2025: What is the Best App to Invest in the Stock Market in Brazil? A Complete Guide

The Brazilian investment market is booming. In 2024, more than 5 million new investors opened their first accounts, and projections indicate a 20% growth in 2025, with millennials and Generation Z leading the way, seeking agile platforms with fair fees. In this scenario, choosing the right app to invest in the stock market has ceased to be a secondary issue and has become a key factor for financial success.

The expansion is happening because now Brazilian investors are no longer satisfied with only local stocks. The demand for cryptocurrencies and international investments has exploded, forcing brokerages to offer dollar accounts, real-time analysis, and innovative financial education. Platforms that do not keep up with this transformation fall behind.

Why Does Choosing the Right App to Invest in the Stock Market Matter So Much?

Many beginners underestimate this initial step. After all, it’s “just” an app, right? Wrong. The investment app is the gateway to your wealth. A good app for investing in the stock market combines robust security, competitive fees, and tools that truly make life easier for investors.

The criteria have evolved. It’s no longer just about security and zero brokerage fees. Now investors demand:

• Integration with long-term financial planning
• Educational content in microlearning format (short videos, interactive quizzes)
• ESG options and sustainable investments
• AI and predictive technology to optimize portfolios

Industry data shows that investors who use apps with good usability and integrated education are 30% more likely to keep their investments for over 2 years. That’s a real advantage.

Market Highlights in 2025

Banco Inter - Inter Invest

Inter Invest has established itself as a solid option for those starting safely. With 4.8 stars and zero brokerage fees (except B3), the app is especially attractive to microinvestors and beginner profiles.

The key feature is ease: if you are already a digital bank customer, everything becomes even simpler. The quality educational material compensates for being linked to an Inter account. Many users praise the simplicity of the interface.

Rating: Best for beginners who already use the bank

XP Investimentos

XP has grown exponentially in recent years because it reinvented itself. It started serving high-net-worth clients and now offers an accessible app even for regular individuals. The value simulator is a lifesaver: you can project your gains before making the contribution.

With 4.6 stars, it operates across multiple domestic and international assets. Stocks and BDRs have a fee of R$ 2.90 (day trade) or R$ 4.90 (swing trade), which is competitive. The platform offers expert analysis (for larger accounts), adding value.

Rating: Ideal for intermediates with diversified portfolios

Nu Invest (Nubank)

Nubank entered the segment through the acquisition of Easynvest, creating Nu Invest. With over thousand products available (stocks, real estate funds, ETFs), the app opened the market to young people who previously thought investing was only for traditional banks.

4.6 stars rating, zero fees on certain products, and Pix integration make life easier. The “Safe Mode” is designed for more conservative profiles, offering recommendations aligned with your risk profile.

Rating: Perfect for beginners and conservatives

Avenue

Avenue is the gateway for those wanting to invest abroad safely. Robust anti-fraud system, dollar accounts, and access to US SPACs and direct American assets make it a unique option.

Brokerage costs vary in dollars, and it is more suitable for investors with prior knowledge. But for those seeking global diversification, it’s practically essential.

Rating: Essential for international investments

Toro

Operating since 2017 and now under Banco Santander’s custody, Toro Investimentos has established itself as a reference in technology and security. The app offers a well-structured “Investor Journey,” great for learning while investing.

4.4 stars, various brokerage models (you choose between zero fee or percentage on profit). Robust educational material that keeps no one confused.

Rating: Best for those wanting a personalized experience

Rico

Rico has become synonymous with young investing in Brazil. Casual language, intuitive interface, and fees that don’t eat into your profits have won over generations. Besides stocks and bonds, it offers investment funds with integrated education.

4.4 stars, zero brokerage fee (except B3). Part of the XP group, which builds trust but raises questions about market concentration.

Rating: Best for beginners who value community

Mitrade

Mitrade arrives as a disruptor in the Brazilian market. Several international awards for security, cutting-edge technology, and a different approach: a demo account to practice before investing real money.

The app offers stocks, cryptocurrencies, FOREX, gold, crude oil, and other global assets, all with real-time charts and free market analysis. Zero brokerage fees and free account opening remove entry barriers.

4.6 stars, ideal for beginners to intermediates seeking global exposure. The key feature is the demo account—you train, learn the market, and gain confidence before risking real money.

Rating: Revolutionary in education and security

What Really Changes Your Decision?

After analyzing each platform, three factors emerged as decisive in 2025:

Security and Reputation: Every app must have certifications and demonstrate solidity. No shortcuts here.

Integrated Education: Apps that teach while you invest produce more qualified and less impulsive investors. This reduces losses.

Transparent Fees: The market has evolved so much that “zero fees” has become standard in many operations. The differentiator now is the absence of hidden charges.

Conclusion: The Ideal App to Invest in the Stock Market in 2025

There is no “best app to invest in the stock market” in absolute terms. There is the best for you, your profile, and your goals. Beginner? Rico or Mitrade. Conservative? Nu Invest. Intermediate aiming abroad? Avenue or XP.

What matters is to start. With over 5 million new investors entering the market annually and international diversification on the rise, wasting time choosing means leaving returns on the table. Download an app today, explore the demo account if available, and start your journey.

2025 promises to be the year when investing ceases to be a privilege for the few. Choose your app to invest in the stock market and don’t fall behind.
