Investing has never been more accessible. With apps that let you start with as little as $1, there's no excuse not to begin building wealth today. But with so many options, choosing the right app can feel overwhelming.

This guide breaks down the best investment apps for beginners, comparing features, fees, and which type of investor each app suits best.
