Quick Answer
Investment and trading apps offer commission-free access to stocks, ETFs, options, and crypto through mobile-first platforms designed for self-directed investors. Robinhood pioneered zero-commission trading with the simplest interface for beginners. Webull targets active traders with advanced charting, 50+ technical indicators, Level 2 data, and paper trading. eToro enables social investing through CopyTrader, letting you automatically follow experienced investors. Public differentiates with no PFOF, unique options rebates (the platform pays you, not vice versa), and direct Treasury bill access. All four are US-based, commission-free, and best suited for self-directed investors who make their own trading decisions.
