Complete Guide: How to Choose the Best App to Invest in the Stock Market in 2025

The investment landscape in Brazil is undergoing transformation. In 2024, more than 5 million new investors entered the stock market, according to B3 data, and forecasts indicate a 20% growth for this year. Millennials and Generation Z are leading this expansion, seeking platforms with user-friendly interfaces, transparent fees, and access to international assets.

In this context, choosing the right app to invest in the stock exchange has become a crucial decision. The proliferation of options in the market requires careful analysis of selection criteria and understanding of the different value propositions offered by each brokerage.

Essential Criteria for Evaluating Investment Apps

When looking for an app to invest in the stock market, various factors go beyond traditional security, fees, and usability:

Integration with Financial Planning
Platforms offering long-term goal tools and profitability projections stand out among structured investors.

Personalized Financial Education
Microlearning content—short videos, interactive quizzes—facilitates continuous learning without interrupting operations.

Sustainability and ESG
Investment options focused on environmental, social, and corporate governance meet the growing demand for responsible investing.

Smart Technology
Use of AI for trend analysis and automatic portfolio optimization represents the competitive edge in 2025.

Access to Global Markets
Accounts in dollars, easy access to international exchanges (NASDAQ, NYSE), and crypto assets reflect the search for diversification.
