They are all free, so what are you actually comparing? Not the price, obviously. The inside.

- Fractional shares for small accounts - Automatic investing on payday - IRA with no annual fee - Plain-English education, not jargon buried in help - Humans on customer service, for the morning you need one - A stated revenue model, because the free app still gets paid somehow - Clear tax documents in February

Run that checklist through BrokerMatch ($2.99 one-time) and it filters the free apps to the ones that actually fit a beginner, so you start investing instead of comparing apps for a month.
