an ultra-simple alternative to Trade Republic.
• Saxo Mobile for serious investors who need professional-grade analysis on the go alongside investing — costlier, more capable.

FAQ

Are mobile-only brokers as safe as desktop brokers? Regulatory and deposit-protection rules apply identically. The mobile-vs-desktop distinction is purely UX. A BaFin-regulated broker like Trade Republic is just as safe on mobile as a BaFin-regulated traditional broker on desktop.

Can I do tax reporting from my phone? Yes, but the experience varies. Most mobile brokers issue annual tax statements as PDFs. Country-specific tax filing usually requires uploading these PDFs to your tax authority's portal, which is rarely a mobile-native experience.

Is fractional investing safe on mobile apps? Fractional shares are held in nominee structure regardless of platform. The structure is well-established and regulated; mobile vs desktop is irrelevant to legal ownership.

What if I want to switch brokers later? Most mobile brokers support outbound transfers (ACAT-equivalent in EU is a manual broker-to-broker transfer). Costs range from €0 (Trade Republic) to €25 per position (some platforms). Fractional shares typically must be sold first.

Can I run multiple mobile broker apps simultaneously? Yes, and many investors do — for example, Trade Republic for ETF savings plans, IBKR for global stocks, Revolut for casual fractional buys. Track total exposure across apps with a portfolio aggregator.

Track Multiple Mobile Brokers in One Place

The downside of running two or three mobile broker apps — to capture each one's strengths — is that no single app shows your true total portfolio. Freenance tracks positions across multiple investment apps and consolidates cost basis, allocation, and performance into one dashboard, so you can keep using your favorite mobile brokers while still seeing the full picture in a single place.
