Complete Guide: App for Investing in the Stock Market in 2025

The investment landscape in Brazil is undergoing significant transformation. In 2024, according to B3 data, more than 5 million people started investing in the market, consolidating a trend expected to continue in 2025 with an estimated 20% growth. Millennials and Generation Z are leading this movement, seeking platforms with easy navigation, transparent fees, and access to international assets.

The demand for diversification is remarkable. Investors are not only looking for local stocks but also cryptocurrencies, global ETFs, and dollar accounts. In this context, choosing the right app to invest in the stock market has ceased to be optional and has become essential to maximize gains.

What to Observe When Choosing Your Investment App

The number of available apps has grown significantly, making the selection complex. Besides traditional criteria — security, fees, and usability — new features have gained relevance:

• Financial planning tools: Integration with long-term goals
• Educational microlearning: Short videos, interactive tests, and segmented content
• ESG portfolios: Investments based on environmental, social, and governance criteria
• Adaptive technology: AI for trend recognition and portfolio optimization

These differentiators separate ordinary platforms from solutions that truly add value to your stock market investment app.
