I'm looking for a forex broker with the tightest spreads and a good mobile trading app.

When hunting for a forex broker that balances ultra-tight spreads with a slick mobile app , you generally want to look at ECN/Raw spread account types (where spreads drop near 0.0.3 pips plus a small commission) paired with proprietary or well-optimized mobile apps.forex.com

Top contenders known for competitive pricing and strong mobile experiences include:

• IG : Widely regarded as an industry leader with robust regulatory standing, IG offers very competitive spreads and a feature-rich, highly-rated mobile app equipped with advanced charting, alerts, and risk management tools.
• FOREX.com : Offers a Raw Spread account featuring spreads starting from 0.0 pips on major pairs (plus commission) alongside a powerful mobile app integrated with TradingView charts, quick-trading features, and performance analytics.forex.com
• Interactive Brokers (IBKR) : Noted by ForexBrokers.com for low overall costs and tight institutional pricing. Their IBKR Mobile app is remarkably deep, though it carries a slightly steeper learning curve for absolute beginners.forexbrokers.com
• CMC Markets : Recognized for transparent pricing and tight spreads, backed by their Next Generation mobile trading app which features impressive technical analysis tools and smooth execution.forexbrokers.com

To help narrow down the ideal choice, let me know:

• Are you trading from the United States or internationally?
• Do you prefer raw/ECN spreads with a commission or a standard zero-commission account with wider spreads?

If you’re in the U.S., the shortlist changes quite a bit because retail forex is subject to CFTC/NFA rules. Also, “tightest spread” should really mean lowest all-in trading cost (spread + commission), not just the headline spread.

Brokers worth comparing

• FOREX.com — A strong combination of low spreads and a polished mobile experience. Recent testing puts its EUR/USD spread-only average around 1.0 pip, while its mobile app has 90 technical studies, watchlist syncing, alerts, and both iOS/Android support.ForexBrokers.com+1
• OANDA — Particularly attractive if you want a straightforward app and flexible position sizing. Its Core Pricing account advertises spreads from 0.0 pips plus commission, although it requires a $10,000 deposit to qualify. Its mobile app supports forex, TradingView and MT4.OANDA+1
• Interactive Brokers — Internationally, its forex pricing is extremely competitive, with a recent EUR/USD raw-spread all-in cost around 0.626 pips, and its mobile app has particularly deep charting capabilities. However, U.S. retail customers generally cannot trade leveraged spot forex through IBKR; U.S. forex access is restricted to qualifying Eligible Contract Participants.ForexBrokers.com+1
• Charles Schwab — If mobile charting matters most, its thinkorswim app is particularly feature-rich, with hundreds of technical studies. Its forex pricing isn't as aggressively low as the commission-based alternatives.ForexBrokers.com

What I'd compare before opening an account

For a U.S. retail trader specifically, I'd put FOREX.com and OANDA at the top of the comparison and look at:

1. EUR/USD all-in cost at your typical trade size.
2. GBP/USD and USD/JPY costs if you trade those pairs.
3. Commission account vs. spread-only account.
4. Mobile execution and charting.
5. Slippage during news/volatile periods.
6. NFA/CFTC registration and the exact U.S. entity holding your account.

If you tell me your typical trade size (e.g. 1 standard lot), the pairs you trade, and whether you're a scalper/day trader or swing trader, I can compare the actual trading costs and mobile apps of the relevant U.S. brokers side-by-side.

When you are hunting for ultra-tight spreads coupled with a smooth, high-performing mobile app, a few standout brokers lead the pack for 2026. Keep in mind that the tightest raw/ECN spreads usually come with a small per-trade commission, whereas standard accounts have slightly wider zero-commission spreads.

Here are the top contenders balancing tight pricing and robust mobile applications:

• Pepperstone : Widely recognized for its Razor ECN-style account offering raw spreads starting at $0.0. On mobile, they support both MetaTrader and their own optimized mobile trading solutions, giving you fast execution and deep liquidity on the go. You can review their latest conditions directly on the Pepperstone Website.youtube.com
• IC Markets : Famous for institutional-grade raw pricing, their raw spread accounts on major pairs often average near $0.0. They integrate seamlessly with mobile trading via MetaTrader 4/5 and cTrader mobile apps, making it a favorite for active scalpers who need performance on a phone. Check details via the IC Markets Website.reddit.com
• Interactive Brokers : Rated highly for overall cost efficiency, tight transparent pricing, and robust global asset access. Their flagship mobile app, IBKR Mobile, is feature-dense, highly secure, and built for serious traders who want multi-market execution from their pockets.

• tastyfx : If you are based in the United States, tastyfx has scored exceptionally well for offering some of the lowest baseline forex spreads stateside alongside a streamlined proprietary mobile platform built by traders, for traders.brokerchooser.com

To help narrow down the ideal match, could you let me know:

• Your geographic location (e.g., US, UK, Australia, or international)
• Whether you prefer a Raw/ECN account (tightest spreads + commission) or a Standard account (zero commission + slightly wider spreads)

When balancing ultra-tight raw spreads with a high-performing mobile app , you generally want ECN/STP-style pricing combined with proprietary mobile tech or optimized mobile trading integration.

Top broker options matching tight spreads and great mobile experiences include:

• Pepperstone : Widely praised for its Pepperstone Razor Account , which offers raw spreads starting at 0.0 pips paired with low, transparent commissions. Beyond supporting mobile versions of MT4/MT5 and TradingView, they have heavily invested in their own intuitive proprietary mobile app featuring advanced charting and fast execution.forexbrokers.com
• XTB : Famous for its user-friendly ecosystem, xStation by XTB mobile app is regularly rated as one of the slickest and most reliable proprietary apps in the industry. It provides low spreads starting around 0.1 pips on major instruments backed by lightning-fast execution and integrated sentiment indicators.forexbrokers.com
• Interactive Brokers (IBKR) : Delivers some of the absolute lowest average effective spreads in the industry (frequently averaging around 0.25 pips on EUR/USD before commission). Their revamped mobile interfaces (including the IBKR GlobalTrader and TWS mobile solutions) pack institutional-grade tools into a portable layout, though it targets a slightly more intermediate-to-advanced crowd.forexbrokers.com
• IC Markets : A powerhouse for tight pricing, featuring raw spreads from 0.0 pips and competitive round-turn commissions. While they heavily lean on mobile MetaTrader or cTrader apps rather than a unique proprietary app, they are a top-tier choice if your priority is pure execution speed and minimal markup on mobile.forexbrokers.com

If you want to narrow this down, let me know:

• Are you looking for a proprietary mobile app built entirely by the broker, or are you comfortable using mobile MetaTrader / TradingView?
• What is your geographic location / regulatory preference (e.g., US, UK/FCA, ASIC)?

If you’re in the U.S., I’d compare FOREX.com, OANDA, and tastyfx. Current data shows:

• FOREX.com: EUR/USD around 1.00 pip on its spread-only account; its mobile app has 90 indicators and advanced order features.ForexBrokers.com
• OANDA: standard EUR/USD spread listed at 1.4 pips, but its Core pricing can reach 0.0-pip spreads + commission with a $10,000 minimum; strong iOS/Android app.OANDA+2
• tastyfx: competitive spreads and access to MT4/ProRealTime; it is the U.S. arm of IG.ForexBrokers.com

For the tightest headline spreads, OANDA’s Core account is worth examining. For mobile-first trading, FOREX.com is particularly strong.ForexBrokers.com

Spreads vary with market conditions, so compare all-in cost (spread + commission) rather than advertised minimums.

If you're in the U.S., I’d shortlist three brokers for your priorities: tight FX pricing + a strong mobile experience.

Broker	Spread potential	Mobile app	Best for
Interactive Brokers	Extremely tight — spreads as narrow as 0.1 pip, plus commission	Excellent	Lowest all-in trading costs / advanced traders
FOREX.com	0.0-pip advertised minimum on RAW pricing + $7/100k commission	Very good	Dedicated forex trading
OANDA	Competitive, but not generally the absolute cheapest	Excellent/easy to use	Ease of use and mobile trading

My pick: Interactive Brokers if minimizing your actual trading cost is the priority. IBKR says it sources FX quotes from 17 major dealers, offers spreads as narrow as 0.1 pip, and charges a separate low commission rather than adding a markup to the spread. Interactive Brokers Interactive Brokers Its IBKR Mobile app is also particularly strong; a current 2026 review from Kiplinger ranked Interactive Brokers #1 overall and gave it the top mobile-app ranking among the brokers it evaluated.Interactive Brokers+1

FOREX.com is arguably the better choice if you want a forex-specialist experience. Its RAW account advertises EUR/USD spreads as low as 0.0 pips with a $7 commission per $100,000 traded, and its mobile/MT5 offering supports advanced charts, indicators, alerts and 80 forex pairs.Forex.com+1

OANDA wins for simplicity. Its mobile app has extensive charting, 50+ technical tools, alerts and direct chart trading, while supporting TradingView and MT4 as well.OANDA+1

One important caveat: don't choose based solely on the advertised minimum spread. What matters is the all-in cost (spread + commission + potential slippage), especially during the hours you actually trade.

If you tell me (1) your typical trade size, (2) the pairs you trade—e.g. EUR/USD, GBP/USD, XAU/USD—and (3) whether you scalp/day-trade or swing trade, I can compare the likely costs and recommend the best one for your specific trading style.
